- GAIN EL LB ARE SPAN GUIDE for discharging a PART DE R S PA NE NE EI R WERKZEUG ⁇ MACHINE
- the invention is based on a machine tool according to the preamble of claim 1.
- the user is protected from the chips generated during sawing by a cover in the form of a protective hood.
- the chips are discharged to the outside through a lateral outlet opening, whereby the outlet opening usually has a standard connection to which a vacuum cleaner or a dust bag can be connected.
- Such hand-held circular saws are often operated for convenience, however, without a vacuum cleaner or " a dust bag, with the chips arising during the sawing emerging unhindered from the outlet opening. However, this interferes with the operation of the hand-held circular saw, since the emerging chips can hit the user directly on the body. It is therefore known to provide a rotatable bend for removing the chips, so that the direction of chip removal can be influenced by a rotation of the bend. The user can then turn the elbow so that it does not get hit by the emerging chips.
- the invention encompasses the general technical teaching of providing an adjustable residue guide for removing machining residues in a machine tool, the residue guidance continuing in one position at least a portion of the machining residues within the cover.
- processing residues used in the context of the invention is to be understood generally and includes, in addition to the chips mentioned at the beginning, grinding abrasion or residues of additives, for example.
- the swivel tube preferably opens inside the cover, whereas the swivel tube opens in another swivel position outside the cover.
- the processing residues are thus removed from the swivel tube to the outside or continued within the cover.
- the remnant guide has a swivel tube which can be rotated about an axis of rotation.
- the axis of rotation is preferably angled in relation to the longitudinal axis of the swivel tube, angles between 10 ° and 50 ° being advantageous.
- a feed pipe is preferably provided for feeding the processing residues, which feed pipe opens into the swivel pipe and preferably has the same diameter as the swivel pipe.
- the axis of rotation is preferably also angled with respect to the longitudinal axis of the feed pipe, the longitudinal axes of the feed pipe on the one hand and the swivel pipe on the other hand with the rotation axis. preferably enclose the same angle.
- the axis of rotation intersects with the longitudinal axes of the feed pipe and the swivel pipe in a common intersection. This offers the advantage that the swivel tube not only runs parallel to the feed tube in a rotational position, but is aligned with it.
- the outer contours of the feed pipe and the swivel pipe are preferably circular at the joint, the feed pipe and the swivel pipe preferably having the same outer diameter at the joint. This offers the advantage that no jumps occur at the joint when the swivel tube is rotated.
- the outer contour of the swivel tube and the outer contour of the feed pipe are each spherically shaped with the same outer diameter at the joint between the swivel pipe and the feed pipe, so that the joint is spherical.
- This spherical shape illustrates the rotation function of the joint for the user.
- the outer diameter of the spherically shaped connecting pieces of the feed pipe and the swivel pipe is preferably larger than the normal outer diameter of the feed pipe or swivel pipe, in order to visually emphasize the spherical shape.
- the remnant guide has a preferably drum-shaped rotary valve which can be rotated about a predetermined axis of rotation. Depending on its rotational position, the rotary valve continues the processing residues within the cover or releases them to the outside through an outlet opening.
- the rotary slide valve has an integrated guide tube which rotates with the rotary slide valve.
- the guide tube can then deliver the machining residues in different directions depending on the rotary position of the rotary valve.
- operating elements are preferably provided, such as for example recessed grips, a knurled structure on the surface or a lever.
- the remnant guide has a connecting piece to which a dust bag or a vacuum cleaner can be connected.
- the dust bag or the vacuum cleaner hose can be fixed on the connecting piece, for example, by means of a clamp connection, in that a connecting piece of the dust bag or the vacuum cleaner hose is clipped on.
- connection piece therefore preferably has a conical shape in order to improve the clamping effect.
- connection piece here has an outer shape which tapers conically towards the distal end of the connection piece, so that the corresponding connection piece of the dust bag or the vacuum cleaner hose becomes increasingly jammed when plugged on.
- the connecting piece has an inner shape which widens conically towards the distal end of the connecting piece, so that the
- the residue guide is preferably shaped and adjustable in such a way that the residue guide has a common outer contour with the cover in one position.
- the rest guide can be adjusted continuously or in stages. With a gradual adjustment of the rest guide locking means can be provided so that the rest guide engages in one or more locking positions.
- Such latching means preferably enable at least two different latching positions, the remnant guide continuing the machining residues in the one latching position within the cover, whereas the machining residues in the other latching position are removed to the outside. In the preferred embodiment, however, several latching positions are provided so that the user can adjust the remnant guide so that the machining remnants that arise during operation are removed in the desired direction.
- a spring element can be provided which brings the remnant guide into a position in which the remnants of the machining are continued within the cover. After a dust bag or a vacuum cleaner hose has been removed, the spring element then automatically ensures that the processing residues that arise during operation are carried on within the cover in order to avoid a malfunction of the operation.

- Fig.'lc a perspective detailed view of the swivel tube from Fig. La in the unfolded
- FIG. 2a an alternative embodiment of a circular saw according to the invention with a drum-shaped rotary valve for removing sawdust, the rotary valve being closed,
- FIG. 3a shows an alternative embodiment of a circular saw according to the invention with a swivel tube in the closed state
- FIG. 3c shows a side view of the circular saw from FIG. 3a
- the circular saw shown in perspective in FIGS. 1 a to 1 c has a largely conventional design and has an electric motor which drives a saw blade 8.
- the saw blade 8 is covered by a cover 10 in the form of a protective hood in order to protect the user from the sawdust which arises during operation and to prevent injury from the saw blade 8.
- a flap 12 with an integrated swivel tube 14 is arranged on the side of the cover 10, wherein the flap 12 can be swiveled about a swivel axis 13 which runs parallel to the plane of the saw blade 8.
- the flap 12 is folded out in the state shown in FIG. 1b, so that the mouth opening of the swivel tube 14 is exposed.
- the sawdust generated during operation of the hand-held circular saw is therefore discharged laterally through the swivel tube 14.
- a dust bag or a vacuum cleaner hose can be connected to the swivel pipe 14 to receive the sawdust emerging from the swivel pipe 14.
- the swivel tube 14 therefore forms a connection piece for a dust bag or a vacuum cleaner hose in the region of its outer mouth opening, the connection piece being conical in order to achieve a firm fit of the dust bag or the ' vacuum cleaner hose on the connection piece by a clamping action.
- the inside diameter of the swivel tube 14 thus tapers inwards conically with the same cone angle with which the corresponding connecting pieces of conventional dust bags or vacuum cleaner hoses also taper, as a result of which a good press fit is achieved.
- the folding mechanism also has a spring element which automatically folds the flap 12 with the swivel tube 14 when no dust bag or vacuum cleaner hose is connected.
- the folding mechanism it is alternatively also possible for the folding mechanism to have latching elements which lock the flap 12 either in the folded state or in the unfolded state. Even without a dust bag or a vacuum cleaner hose, this advantageously enables the hand-held circular saw to be operated with the swivel tube 14 unfolded, in order to laterally remove the sawdust produced during operation.
- the flap 12 completely seals the cover 10 laterally in the closed state, so that no sawdust can escape laterally.
- the contours of the cover 10 and the flap 12 ' are also so adapted to each other that there are only minimal gaps between the cover 10 and the flap 12, so that the sawdust in the unfolded state can only escape through the swivel tube 14, whereas side currents are prevented.
- FIGS. 2a to 2c The exemplary embodiment of a circular saw according to the invention shown in FIGS. 2a to 2c largely corresponds to the exemplary embodiment described above, so that reference can be made in part to the above description. Only a partial perspective view is shown here, which shows the mechanism according to the invention.
- This hand-held circular saw also has a vertical saw blade which is driven in a conventional manner by an electric motor and is enclosed by a cover 10 'in order to protect the user from the sawdust arising during operation and to prevent injury from the saw blade.
- the sawdust within the cover 10 ' is blown upwards at a front region 16 and there it arrives in a feed pipe 18 which widens conically in the direction of flow and finally merges into a cylindrical region.
- the feed pipe 18 is open at the bottom and opens into a drum-shaped rotary valve 20 which can be rotated about an axis of rotation 21 and, depending on its rotational position, either discharges the sawdust to the outside or leads it to a rear region 22 of the cover 10 '.
- the cross Sectional shape of the feed pipe 18 should be flow-optimized and need not necessarily have a conical shape.
- the sawdust is not discharged to the outside by the rotary valve 20, but is carried further inside the cover 10 'in the rear region 22, where it finally escapes through an outlet opening on the underside of the cover 10'.
- the rotary slide valve 20 has an integrated guide tube 24 which rotates with the rotary slide valve 20 and removes the sawdust in a certain direction depending on the rotary position of the rotary slide valve 20.
- the guide tube 24 guides the chips coming from the feed tube 18 obliquely downward into the cover 10 ', where they finally escape through the outlet opening arranged on the underside of the cover 10'.
- the cover 10 ' is therefore shaped such that the mouth opening of the guide tube 24 in the position of the rotary valve 20 shown in FIG. 2a lies completely within the cover 10'.
- the cover 10 ′ therefore extends on the underside of the rotary valve 20 in the lateral direction over an angular range that is greater than the opening angle of the opening of the guide tube 24, so that the opening can be completely enclosed.
- a handle 26 is formed on the outside of the rotary valve 20, which facilitates manual rotation of the rotary valve 20.
- Handle recesses 28 and a knurled structure 30, which are integrally formed on the rotary slide 20, also serve the same purpose.
- the drum-shaped rotary slide valve 20 is rotatably supported on guide diameters which are accommodated in the cover 10 ′ by correspondingly molded bearing shells.
- locking elements are provided which allow the rotary slide valve 20 to be locked in different rotary positions.
- the guide tube 24 integrated in the rotary valve 20 forms a connecting piece to which a dust bag or a vacuum cleaner hose can be connected.
- the guide tube 24 therefore widens conically towards its mouth opening in order to achieve a press fit of the dust bag or the vacuum cleaner hose on the connecting piece.
- the exemplary embodiment of a circular saw according to the invention shown in FIGS. 3a to 3c also largely corresponds to the exemplary embodiments described above, so that reference is also made to the above description for addition. In this exemplary embodiment, too, only a partial perspective view is shown, which shows the mechanism according to the invention.
- the sawdust produced during operation of the hand-held circular saw is first blown upward in a front region 16 'of a cover 10' 'and there it arrives in a largely cylindrical feed pipe 18' which opens into a swivel pipe 32 and has an essentially horizontally extending longitudinal axis 34 ,
- the swivel tube 32 can be swiveled about a predetermined axis of rotation 36, the swivel tube 32 having a longitudinal axis 38 which, with the axis of rotation 36, forms the same angle as the longitudinal axis 34 of the feed pipe 18 '.
- This geometric arrangement enables the swivel tube 32 to be aligned with the feed pipe 18 'in the rotational position shown in FIG. 3b, so that the sawdust emerges from the swivel tube 32 without deflection.
- the feed pipe 18' and the swivel pipe 32 have spherically shaped connecting pieces 40 and 42, where at the connectors 40, .42 have the same outer diameter.
- this offers the advantage that the outer contours of the feed pipe 18 'and the swivel pipe 32 merge seamlessly into one another, which contributes to an optically appealing overall impression.
- the swivel tube 32 opens into a connecting pipe 43 in the cover 10 ′′, so that the chips are carried on within the cover 10 ′′ and finally through an outlet opening on the underside the cover 10 '' escape.
- FIGS. 4a to 4d The exemplary embodiment of a circular saw according to the invention shown in FIGS. 4a to 4d largely corresponds to the exemplary embodiment described above and shown in FIGS. 3a to 3d, so that corresponding reference numerals are used in the following for corresponding components and to avoid repetition of the above description is referred.
- the peculiarity of this exemplary embodiment is that the feed pipe 18 ′′ and the swivel pipe 32 ′ have no spherical thickening at the joint, which gives a different visual impression.
