Hand-ripper with a reset spring device

The invention relates to a hand-cutting machine, in particular a sawing machine, with a drive assembly, which has a tool holder for a disc-like cutting tool, in particular a saw blade, and a drive motor for rotationally driving the tool holder, and with a guide device with a guide surface on a substrate along is feasible and on which the drive assembly is pivotally supported by a Tiefeneinstelllagers about a Tiefenstellachse between an upper and a lower cutting depth position, wherein the tool holder is closer to the guide surface than in the upper depth of cut position in the lower depth position, so that the cutting tool further ahead of the Guide surface protrudes than in the upper depth of cut position, wherein the hand-separating a relative to the drive assembly between an open position and a closed position pivotally mounted, hood-like covering for covering the separating tool, which in the open position for introducing a separating cut into a workpiece releases a section projecting in front of the guide surface of the separating tool and in the closed position covers the separating tool.

A hand-cutting machine of this type is usually a so-called pendulum hood saw, the saw blade is covered by the pendulum hood when not in use. The covering assumes the closed position. This protects the user. The user can not grasp the possibly rotating cutting tool and injure himself. Therefore, the cutting tool can readily protrude permanently before the guide surface, since it is hidden when not in use by the pendulum hood. However, for some modes, the handling of Tiefeneinstelleinrichtung is relatively complicated, that is, the operator must first take the guide means or at least ensure that it is oriented down, on the other hand, anyway, the drive assembly also touch to adjust the respective depth of cut.

It is therefore the object of the present invention to improve the handling of a manual cutting machine of the type mentioned.

To achieve the object, it is provided in a manual cutting machine of the type mentioned at the outset that the drive assembly is acted upon by a restoring spring device in the direction of the upper cutting depth position.

The advantage of this construction is that the manual cutting machine automatically adjusts itself in the direction of the upper cutting depth position. So if, for example, a depth adjustment is provided which allows fixing of the drive assembly with respect to the guide means by the operator to set in this way a depth of cut, the operator need only solve this fixation, whereupon then the drive assembly, so to speak automatically, namely by the force the return spring device, adjusted in the direction of the upper depth of cut position. The operation and handling is very convenient and easy.

The return spring device allows the use of the hand-cutting machine both as a conventional pendulum hood saw and as a submersible saw.

In the closed position, the covering device covers the separating tool completely or at least partially. In any case, it is preferably provided that, in the closed position, the covering device covers a furthest removed region or apex region of the separating tool in front of the guide surface. It is preferably provided that the cover device is arranged in the closed position below the guide surface of the guide device.

It is preferred if the manual separating machine has a spring deactivating device for at least partially deactivating the restoring spring device, wherein the restoring spring device does not act on the drive assembly in this deactivated state or to a lesser extent in the direction of the upper cutting depth position. For example, the return spring device is held in this deactivation position between spring-holding elements, so to speak clamped or clamped, for example, which is fixedly connected to the drive assembly or the guide device or connectable. For example, one of the spring-holding elements permanently fixed to the drive assembly or the guide means may be arranged, while the other spring-holding element between the reset spring device releasing activation position in which the return spring means acts on the drive assembly in the direction of the upper depth of cut position, and a Deactivated deactivation position, in which the return spring means is held between the spring-holding elements. For example, it is possible for the spring deactivator to include a clamp screw, a clamp body, a clamp lever, a detent, a pawl, or the like to hold the return spring means in the at least partially deactivated state. One of the aforementioned spring-holding elements is thus preferably mounted between a release position releasing the return spring device and a blocking position which at least partially holds the return spring device adjustable on the drive assembly or the guide device.

The spring deactivation device expediently forms a fixed or integral part of the manual cutting machine. It is expediently provided that the spring deactivating device can not be detached from the manual separating machine during normal use and / or that the spring deactivating device is advantageously not designed as an additional adapter. The spring-deactivating device is expediently without tools and / or actuating element actuated by a permanently on board the hand-separating machine present Be.

Appropriately, it is provided that the spring deactivation device remains in the deactivated state of the return spring device on board the hand-ripper. The spring deactivation device thus always or permanently remains on board the manual separating machine, so that it can be used by the operator at any time.

An advantageous embodiment provides that the covering device is spring-loaded in the direction of the closed position. For example, a corresponding closing spring is provided, which is stretched during the adjustment of the cover from the closed position to the open position and thus loaded the cover in the direction of the closed position.

An actuating device for manually adjusting the covering device from the closed position to the open position is advantageously provided. The actuating device is expediently arranged on the drive assembly. Preferably, the actuator comprises an actuator, beispielswei se an actuating lever or the like, which is operable by the operator when gripping the drive assembly. Preferably, the construction is so erfof fen that the operator, so to speak, manually actuates the cover from the closed position to the open position, but in the opposite direction, the spring load acts. A preferred embodiment provides that the spring arrangement is integrated into the actuating device. For example, the aforementioned actuating element may be spring-loaded in a position corresponding to the closed position of the covering device.

Preferably, the hand-ripper has a depth adjusting device for setting a respective cutting depth position.

An advantageous variant provides that the restoring spring device is arranged on the depth adjustment device. It is also possible that the return Stell-spring device is integrated into the Tiefeneinstelleinrichtung or forms a part of the Tiefeneinstelleinrichtung.

A further variant of the invention provides that the manual cutting machine has a guide arrangement for guiding the pivoting movement of the drive assembly about the Tiefeneinstellachse relative to the guide device. The guide arrangement has a distance to the Tiefeneinstelllager. It is advantageous if the return spring device is arranged on the guide arrangement or is integrated in this. It can also form part of the leadership arrangement.

The guide assembly and depth adjuster may be one or the same assembly or disposed thereon. In this respect, it is therefore also possible for the return spring device to be arranged on the depth adjustment device and at the same time for the guide arrangement.

The guide arrangement expediently has guide elements which are guided against each other. Conveniently, the return spring device is guided on at least one of the guide elements.

Preferably, the guide elements comprise a guide projection and a guide receptacle, in which engages the guide projection. The return spring device is expediently arranged between the guide projection and the guide receptacle. For example, the guide projection is rod-shaped and penetrates or penetrates a spring of the return spring device. The spring is advantageously arranged in the guide receptacle.

It is possible that the restoring spring device is advantageously received and / or guided in a guide receptacle, in particular for guiding the adjusting body. Furthermore, it is additionally or alternatively possible that the return spring device is guided on a guide projection and / or on the adjusting body. For example, the guide projection or the adjusting body penetrates or passes through the return spring device, in particular a helical spring. It should be mentioned at this point that the return spring device does not necessarily have to be arranged on or at the depth adjustment device. The return spring device can also be arranged away from the depth adjustment device or next to the depth adjustment device.

A preferred embodiment of the invention provides that the depth adjustment device or the guide arrangement form or comprise the spring deactivation device.

A preferred embodiment of the invention provides that the Tiefeneinstelleinrichtung for adjusting the respective cutting depth position associated with the guide means Tiefeneinstellelement and connected to the drive assembly drive Tiefeneinstellelement, which is adjusted in the adjustment of the cutting depth position relative to the guide Tiefeneinstellelement, and a at least one setting functionality providing adjusting body, and that the adjusting body is movably mounted with respect to the guide Tiefeneinstellelements and the drive Tiefeneinstellelements and by means of a drive-fastening device to or with the drive Tiefeneinstellelement and by means of a guide-fastening device on the guide Tiefeneinstellelement is releasably attachable.

The guide Tiefeneinstellelement can for example form a part of the guide means, so be fixed to the guide means. At this point it should be noted that the guide device can also be multi-part, so may include a drive carrier for the drive assembly explained later. The guide Tiefeneinstellelement can be arranged for example on the drive carrier. The drive Tiefeneinstellelement example, fixed to the drive assembly, for example, a housing thereof, arranged.

The guide Tiefeneinstellelement can form or have a stop for the drive assembly. The drive depth adjustment element can also be For example, form a stop for the guide device, for example, the aforementioned drive carrier or have.

The basic idea is that the adjusting body once has a relation to the drive assembly, once a reference to the guide device. The adjusting body can thus be connected once with the drive assembly, at another time with the guide means and also with both the guide means and the drive assembly. As a result, the adjustment body can realize a plurality of completely different adjustment functionalities. The following explains some setting functions that can be used individually or in any combination with each other.

The at least one setting functionality includes, for example, a stop function. The adjusting body preferably serves as a stop element for abutting the drive assembly in at least one cutting depth position. In this case, it is possible, for example, for the adjusting body to be fastened to the guide depth adjusting element and for the drive module to abut against the adjusting body which is stationary relative to the guide device. But it is also possible that the adjusting body is fixedly connected to the drive assembly and is moved with it, so to speak, where it strikes in its function as a stopper body on a counter-stop element, which in turn is fixedly secured to the guide means.

Another advantageous setting functionality includes a display function. It is preferable if the adjusting body serves as a display element for indicating a respective cutting depth position. It is possible that the display element, for example, carries an index, which is on a display scale, which is stationary relative to the drive assembly or the guide means is moved. For example, a corresponding scale can be provided on the guide Tiefeneinstellelement or the drive Tiefeneinstellelement on which the adjusting body or the index of the adjusting body is moved past to indicate in this way a respective depth of cut. It is preferred that an indicator scale is provided on the adjusting body, which is mounted on a relative to the Füh- tion device or relative to the drive assembly stationary index is moved past. When the adjusting body is directly displaced with respect to a corresponding index, indexable indexes, for example, are not necessary in the manner of riders. Thus, for example, an index or a display scale can be provided on the adjusting body.

Another setting functionality is for example a fixing function. It is preferred if the adjusting body is designed as a fixing element for fixing the drive assembly with respect to the guide means in at least one cutting depth position or serves. For example, it is possible that, in this case, the guide fixing means and the drive fixing means are connected to the adjusting body to thereby fix the driving assembly with respect to the guide means in a predetermined cutting depth position.

A preferred embodiment provides that the depth adjustment device has or forms a fixing device for fixing the drive assembly with respect to the guide device in at least one cutting depth position. This functionality is preferably realized in connection with the adjusting body. But it is also possible that the fixing function is realized independently of the setting body. The adjusting body can for example serve as a stop element and the fixing function can additionally be realized, for example by providing a clamping device or latching device or locking device for clamping, latching or locking the drive assembly relative to the guide device away from the adjusting body.

When the depth adjusting member and the adjusting body are connected to each other by the respective fastening means, they are advantageously fixed relative to each other with respect to at least one degree of freedom of movement.

The adjusting body expediently forms a fixing body for fixing the drive assembly with respect to the guide device. For example, forms or the fixing body comprises a positive locking body, which allows a positive fit, and / or a clamping body which is clamped or actively acts in the sense of clamping. For example, the adjusting body may include a clamping pliers or the like.

An advantageous embodiment of the invention provides that the drive-fastening device or the guide-fastening device or both has a locking device for locking the adjusting body with the respective Tiefeneinstellelement. At least one of the aforementioned fastening devices may also comprise a clamping device for clamping the adjusting body with the respective Tiefeneinstellelement (guide Tiefeneinstellelement or drive Tiefeneinstellelement).

Furthermore, it is possible for a frictional engagement surface to be provided on a retaining element of the drive fastening device or the guide fastening device, wherein the frictional engagement surface serves for frictionally holding the adjustment body. A friction frictional surface is also advantageous in this context on the adjusting body. The frictional engagement surface may include, for example, a rubber coating or the like.

Preference is given to a form-fitting hold which the respective fastening device and the adjusting element realize with one another. It is expediently provided that the drive fastening device or the guide fastening device or both and the adjusting body have mutually matching form-fitting contours and Gegenformschlusskonturen. For example, positive locking projections are provided in the fastening device, which can engage positively in form-fitting receptacles of the adjusting body.

An advantageous configuration provides that the form-fitting contours or counter-form-fit contours or both have a row of teeth or another arrangement of form-fit projections or form-fit receptacles arranged side by side in a row direction, the different cut edges. fenpositionen are assigned. For example, two or more form-fitting projections or form-fitting receptacles are arranged next to one another. It is particularly preferred if at least one, preferably two rows of teeth are or are provided, which are engageable in different depth of cut positions in engagement with a counter-tooth or with each other. Due to the plurality of teeth, which are each in engagement with each other, a particularly firm hold in the respective cutting depth position is given.

A preferred embodiment provides that the drive fastening device or guide fastening device or both are spring-loaded in the direction of a holding position holding the adjusting body. The fastening device thus has a holding element which is loaded by a spring or spring arrangement in the direction of the holding position. Thus, the operator only needs to be active in one direction, i. So bring the fastener from the holding position in a release position, so that the adjusting body is released. In the opposite direction then works, for example, a spring, in particular a compression spring or a tension spring, which loads the respective holding element of the drive-fastening device or the guide-fastening device in the direction of the holding position.

Appropriately, it is provided that the holding element by an adjustment of the drive assembly and the guide means about the Tiefeneinstel- salmon relative to each other in the direction of a release body releasing release position is deflectable, ie, for example, a corresponding operating contour, for example, an actuating slope has. Preferably, therefore, a holding element is provided, which is for example by an adjustment or pivoting of the drive assembly about the Tiefeneinstellachse to the guide device in a release position or adjustable in the release position adjustable, for example, is swung, and thereby releases the adjusting body or receives a bias to to hold the adjusting body again. In this case, it is preferably provided that then the retaining element is in turn acted upon by the spring or spring arrangement in the holding position to hold the adjusting body. So the drive assembly, for example, in the lower Cut depth position can be fixed. Furthermore, it is possible in this way to lock the adjusting element, for example, with the holding element or to jam, so that the setting element, for example, stationary with the guide means, for example, the drive carrier, or the drive assembly is connected.

A retaining element of the drive fastening device or the guide fastening device is expediently movably mounted on the drive assembly or the guide device between a holding position holding the adjusting body and a release position releasing the adjusting body. However, it is also possible that a retaining element of the drive fastening device or the guide fastening device is movably mounted on the adjusting body and, for example, moved away in the release position of the associated drive Tiefeneinstellelement or Fuhr- Tiefeneinstellelement, in the holding position with this is in contact, for example, positively engages in this or frictionally engages this.

A retaining element of the respective fastening device, on which, for example, form-fitting contours, frictional surfaces or the like are provided, which is thus provided for holding the adjusting body, is expediently pivotably mounted on the drive fastening device or the guide fastening device. For example, the holding element is pivotally mounted on the guide device or the drive assembly or the adjustment. Such a holding element is particularly easy to operate. But it is also possible that a holding element of the drive-fastening device or the guide-fastening device is slidably mounted on the drive module or the guide device or the adjusting body.

It is preferred if the drive-fastening device or the guide-fastening device or both a hook or a holding pawl to Has engagement in the adjusting body. The hook or the retaining pawl is preferably spring-loaded.

The drive fastening device and / or the guide fastening device preferably have a holding element which has a holding arm and an angular, for example, approximately right-angled, actuating arm. The holding arm is provided for contact with the adjusting body. For example, the holding arm has a frictional surface or clamping surface or form-fit contours for holding the adjusting body. The actuator arm is angled from the support arm and can be easily grasped by the operator.

It is expedient if an actuating element for manually actuating the guide-fastening device or the drive-fastening device or both, for example, a corresponding handle portion of the aforementioned actuating arm, is arranged in the working direction behind the hand-ripper. Of course, the actuator may also be provided above, for example at the top of the drive assembly.

It is advantageous if an actuating element is arranged ergonomically at an area of the drive assembly furthest away from the guide surface, for example in the region of an upper apex region of the drive assembly, for example a cover hood for the separating tool.

By means of the actuating element, an operator can, for example, move the guide fastening devices and / or the drive fastening device from a fixing position fixing the adjusting body with the respective depth setting element into a release position, in which the adjusting body is movable relative to the respective depth setting element, and / or vice versa from the release position in the fixing position.

It is expedient if the drive-fastening device and / or the guide-fastening device is loaded in the direction of the fixing position by a spring or spring arrangement and the operator the respective Befestigungsseinrich- tion must actively operate only in the direction of the release position. For example, the respective fastening device forms a latching device, which is loaded in the direction of the fixing position by the spring or spring arrangement in the direction of a setting element with the drive depth adjustment element or the guide depth adjustment element.

A manual actuating element is expediently assigned an abutment element, for example an arm, to which the operator can move the actuating element. For example, the operator may grip the actuator and the abutment member in the manner of a pair of pliers or scissors.

It is advantageous if a guide arrangement for guiding the drive assembly is provided at a distance to the Tiefeneinstelllager to guide the drive assembly relative to the guide means in the adjustment about the Tiefeneinstellachse.

It is possible that the drive assembly is guided relative to the guide device with respect to the Tiefeneinstellachse off the Tiefeneinstelleinrichtung. For this purpose, a separate guide arrangement with, for example, a guide projection on the drive assembly is then provided, for example, which dips into a guide receptacle of the guide device. It can also be provided, for example, arcuate guide surfaces or the like.

A preferred embodiment of the invention provides that the depth adjustment device has or forms a guide arrangement for guiding the pivoting movement of the drive assembly about the depth adjustment axis relative to the guide device. Thus, therefore, the depth adjustment contributes to the leadership of the drive assembly with respect to the guide device.

The guide components of this guide arrangement can be provided independently of the adjusting body, for example comprising interengaging guide projections and guide seats or corresponding guide slots or surfaces. However, it is preferred if the adjusting body forms a guide component of this guide arrangement. An expedient variant of the invention provides that the guide depth adjustment element and / or the drive depth adjustment element or both have or form a guide for the adjustment body. For example, the respective depth adjusting element has a guide receptacle for receiving the adjusting body or a guide projection for engaging in the adjusting body. Corresponding components are preferably provided on the adjusting body, for example a guide receptacle in which a guide projection of the depth adjusting element engages. When the adjusting body engages in a guide receptacle of a respective Tiefeneinstellelements, under certain circumstances, no special measures are provided. A guide receptacle is designed, for example, as a guide channel.

Conveniently, a guide receptacle or a guide projection, which is provided on the adjusting body or on a respective Tiefeneinstellelement, for example the drive Tiefeneinstellelement or the guide Tiefeneinstellelement, an arcuate course. The curvature or arc extends at a predetermined radius about the depth adjustment axis.

Appropriately, it is provided that the guide body is mounted in the respective guide receiving slide-movable. The guide body and the sliding receptacle advantageously have an arcuate course.

It is preferred if the adjusting body has an arcuate course and / or is rod-shaped. For example, a curvature or an arc shape of the adjusting body extends around the depth adjusting axis with a predetermined radius.

The adjusting body preferably has an elongated shape.

The adjusting body extends, for example, along a path running around the depth adjusting axis. The adjusting body is preferably received against rotation in a respective guide. For example, the adjusting body has a polygonal, in particular rectangular cross-section, which corresponds to a corresponding rotationally receiving inner contour of the guide.

It is advantageously provided that the adjusting body forms a holder or guide for the return spring device. For example, the restoring spring device dips into a receptacle of the adjusting body.

An advantageous variant of the invention provides that the adjusting body forms a spring retaining element of the spring deactivating device. For example, the return spring device can be determined based on the setting in a predetermined deactivation position, so that it does not act on the drive assembly or to a lesser extent in the direction of the upper depth of cut position. This is possible, for example, by virtue of the fact that the adjusting body is fixed in place by means of the drive fastening device or the guide fastening device between the adjusting body and another spring retaining element, which is preferably formed by the drive depth adjusting element or the guide depth adjusting element kept inactive.

A self-contained invention, it is when in a

Hand-separating machine according to the preamble of claim 1 is provided a latching device for locking the drive assembly with the guide means in at least one cutting depth position. The latching device is formed for example by the Tiefeneinstelleinrichtung or is arranged thereon.

The manual cutting machine is preferably a so-called pendulum hood saw. The hand-cutting machine can also be a so-called dip saw. Furthermore, however, the approach according to the invention can also be implemented without difficulty in the case of cut-off grinders. It is preferred if the

Hand-cutting machine according to the invention can be used both as a pendulum hood saw and as a dip saw.

The guide device comprises, for example, a so-called saw table, which can be guided along the workpiece or a guide rail resting on the workpiece by the operator. The depth adjustment bearing allows you to set the desired depth of cut.

A preferred embodiment of the invention provides that the Tiefeneinstel- salmon in the working direction is forward. It is also conceivable, however, for the depth-adjusting axle to be arranged at the rear in the working direction.

It is preferably provided that the guide means comprises a drive carrier on which the drive assembly is pivotally mounted about the Tiefeneinstellachse based on the Tiefeneinstelllagers.

It would be possible that the drive assembly is fixedly arranged on the drive carrier. Appropriately, the drive carrier is relative to a guide surface having guide element, in particular a guide plate, pivotally mounted about a miter axis based on a miter bearing assembly. The miter axis expediently runs parallel to the working direction.

The Tiefeneinstelleinrichtung is advantageously provided between the drive carrier and the drive assembly. Between the drive carrier and the drive assembly, for example, the return spring device is arranged.

The drive motor of the drive assembly is expediently arranged in a machine housing.

At the drive assembly, for example, the machine housing, at least one handle for gripping and / or guiding the hand-separating machine is expediently provided or arranged. Preferably, several handles or handle portion are present.

Hand-cutting machine in perspective obliquely from above,

Figure 10 is a perspective oblique view of the hand-ripper together with a guide rail, and

Figure 1 1, the hand-cutting machine when cutting into a workpiece from the side.

A manual cutting machine 10 according to the drawing is designed as a sawing machine. A drive assembly 1 1 has a drive motor 12 for rotationally driving a tool holder 13 about a rotation axis D. The drive assembly 1 1 comprises a machine housing 35 which receives the drive motor 12. At the tool holder 13 is a disc-shaped separating tool, for example, a blade or a saw blade, releasably fastened. The cutting tool 14 is bolted to the tool holder 1 3, for example, fixed by a bayonet connection or the like. Thus, therefore, bayonet connection means, screw connection means, a retaining screw or the like for fastening the separating tool 14 to the tool holder 13 are provided on the tool holder 13.

The drive assembly 1 1 can be grasped and guided on a handle 15 by an operator. On the handle 15, a switch 16 for switching the drive motor 12 is arranged, in particular also to the speed setting. The drive motor 12 is an electric motor. It can be powered, for example, via a not shown in the drawing power cord. However, a local power supply on board is particularly preferred

Hand-separating machine 10, for example, based on a battery or other energy storage 17th

The handle 15 expediently extends in the working direction A of the manual cutting machine 10, with which it can be guided, for example, along a workpiece such as a guide rail 90 for introducing a separating cut T into the workpiece W. The manual ripper 10 has a fixed cover 18 and a movable cover 19 for covering and covering the separating tool 14. For example, the fixed cover 18 forms a part of the machine housing 35 or is arranged at this stationary. The fixed cover 18 is always located at the top of the workpiece W or the top of the guide rail 90 during operation of the manual ripper 10. The movable cover 19, however, covers, so to speak, the underside or the free side of the cutting tool 14, especially if this off of the workpiece B is located. Thus, when the hand-ripper 10 is not in use, the cutting tool 14 is usually completely disposed inside the cover 18 and the cover 19, so that the operator can not be injured, even if the cutting tool 14 is still rotating.

The manual cutting machine 10 has a guide device 20 with a guide element 21, for example a guide plate. The guide element 21 is designed, for example, as a saw table. The drive assembly 1 1 is pivotably mounted on the guide device 20 by means of a depth adjustment bearing 36 about a depth adjustment axis TA. Thus, a depth of cut ST of the parting tool 14 into the workpiece W can be changed. A pivoting of the drive assembly 1 1 relative to the guide device 20 about the depth axis TA is indicated by an arrow P in FIG.

The depth adjustment axis TA is located in the working direction A at the front, close to a front side 24 of the guide device 20. The saw blade or cutting tool 14, however, is arranged on the right in the direction of A side 22 or longitudinal side of the guide device 20 or the guide member 21. The drive assembly 1 1 is located between the side 22 and a left in the working direction A side 23 of the guide member 21 or the guide device 20th

The parting tool 14 protrudes partially toward an upper side 26 of the guide element 21, partially in front of a guide surface 27 on the underside of the guide element 21, namely, when the drive assembly 1 1 is made of the in Figure 1 shown upper depth of cut position SO is at least partially displaced or pivoted in the direction of a lower, for example, the lowest depth of cut position SU. It is preferably provided that the separating tool 14 does not protrude in front of the guide surface 27 in the upper depth of cut position SO.

A handle 28, for example, projecting in front of an upper side of the guide member 20 and preferably is like a gag, facilitates the guidance and handling of the hand-ripper 10. The handle 28 is arranged in the working direction A in front of the handle 15.

Expediently parallel to the working direction A, in a longitudinal direction L of the guide rail 90, a longitudinal guide receptacle 33 for longitudinal guidance on a longitudinal guide projection 93 of the guide rail 90 and / or extends between the front side 24 and a rear or rear side 25 of the guide element 21 a rear engagement receptacle 34 for rear engagement by a Hintergreifvorsprung 94 of the guide rail 90. The longitudinal guide projection 93 and the Hintergreifvorsprung 94 are arranged for example on an upper-side guide surface 92 of a rail body 91 of the guide rail 90. On the longitudinal guide projection 93, the guide device 21 in the working direction A and thus the longitudinal direction L of the guide rail 90 can be guided. This can be placed with its bottom 95, for example, on the workpiece W, so that accurate and straight saw cuts or cuts are possible in this way. The rear engagement projection 94 and the rear engagement reception 34 ensure that the guide rail 90 is held on the guide device 20 transversely to the longitudinal direction L, so that the entire unit comprising the manual separation machine 10 and the guide rail 90 is taken by one operator from the workpiece W to another workpiece can, without this two components takes.

The drive assembly 1 1 is with respect to the guide member 21 about a miter axis GA, which is parallel to the working direction A, pivotally mounted (corresponding to an arrow G in Figure 10). For example, a drive carrier 40 is based on a miter bearing arrangement 30 on the guide device 20 to the Miter axis A pivotally mounted. Between the guide member 21 and the drive carrier 40, a miter bearing assembly 30 is provided. The miter bearing arrangement 30 is located close to the tool holder 13, that is to say on the right-hand side 22 in the working direction A or on the longitudinal side.

The miter bearing arrangement 30 comprises a front miter bearing 31 in the working direction A and a miter bearing 32 behind a working direction A.

The Tiefeneinstelllager 36 is arranged in the direction of A in front of the front miter 31. As a result, an exit region of the separating tool 14 from the workpiece W can be viewed particularly favorably.

The miter bearings 31, 32 comprise bearing elements 37, 38 which project upwardly in front of the guide element 21. At these abutment portions 41, 42 of the drive carrier 40 are pivotally mounted. The bearing elements 37, 38 and the abutment portions 41, 42 are for example plate-like. On the basis of fixing elements, such as clamping screws or the like, in particular only a single clamping screw 39, the abutment portions 41, 42 can be clamped to the bearing elements 37, 38, so that a respective miter position or miter pitch position of the cutting tool 14 relative to the guide surface 27 can be fixed. Often, the cutting tool 14 will be perpendicular to the guide surface 27, as regularly shown in the drawing.

The bearing element 37 preferably projects through a passage opening 45 of the drive carrier 40.

In front of the front miter 31 is a support arm 46 of the drive carrier 40, on which a support arm 29 of the drive assembly 1 1 is mounted. From the support arm 46 are from the side bearing projections 47 which engage in corresponding bearing receptacles of the support arm 29. The bearing projections 47 extend along the Tiefeneinstellachse TA. Consequently, therefore, the support arm 29 and thus the drive assembly 1 1 pivots on the bearing projections 47 of the Tiefeneinstellachse 36 about the Tiefeneinstellachse TA. At a longitudinal distance to the Tiefeneinstelllager 36 a Tiefeneinstelleinrichtung 50 is provided. With the Tiefeneinstelleinrichtung 50 several functions can be realized, namely, for example, a display of a respective cutting depth position and / or a stop function with which the drive assembly 1 1 strikes in a preferably adjustable depth of cut position with respect to the guide device 20 and / or a fixing function to the drive assembly 1 1 in a predetermined or adjustable cutting depth position ST with respect to the guide device 20 to fix.

The depth adjustment device 50 comprises an adjustment body 51, which is movably mounted with respect to a guide Tiefeneinstellelements 70 fixed with respect to the guide device 20 and a drive Tiefeneinstellelements 60 stationary relative to the drive assembly 11. The guide Tiefeneinstellelement 70 is provided for example on the drive carrier 40.

The adjusting body 51 is rod-shaped, but not straight, but bent. It has a curvature which has a fixed radius about the depth adjustment axis TA, and therefore extends in an arc around the depth adjustment axis TA.

The adjusting body 51 is slidably received in a guide receptacle 72 of the guide Tiefeneinstellelements 70. The guide receptacle 72 has an arc-shaped course corresponding to the curvature or the arc shape of the adjusting 51st Thus, the adjusting body 51 can be moved in the guide receptacle 72 about a curved path KB whose curvature or radius with respect to the Tiefeneinstellachse TA is constant.

The guide receptacle 72 comprises a guide wall 71 radially outward with respect to the cam track KB and with respect to the cam track radially inner support contour 73. On the guide wall 71 and the support contour 73, which advantageously form components of the drive carrier 40, longitudinal sides 54, 53 of the adjusting 51 are supported , The longitudinal side 54 is smooth, while the longitudinal side 53, as will become clear later, has a toothing 58. The longitudinal sides 53, 54 have a curved course.

Between the lower longitudinal end region 55 and an upper longitudinal end region 56 of the adjusting body 51 extends a guide receptacle 52 into which the drive guide element 60 with a guide projection 62 dips.

The longitudinal sides 54, 53 extend between the longitudinal end regions 55, 56 of the adjusting body 51. The adjusting body 51 is for example approximately rectangular or square in cross section. However, the adjusting body 51 could also have other cross-sectional contours, for example also a circular cross-sectional contour.

Sides between the narrow sides or longitudinal sides 53, 54 extending unspecified longitudinal sides of the adjusting 51 are based on the one hand on a side wall 48 of the machine housing 35, on the other hand on a support wall 44 of the drive carrier 40 from. The support wall 44 is located between the guide wall 71 and the support contour 73 and limits the guide seat 72 laterally (FIGS. 8, 9).

A longitudinal end region 55 of the adjusting body 51 facing the guide device 20 can abut against a base 74 of the guide receptacle 72 when it is adjusted to its lower position shown in FIGS. 3 and 4.

The adjusting body 51 is movably mounted on the drive assembly 1 1 with respect to the drive Tiefeneinstellelements 60. The guide projection 62 projects in front of a head 61 of the drive depth adjusting member 60. The head 61 of the drive guide member 60 is fixed, for example, on the machine housing 35, conveniently in the vicinity of the handle 15, fixed. The guide projection 62 has a rod-like shape and protrudes toward the guide device 20 in front of the head 61.

Furthermore, it is possible that on the drive assembly 1 1 further guide components, for example, a guide slot 63 and one of these opposite overlying guide wall 64 are provided, between which the adjusting body 51 is slidingly adjustable. The guide wall 64 and the guide slot 63, which is also configured, for example, in the manner of a wall, define an arcuate guide receptacle 63a for the adjusting body 51.

The guide projection 62 has an arcuate course as well as the adjusting body 51 and the guide receptacle 72 and the guide receptacle 52 and the guide receptacle 63a.

Thus, therefore, these guide components in the sense of a guide relative to each other or interact with each other, in particular engage each other. As a result, a guide arrangement 75 is provided as a whole, which guides the drive assembly 51 at a distance from the depth adjustment bearing 36 when pivoting about the depth adjustment axis TA.

Between the guide projection 62 and the guide seat 51 of the adjusting 51, a gap or distance is present. At this distance, a return spring means 65 is arranged with a return spring 66. The return spring 66 is a coil spring. The guide projection penetrates the restoring spring 66. An outer circumference of the restoring spring 66 bears, for example, against the inner circumference of the guide seat 52. The return spring 66 is expediently supported with its one longitudinal end on a provided at the longitudinal end portion 56 bottom 59 of the guide receptacle 52, with its other longitudinal end on the head 61 of the drive Tiefeneinstellelements 60 from. Thus, the return spring device 65 loads the drive assembly 1 1 in the direction of the upper depth of cut position SO.

This spring effect could in principle be provided permanently, but in the present case can be deactivated. In this context, the adjusting body 51 plays an advantageous and / or essential role.

The adjusting body 51 is selectively detachably connectable to the guide device 20, in particular its drive carrier 40, and to the drive assembly 1 1, for which a guide fastener 80 and a drive fastener 100 are provided.

The drive fastening device 80 comprises a holding element 81, which has a form-fitting projection 82 for engagement in a form-fitting receptacle 57a of the setting body 51. The positive locking receptacle 57 is arranged, for example, on the longitudinal end region 56 of the adjusting body 51, in any case on a section of the adjusting body 51 projecting far in front of the guide device 20.

The form-fitting projection 82 is provided, for example, on a retaining arm 88 of the retaining element 81. From the holding arm 81 is an actuating arm 83 from. The operating arm 83 is arranged, for example, so that it can be easily grasped by the operator. For example, the actuating arm 83 projects toward the handle 15. The holding element 81 is pivotable about a pivot axis by means of a pivot bearing 84, so that it can be adjusted between a holding position (shown in solid lines) and a release position (shown in dashed lines). The holding element 81 strikes in the release position, for example, on a stop 85. For example, the actuating arm 83 abuts against the stop 85, which is plate-like, for example. In the holding position, the form-locking projection 82 or the holding arm 88 engages in the form-fitting receptacle 57 a on the adjusting body 51, so that it is connected to the drive assembly 1 1.

The holding element 81 is acted upon by a spring arrangement 87 in the direction of the holding position. When the holding member 81 is moved to the release position, the spring assembly 87 is tensioned. For example, an actuating projection 86 is provided, which acts on the spring arrangement 87. The spring assembly 87 is supported on the one hand on the actuating projection 86, on the other hand on a holder 89, for example a receiving chamber, for the spring assembly 87 from. The holder 89 is provided fixed to the drive assembly 1 1.

Due to the spring load on the basis of the spring arrangement 87, the holding element 81 is designed in the manner of a latching device or forms a latching element. At the upper longitudinal end portion 55 of the adjusting 51 is an actuating contour 57, for example, an actuating bevel provided to deflect the support member 81 in the direction of the release position, wherein the adjusting 51 can then slide past the support arm 88 until it with its form-fitting projection 82 in the form-fitting receptacle 57a, so to speak. Then, the restoring spring device 85 between, on the one hand, the drive depth adjustment element 60 and, on the other hand, the adjustment body 51, which is no longer adjustable or fixed relative to the drive depth adjustment element 60, is so to speak firmly blocked and thus ineffective or deactivated. The operator can thus set a diving depth or cutting depth position ST without the restoring spring device 85 acting in the direction of the upper cutting depth position SO.

The adjusting body 51 and the drive Tiefeneinstellelements 60 thus form spring-holding elements for holding the return spring means 65 in a deactivation vierungsposition. The depth adjustment device 50 thus forms a spring deactivation device 76 in this function.

Structurally, the arrangement of the return spring device 65 in the Tiefeneinstelleinrichtung 50 has the advantage that as few components are necessary and the space is used optimally. For example, the return spring device 65 is not or barely in the way of suction of chips or the like.

It should be noted that, of course, at a different point a return spring device would be possible, which is exemplified by the reference shown in Figure 5 return spring means 165. This relies, for example, directly on the guide member 20 and the drive assembly 1 1 from. An additional guide, for example a guide sleeve or a guide rod, for the return spring means 165 is readily possible (not shown).

The adjusting body 51 is firmly connected to the drive assembly 1 1 on the basis of the drive-fastening device 80 and makes in with the drive assembly 1 1 connected state whose pivotal movements about the Tiefeneinstellachse TA with. Thus, for example, a display scale 67 on the adjusting body 61 relative to an index 68 for use of the hand-ripper 10 without the guide rail 90 or a graded index 69 for the use of

Hand-separating machine 10 are adjusted with the guide rail 90. The indices 68, 69, together with the display scale 67, indicate the respective cutting depth position ST of the separating tool 14 with respect to the guide surface 27. As I said, while the return spring device 65 is deactivated, so does not bother the depth adjustment.

On the basis of the guide-fastening device 100, the adjusting body 51 with respect to the guide device 20, more precisely with respect to the drive carrier 40, fixed in place. This fixation or fixing is solvable. A retaining element 101 of the guide fastening device, like the retaining element 81, can engage from a holding position which positively holds the adjusting body 51, in which a toothing 102 engages a retaining arm 108 of the retaining element 101 in a complementary toothing 58 on the adjusting body 51, in particular its longitudinal side 53 a release position (indicated by an arrow P1 in Figure 6) are adjusted, in which the teeth 58, 102 do not mesh. Then the adjusting member 51 is adjustable relative to the guide device 20, namely displaceable.

The holding element 101 is pivotably mounted on a pivot bearing 104. From the holding arm 108 is an actuating arm 103, for example at right angles, from. The handling of the holding element 101 is facilitated by the fact that the actuating arm 103 is an abutment arm 43 opposite, so that an operator can take the actuating arm 103 and the abutment arm 43 with two fingers, for example, and move toward each other to the fixation of the adjusting body 51 with respect to the guide device 20th on the basis of the guide-fastening device 100 to solve, therefore, to actuate the holding member 101 in the release position. The actuating arm 103 and the abutment arm can thus be moved towards each other like a pliers (arrow P2). The holding element 101 is acted upon by a spring arrangement 107 in the direction of the holding position. In the direction of the release position, the holding element 101, in particular its holding arm 108, abuts against a stop 105.

The holding elements 81, 101 are preferably designed in the manner of holding pawls.

The toothing 102 is preferably at a free end or

Longitudinal portion of the support arm 108 is arranged. Thus, it can act with relatively high leverage on the counter-toothing 58, which allows a particularly firm grip. The toothings 58, 108 enable the adjusting body 51 to be fixed in different longitudinal positions relative to the guide depth adjusting element 70. The adjusting body 51 can therefore be immersed at different depths in the guide receptacle 72 and then fixed in each case with reference to the guide-fastening device 100 fixed relative to the guide device 20. Thus, therefore, many cutting depth positions can be defined. Of course, instead of the relatively fine corrugation or toothing 58, 108, a frictional engagement surface, a clamping surface or the like may also be provided, which likewise make a multiplicity of cutting depth positions adjustable.

It should be noted that, of course, an alternative to the drive-fastening means 80 drive-fastening means may comprise a clamping device.

Furthermore, in addition to the form-fitting receptacle 57a, at least one further form-fitting receptacle, a friction surface or the like may be provided as an abutment contour for the holding element 81 or an alternative holding element provided, for example, as a clamping element or frictionally engaging holding element.

The basis of the guide-fastening device 100 in different

Cutting depth positions fixable adjusting body 51 preferably forms a stop, for operation of the hand-cutting machine 10 as a submersible saw or Diving Ripper. The longitudinal end region 56, so to speak the head of the adjusting body 51, is positioned at the desired cutting depth, determined by means of the guide fastening device 100, so that it can represent a stop 56a for the drive assembly 11. For example, proposes the head 61 of the drive Tiefeneinstellelements 60 with its stop forming 61 a bottom on the adjusting body 51, the stop 56 a, to.

The operator can therefore press the drive assembly 11 against the force of the return spring device 65 towards the guide device 20 and thus allow the cutting tool 14 to dip into the workpiece W. Finally, in the diving depth or cutting depth set in this way, the drive fastening device 80 engages in the adjusting body 51, so that the tool holder 13 is fixed in the cutting depth position defined by the guide fastening device 100 with respect to the guide device 20.

Of course, it is also possible, as an alternative, for this latching function to be overridden. For example, this is possible because the spring arrangement 87 can be deactivated by a holder, for example. Furthermore, it is also possible that the holding member 81 is configured in the manner of a bolt, i. manually moved or pivoted between the release position and the holding position and thus remains in the release position without Federkraftbeaufschlagung.

The guide-fastening device 100 and the drive-fastening device 80 each allow a locking of the drive assembly 1 1 in a respective cutting depth position ST relative to the guide means 20. The Tiefeneinstelleinrichtung 50 thus forms a fixing device 77 and a latching device 78 for fixing or locking the drive assembly 1 first in a respective cutting depth position ST with respect to the guide device 20.

It is also possible that in an inventive

Hand-cutting machine no movable adjusting body in the type of Einstellkör- pers 51 is provided, but that so to speak the counter-locking contour is fixedly connected to the drive assembly or the guide means and cooperating with this counter-locking contour locking element, for example in the manner of holding elements 81 or 101, is provided.

The movable cover device 19 is designed in the manner of a pendulum hood. The covering device 19 pivots about the axis of rotation D, thus releasing the separating tool 14 for introducing a separating cut T in a pendulum movement or pivoting movement.

The covering device 19 is, for example, adjustable from its closed position S shown in FIG. 10, in which it at least substantially completely covers the separating tool 14, into an open position O according to FIG. 1, which is at least partially open. Opening movement can be achieved, for example, by a front, free end region 120 of the covering device 19 abutting the workpiece W laterally. In the opposite direction, i. in the direction of the closed position S, preferably acts a spring arrangement, for example, the closing spring 135 mentioned below. As a result, the covering 19 expediently always covers the cutting tool 14 when not in use the hand-ripper 10.

Expediently, a type of fin or fin, in any case a cutting wedge or guide element 121, is arranged on the end region 120. The guide element 121, for example, dives into the separating slot T on the workpiece as if and thus ensures, in particular during operation without the guide rail 90, for a straight separating cut.

But it is also possible that an operator actuates the cover 19 manually from the closed position S in the open position O. For this purpose, an actuating device 130 is provided which has an actuating element 131 which can be manually actuated by an operator. The actuating element 131 has an actuating arm 132, which is designed in the manner of an actuating lever. The actuating arm 132 is pivotally mounted on a pivot bearing 133 stored, wherein it pivots on actuation about the pivot bearing 133 and a driver lever 134 shown in solid lines, the closed position of the cover 19 associated position in a position shown in dashed lines, the open position O of the cover 19 assigned position adjusted can. The driver lever 134 actuates a cable pull mechanism not shown in detail, which opens the cover 19 so to speak, that is actuated in the open position. In the opposite direction acts a closing spring 135, for example, on the cam lever 134th
