Abstract

Table saw, comprising a work surface (3) for receiving a workpiece (7), a saw blade (2) for sawing the workpiece (7) while the saw blade is in a working position, the table saw (1) being set up in such a way that the saw blade occupies a safety position can, in which it is arranged completely below the work surface (3).

Description

The invention relates to a table saw.

Because of the rotating saw blade, working on a table saw is always associated with a potential hazard.

It is the object of the invention to increase safety when working with a table saw.

According to the invention, a table saw is proposed according to claim 1, embodiments are disclosed in the subclaims and the description.

• 1 ein Tischkreissäge in perspektivischer Darstellung mit dem Sägeblatt in einer Arbeitsposition;
• 2 schematisch eine Verstelleinrichtung für das Sägeblatt;
• 3 die Tischkreissäge nach 1 in perspektivischer Darstellung mit dem Sägeblatt in einer Sicherheitsposition;

The invention is explained in more detail below with reference to the figures; here shows:

• 1 a table saw in a perspective view with the saw blade in a working position;
• 2 schematically an adjusting device for the saw blade;
• 3 the table saw 1 in a perspective view with the saw blade in a safety position;

The table saw according to the invention 1 includes a saw blade 2 , which on a saw frame 21st is mounted. One workpiece 7th , which on a work surface 3 is guided by the saw blade 2 sawn. The saw blade is during the sawing 2 in a working position, as in 1 is shown.

One sensor 4th is provided, based on which it is detected when the workpiece assumes a predefined position. The position of the sensor can be determined using a sensor holder 41 can be changed and thus adjusted to an individual workpiece. As soon as the workpiece has been completely sawn, the sensor is activated by the workpiece. In a simple embodiment, the sensor can be a switch which is switched from an OFF state to an ON state by the workpiece itself.

The activation in turn sets an adjusting drive 6th in progress. The adjusting drive includes an adjusting motor 61 as well as an adjusting gear 62 . The saw blade is on a saw frame 21st held. The adjustment drive can be the saw frame 21st relocate and lower the saw blade under the work surface in the safety position.
