Definitions

• the invention relates to a stop device for a miter saw according to the preamble of claim 1 and a miter saw with a stop device according to the invention.
• the known stop devices are combined with a swiveling saw which, when swiveled, sweeps over an angle scale on a support of the stop device. For example, to saw a skirting board for the corner of a room, first measure the angle of the corner, then set the saw to half the angle, and then miter the corresponding bar against the stop. Then the saw is swiveled by the measured angle into the opposite half of the support and then the complementary skirting board is sawn. Apart from the fact that this method is cumbersome, there is also the disadvantage that incorrect calculations of the angle halves are only recognized when the skirting boards are joined, that is after sawing.
• a miter saw is known with two stop means pivotable in a plane formed by a support, an bisector of the angle enclosed by the stop means always being fixed to the support and with the cutting plane of the saw blade coincides.
• the disadvantage here is that the position of the cutting area of the saw with respect to the support is dependent on the miter angle set, particularly in the case of very acute or very obtuse miter angles in the edge regions of the support. This requires a correspondingly large immersion of the saw blade in the stop device and thus a high risk of injury and a large design.
• the two stop means firmly connected to the gear connection attached to the underside of the support must be set back radially outward far enough from the area of the bisector to enable sawing of wider strips, in particular at acute and obtuse angles. This also increases the risk of injury and increases the size.
• the invention is therefore based on the object of providing a stop device of the type mentioned at the outset and a miter saw which are simple and safe to use, ensure precise miter cuts, and are small and easy to implement.
• This object is achieved according to the invention by a stop device with the features of claim 1 and a miter saw with the features of claim 15.

• the immersion depth for example of a saw blade in the support, is only determined by the workpiece to be sawn and is in particular independent of the set miter angle. This not only increases operational safety, but also reduces the size and mass of the stop device or the associated miter saw.
• the special embodiment of the invention according to claim 2 has the advantage that the distance from the stop rail to the bisector or to the common axis corresponding to the set miter angle and / or to be sawn by the stop rail which can be displaced in the radial direction with respect to a stop block in relation to the common axis Workpiece can be adjusted. As a result, a more precise • guidance and thus a more precise miter cut are achieved. In addition, the operational safety of the stop device is increased and the risk of injury is minimized. An automatic displacement of the stop rail relative to the stop block in dependence on the set miter angle by mechanical coupling of the pivoting movement with a displacement movement of the stop rail in relation to the stop block is also particularly conceivable.
• the special embodiment of the invention according to claim 3 has the advantage that the stop means can be fixed in the position of the set miter angle.
• the determination can be made in particular by clamping the sling means to the support or by blocking the swivel mechanism, for example directly on the common axis.
• the corner angle to be sawn can be removed by means of a cuddle, the cuddle can then be placed on the support and the stops can be brought into contact with the cuddle and can be determined.
• the special embodiment according to claim 4 has the advantage that such a swivel arm guide of the lifting means can be realized with a low overall height and low mass. In addition, it has only a few moving parts and therefore only a low mass inertia when adjusting. In addition, a hermetic seal is not required and, with relatively simple structural means, there is little mechanical play Stop device accessible. Due to a mirror-image construction with respect to the bisector, the number of individual parts required and thus the manufacturing costs of the device are reduced. The arrangement is low-noise during adjustment, easy to install and service, and maintenance-free.
• the special embodiment of the invention according to claim 5 has the advantage that the number of parts required is further reduced by the direct guidance of the joint along the bisector below the support with the associated advantages mentioned above.
• the pivot levers are preferably cranked or bent around the common axis according to claim 6, whereby the size and mass is further reduced.
• the guidance of the joint can either be carried out according to claim 7 by a slide-like guide on a guide rod or according to claim 8 by guiding a pin or sliding block in a groove made in the underside of the support and aligned with the bisector.
• the special embodiment of the invention according to claim 9 has the advantage that the mechanical coupling by means of two swivel plates ensures particularly precise guidance, which can also transmit high torques.
• the special embodiment of the invention according to claim 10 has the advantage that the combination of a gear connection and a further gear connection ensures a particularly precise guidance of the stops during the pivoting movement.
• the device according to claim 1 1 has the advantage that through the use of a belt connection a permanently reliable and inexpensive guidance of the Sling is guaranteed and in particular the use of a toothed belt further improves the accuracy of the guide.
• the special embodiment of the invention according to claim 12 has the advantage that the use of three appropriately arranged bevel gears can reverse the direction of rotation of the pivoting movement of the two stop means with little mechanical play.
• the bevel gears can also be designed as friction wheels, but preferably, according to the embodiment according to claim 1 3, are conical gears, whereby the transmission of high torques is guaranteed with precise guidance.
• the special embodiment of the invention according to claim 14 has the advantage that such a rope, belt or chain hoist guide is structurally particularly easy to implement.

It is advantageous that an exact cut is possible due to the swiveling saw, preferably circular saw, which is aligned with the bisector according to claim 16. Together with the stop device according to the invention, a precise miter cut is thus ensured for all possible angles.
• the special embodiment according to claim 1 7 has the advantage that such a miter saw can also be used to saw strips whose ends are to be provided with a miter cut in relation to two surfaces. Correspondingly, when operating such a miter saw, two angles have to be removed with the cuddle.
