Drill holder for a hand drill

The invention relates to a drill holder for
a hand drill, with a drill neck
comprehensive clamping ring which has a fastening foot.

There are drill holders known in the one

there is therefore a risk that it will get into the running unit
intervenes from the drill and additional equipment to make any adjustments or changes. A
such intervention is of course extremely dangerous. Another risk is that a

Any piece of clothing or a rag that comes near the drilling machine is wound up by the machine. s Protective hoods for drill holders are also known.

The object of the invention is to provide a drill holder

prevents.

To solve this problem, according to the invention, the clamping ring a protective hood protruding to the front, which is bent into a U-shape and open at the bottom, around a horizontal one Axis mounted pivotably.

The protective hood can be easily swiveled up to gain access to the drill chuck. After the During the intervention, the protective hood is simply folded down and fastened with a grub screw, where it is held while the operation is running Hand drill remains. This practically eliminates any risk from the rotating drill shaft.

According to a further invention, in the case of the drill holder of the type mentioned at the beginning, one can be attached to the clamping ring be attached to the front protruding support rod for an auxiliary device driven by the drill.

The holding rod can serve, for example, the additional device with respect to the housing of the hand drill to hold firmly in place while the shaft of the additional device is driven by the drill shaft.

or an open ring The clamping ring can consist of two ring halves /, whose lower ends are firmly connected to one another and the upper ends of which have flanges that are secured by a screw are pullable against each other. In this way, the drill neck is firmly clamped with a single one Clamping screw. This clamping screw can simultaneously form the pivot axis for the protective hood when this one Has holding element which engages between the flanges of the clamping ring and a hole for inserting the

In the following an embodiment of the invention is explained in more detail with reference to the figures.

_ijS Fig. 1 shows a perspective view of the drilling machine

internal bracket with clamped drill and a pump as an additional device,

Fig. 2 shows a side view of the assembly shown in Fig. 1, and

Fig. 3 shows a section along the line III-III of Fig. 2.

According to FIG. 1, the hand drill is on a wooden board 10 11 attached to the drill holder 12. The drill holder 12 has a clamping ring 13 as well as a fastening foot 14 and a protective hood 15. The clamping ring 13 is with the on both sides protruding foot 14 placed on the wooden board 10 and screwed tight with screws 16. In the clamping ring 13 is the neck of the hand drill 11 is inserted and then clamped by tightening the screw 17, wherein the hand drill is attached to the wooden board 10 with the top facing downwards, so that its handle 18 is facing up.

On the drill holder 13 is a forward protruding Holding rod 19 is attached, which protrudes through an opening in the pump housing 20. The pump housing 20 contains an impeller driven by the drill shaft and has an intake port 21 and an outlet

let socket 22 open.

The details of the construction emerge from the representations of FIGS. 2 and 3. The clamping ring 13 consists of two symmetrical parts 131, 132, which are bent outwards at their lower ends and form the foot 14. Above the foot 14, the clamping ring parts 131 and 132 include a threaded sleeve 21 into which a thread on the End of the support rod 19 is screwed. In this way the holding rod 19 is between the two clamping ring parts 131 and 132 held so that they are free, roughly parallel to the board 10 protrudes forward. Above the threaded sleeve 21, the clamping ring parts 131 and 132 form approximately one Circle for enclosing the drill neck 22. The upper ends of the clamping ring parts 131 and 132 are as flanges 23 which have an opening through which the screw 17 is inserted. When tightening the Screw 17 or the nut sitting on it, the flanges 23 are pulled against each other, so that the drill neck 22 is firmly clamped.

Between the two flanges 23 there are two parallel metal sheets 24, which also have holes through which the screw 17 passes through it. The sheets 24 are components of angle pieces 25 that are attached to the top of the Protective hood 15 are welded. In this way, the screw 17 forms the joint for pivoting up the protective hood 15 in the position designated by 15 'in FIG. 2. The protective hood can be swiveled further back so that it lies above the hand drill 11. In this way there is direct access to the drill chuck 26, in which the input shaft 27 of the pump 20 is clamped. The pump 20 protrudes with a cylindrical

7810213 07/13/78

set 28, in which the input shaft 27 is mounted, on the end face to under the protective hood 15 so that no rotating parts are accessible from the outside.

As can be seen in particular from FIG. 3, the protective hood 15 has is inverted-D-shaped with its front edge 29 having notches 30 and rectangular is bent inwards. In this way it is achieved that the edge of the edge 29 the cylindrical projection 28. Der Entrengrond 29 und das cylindrical shoulder 28 encloses with a small distance.

To the folding of the protective hood to allow to the pump housing 20 past its leading edge is beveled at 31, as illustrated particularly in Fig _t 2 can be seen.

On the flange 23 of the one clamping ring part 132 is a locking screw 32, which is in a (not shown Hole of the corresponding plate 24 engages when the protective hood 15 in the lowered state and the Locking screw 32 is screwed in. In this way it is prevented that the protective hood 15 inadvertently is swung up.
