Handle for a hand-held tool

The invention relates to a handle for a hand-held working device of the type specified in the preamble of claim 1.

When producing work using hand-held tools such as drills and the like, the tool is often put down in order to insert a tool required for the next operation. Often, after using the tool in one operation, the location for the next operation must be determined. This location is usually marked by the operator before the tool is used again.

Often, the work with the implement is prolonged because the operator has to put the implement aside in order to prepare for the next operation in order to fetch the required equipment parts, which is often perceived as annoying.

DE 85 11 533 Ul discloses a hand drill whose additional handle is designed as a hinged container in which replacement drill bits or a magazine for drill bits are provided as additional equipment for the drill. Small screwdrivers or a key for tightening the chuck of the hand drill can also be stored in the magazine. If, when working with the known drill, a different drill bit needs to be clamped for the next step, the operator can take the desired replacement drill bit from the magazine on the spot. This means that there is no need to fetch the replacement drill bit, which often leads to a search for the drill bit supply.

EP 0 280 769 A1 discloses an additional handle for drilling machines, in which the handle is designed as a revolver magazine for drills and screwing tools. CH 675 388 A5 discloses making the additional handle of a hand drill hollow and storing a magazine with replacement drills there. The drill magazine of the known hand tool can be inserted into the additional handle and locked into place to ensure that the replacement tools can be stored in a rattle-free and protected manner. When the hand drill is in use, however, the carrier magazine should be removed from the handle to reduce the weight during operation.

The present invention is based on the object of developing a handle for a hand-held tool

•&Ggr;T;^3fcUÄiUtt€lduög*n\41017.b.doc

to facilitate the work to be carried out.

This object is achieved according to the invention with the features of claim 1.

According to the present invention, means for marking the surface to be worked with the tool and a measuring tape are implemented in the handle of the tool. When working with the tool, between the individual work steps, necessary markings on the object to be worked on and for measuring it, in particular for the purpose of subsequently marking the processing points, can be made directly with the equipment of the tool. Therefore, if it is necessary to apply a marking when using the tool, this can be done immediately with the means according to the invention. A complete marking set is available in the handle according to the invention and the previously necessary fetching of the marking means, which would be very annoying especially when working on ladders, is therefore no longer necessary. The measuring tape is arranged in a pull-out manner in the housing of a known measuring tape cassette, which is removably accommodated in a slide-in housing at the free end of the handle.

If the tape measure cassette is inserted essentially orthogonally to a longitudinal axis of the handle, the operator can easily remove the tape measure with his or her other hand.

while the other hand continues to hold the handle firmly. The insert housing for the tape measure cassette is wider than the diameter of the handle and stabilizes the operator's handle when using the tool and prevents it from slipping lengthwise.

A marking pen is preferably used as the marking means, which can be inserted into the magazine in the handle from the free end of the handle. The marking pen can thus be pulled out of the magazine for use as required and is just as easy to insert again after marking work has been carried out. In a preferred embodiment of the invention, the magazine for the marking means is designed as a plug-in component, which can be inserted into the hollow handle from the free end. In this way, the magazine is carried in the handle of the tool in a space-saving manner. The magazine for the marking set and the insert housing for the tape measure cassette are expediently designed as one piece, with the magazine with the marking means being able to be inserted into the handle up to the level of the molded insert housing, which forms a stop for the insertable part of the plug-in component. In the rest position, the plug-in component is releasably locked into the handle, whereby the insert housing at the free end of the handle contains the tape measure cassette and offers it for removal as required.

Wooden casing marking pens such as pencils and the like are advantageously used, with a sharpening device for the marking pen being advantageously formed at the end of the plug-in component opposite the tape measure insert. The opening of the sharpening device for inserting the end of the marking pen to be sharpened is advantageously located in a plane substantially orthogonal to the longitudinal axis of the plug-in component, with the marking pen to be sharpened being able to be inserted into the sharpening device in the longitudinal direction of the magazine, i.e. parallel to its rest position.

A rotatable ring containing the opening for the marker pen is conveniently arranged on the sharpening device. This opening can be designed according to the cross-sectional shape of the marker pen, for example a flat carpenter's pencil.

For example, a small flashlight can be housed in the magazine; instead of this or in addition to this, a container with a drilling emulsion or similar can also be provided. The container should include a spray device for the appropriate application of the drilling emulsion.

In addition to the marking means according to the invention, the magazine for additional equipment advantageously also contains replacement tools for the tool, so that work with the tool can be carried out even more comfortably. In the preferred application example of the invention in a handle for drilling machines, the magazine contains

&Euro;

The marking set according to the invention, consisting of, for example, a marking pen and the sharpening device, as well as the measuring tape carried according to the invention are expediently provided in an additional handle which is provided for guiding the tool on the work device.

The measuring tape cassette is easy to remove and is secured in position against operational vibrations when the tool is in operation if it is held in the locking position and in the slot by means of a spring element. The spring element is preferably designed as an essentially U-shaped clamp. When the clamp is pushed onto an edge of a wall of the slot housing that limits the opening of the slot or onto an intermediate wall inside the housing, the clamp legs are expanded by the wall and the clamp is held in place by the elastic restoring force. The clamp is expediently connected to the measuring tape cassette. The measuring tape cassette can thus be held in place with the clamp outside of the locking position in the slot housing, for example on the operator's clothing. The measuring tape cassette is held in the slot housing by a locking lug protruding from the slot housing, which then snaps into an opening in the outer clamp leg.

Embodiments of the invention are explained in more detail below with reference to the drawing.

Fig. 1 shows a hand-held drilling machine 1, in the main body 2 of which the drive means, in particular an electric motor, for the drilling tool are arranged. The drill is clamped in a drill chuck 7, which can be driven with the drill in rotation about the spindle axis 6 by the motor via the drive spindle 8. The drilling machine 1 is held by the operator with a handle 4 at the rear end of the main body 2, this handle being provided with the operating switch 5 for driving the drilling machine 1 and means for supplying power 11 also being provided on this handle 4. The tool is guided by an additional handle 3, which is arranged with a fastening sleeve 10 near the drill chuck 7. The additional handle 3 is arranged with its longitudinal axis 14 essentially orthogonal to the spindle axis 6 and lies essentially in the same plane as the rear handle 4 in order to make the drilling machine 1 easier to handle, whereby the rear handle 4 with the operating switch 5 and the additional handle 3 with its cylindrical surface 12 can be comfortably gripped by the operator. The additional handle 3 is detachably held with the fastening sleeve 10 on a bearing bed 9 for the drive spindle 8 belonging to the housing of the main body 2.

The additional handle 3 is hollow and accommodates in its interior approximately over the length of the gripping surface 12 a plug-in component which can be designed as a magazine 28 for additional equipment parts of the drilling machine 1. The plug-in component 28 is explained in more detail in Fig. 2 and 3 described later. The plug-in magazine is inserted into the handle 3 with its end opposite the free end 13 and can be pulled out in the opposite direction, whereby in the rest position shown in Fig. 1 a plug-in housing 15 for a tape measure cassette protrudes from the lower end 13 of the handle 3. The plug-in housing has larger dimensions than the cross-section of the handle 3 and forms a stop for the plug-in component.

Fig. 2 shows a perspective view of a plug-in component 16 for the additional handle 3 of the drill 1 according to Fig. 1. The elongated part that can be inserted into the handle forms the magazine 28, which is provided with a guide that stabilizes the insertion movement of the magazine 28 into the handle. The magazine 28 can be inserted into the handle until it rests against the insert housing 15 formed at the lower end, with a latch 36 latching into the handle belonging to the drill housing in the stop position. The plug-in component 16 can be removed from the handle by pressing the latch inwards. The magazine 28 contains replacement tools for the work device; in the present embodiment, screwdriver bits 35 are provided.

At the lower end of the magazine 28, a slide-in housing 15 is formed as one piece on the plug-in component 16, in which a tape measure cassette 17 is accommodated. Such a tape measure cassette 17, as shown for example in Fig. 7, essentially consists of a cassette housing 18 in which a wound-up tape measure 22 is accommodated and can be pulled out of the housing 18 through an opening as required. The tape measure cassette arranged in the slide-in housing 15 of the plug-in component 16 for the additional handle is held essentially orthogonal to the longitudinal axis of the handle, i.e. corresponding to the longitudinal axis of the plug-in magazine 28 of the plug-in component 16. The tape measure cassette 17 is held in the latched position by a spring clip 19. For this purpose, as shown in Fig. 2, the insert housing 15 is provided with a recess 35, under which a housing intermediate wall 27 extends, which is pushed between the legs of the U-shaped spring clip 19. As can be seen from the schematic view in Fig. 9, the U-shaped spring clip 19 is connected to the housing 18 of the measuring tape cassette 17, with an inner clamp leg 20b being connected to the housing 18 via a screw 21. When the measuring tape cassette is inserted into the insert housing 15, the housing intermediate wall 27 displaces the outer clamp leg 20a in the direction of the arrow.

The tape measure cassette 17 is preferably inserted into the slide-in housing 15 in the position shown in Fig. 2, with the clamp 19 of the tape measure cassette being pushed onto the handle of the drill or the magazine 28.

of the plug-in component 16 is pushed onto the intermediate wall 27 of the slide-in housing 15 arranged adjacent to it. Figs. 3 and 4 show perspective views of the handle consisting of the plug-in component 16 and the slide-in housing 15 with a view of a base 33 in which an opening 34 is arranged. This makes the interior of the slide-in housing 15 accessible, so that sliding out the measuring tape cassette 17 is made easier.

A marking pen 32, in the embodiment a flat carpenter's pencil, is provided in the plug-in component 16 for marking the drilling location in preparation for the drilling work to be carried out with the drill. The pencil can be inserted into the magazine 28 from an upper side 29 of the plug-in component 16 parallel to the longitudinal axis of the magazine 28. The marking pen 32 and the insert cassette 17 are inserted into the plug-in component 16 in directions that are orthogonal to one another.

As shown in Fig. 2 to 5, a sharpening device 30 for the marking pen 32 is provided at the free end 29 of the magazine 28, which is located on the plug-in component 16 opposite the plug-in housing 15. An opening 38 of the sharpening device 30 lies in the orthogonal plane of the longitudinal axis of the magazine 28, whereby the marking pen 32 can be inserted into the sharpening device 30 essentially parallel to its rest position. On top of the sharpening device there is a rotatable ring 31 which has a central opening through which the pencil end to be sharpened can be pushed.

, the opening being adapted with respect to its cross-section to the cross-section of the marking pin 32.

Fig. 6 shows a schematic view of the clamp 19 with which the measuring tape cassette 17 is inserted and held on the housing intermediate wall 27 of the insert housing 15 at the base of the handle. While the lower leg 20b of the clamp 19 rests on the underside of the housing intermediate wall, the upper leg 20a grips around this wall 23 and rests firmly on it. The housing intermediate wall can be provided with a protruding locking lug 26 which, in the intended rest position of the measuring tape cassette 17, engages in an opening 25 in the upper clamp leg 20a of the spring clamp 19. To make it easier to remove the measuring tape cassette 17, an edge 24 of the housing wall 23 can be pulled inwards in the area of the insertion opening for the measuring tape cassette. In the locking position, when the apex of the clamp legs 20a, 20b rests against the edge of the housing wall, the measuring tape cassette protrudes slightly from the housing and can thus be easily removed by the operator.

The alternative insert part 16 shown in Fig. 8, 10 and Ii for the additional handle of the drilling machine according to Fig. 1 is equipped in its magazine 28 with slots for a metal scriber 23 and a punch 37 in addition to the marking pin 32. However, the sharpener is omitted; if necessary, a sharpener can also be provided at another location, provided there is sufficient space. In the magazine 28

As shown, the scriber 23 and the punch 37 are arranged parallel to the marking pin 32, whereby they lie essentially in the plane of the longitudinal axis of the handle or the magazine 28.
