Description

The present invention relates to an anti-tip device for attachment to a hand milling machine. In particular, the present invention relates to an anti-tip device for attachment to a hand milling machine, which has a base plate which has a support surface.

The present invention further relates to a hand milling machine system. In particular, the present invention relates to a hand milling machine system having an anti-tip device and a hand milling machine.

Examples from the prior art of such a hand milling machine are, for example, from EP 0 884 144 B1 known.

In general, electric hand tools, such as a hand milling machine, are subject to the trend of being able to be operated location-independently and, in particular, independently of a stationary power source. For this purpose, hand tools are usually equipped with batteries, especially rechargeable batteries. Since such batteries have a relatively high weight, connecting a battery to a hand tool generally results in a shift in the center of gravity of the hand tool. Due to this shift in focus, hand tools equipped with batteries can no longer be stored in a stable manner without fundamentally redesigning the hand tool itself; i.e., for example, they can no longer be put down and/or guided without tipping over. Furthermore, this can also result in poorer ergonomics of the hand tool and a worsened accuracy of the work result that can be achieved using the hand tool (e.g. due to slipping).

The present invention is therefore based on the object of solving the aforementioned problems, in particular of providing a tilt protection device for attachment to a hand milling machine, by means of which the hand milling machine can be stored in a particularly stable manner.

This object is achieved according to the invention by the features of claim 1. Advantageous developments of the invention are described in the dependent claims.

• - a fixing section for fixing the anti-tip device on the hand milling machine, and
• - a support section to supplement or expand the support surface of the base plate of the hand milling machine.

The support surface of the base plate can be used in particular to store the hand milling machine with or on it in an environment as intended, for example to park it. In particular, this can ensure that the hand milling machine can be put down or put down.

Additionally or alternatively, the support surface of the base plate can serve as a guide level during operation or use of the hand milling machine, via which the hand milling machine can, for example, be brought close to a workpiece in a defined manner.

The fixing section can have a substantially flat contact surface for essentially flush contact of the anti-tip device on the hand milling machine in the mounted state. Due to the flush contact, a direct force transmission between the anti-tip device and the hand-held milling machine can be ensured, which force can occur, for example, when the hand-held milling machine is put down and/or in the put-down state. For example, stresses and the resulting deformations or even breakage of the anti-tip device can be avoided.

It can be provided that in the mounted state only a part of the support section facing away from the base plate of the hand milling machine serves as a supplement or extension of the support surface of the base plate of the hand milling machine. For example, this can ensure permanent contact with a base when installed and/or it can be prevented that a supporting effect of the anti-tip device only takes place with a delay.

It can be provided that in the mounted state, a part of the support section facing the base plate of the hand milling machine, in particular a part of the support section adjacent or adjacent to the fixing section, forms a step with the base plate, the said part of the support section starting from the support surface of the Base plate is arranged in the direction of the rest of the base plate, i.e. in the direction of the rest of the hand milling machine, so that when the hand milling machine is placed down and / or moved longitudinally in the stored state, for example when the hand milling machine is in use, there is no interference from a shoulder between the base plate and the anti-tip device can occur.

It can be provided that the anti-tip device is made or can be made from a plastic, for example a fiber-reinforced plastic, and/or a metal, for example a light metal. In particular, the anti-tip device can be made or can be made from a polyamide, i.e. a PA, for example PA6, which, optionally, has a glass fiber content, for example between 20 and 40%, in particular 30%.

Identical or functionally equivalent elements are provided with the same reference numbers in all figures.

Referring to 1 until 11 , a tilt protection device 100 is used to attach to a hand milling machine 102.

The anti-tip device 100 and the hand milling machine 102 together form a hand Milling machine kit, a hand milling machine set or a hand milling machine system 104, which is in the 8th until 11 is shown schematically and is described in more detail below, in particular in connection with these figures.

In particular, the anti-tip device 100 is used for attachment to a hand milling machine 102, which has a base plate 106 which has a support surface 108 (cf. 8th ).

The support surface 108 of the base plate 106 serves in particular to store or park the hand milling machine 102 on this support surface 108 in an environment as intended.

Furthermore, the support surface 108 of the base plate 106 serves as a guide level during operation or use of the hand milling machine 102, via which the hand milling machine 102 can be brought, for example, in a defined manner to a workpiece (not shown in the figures).

The anti-tip device 100 is formed essentially along a longitudinal axis 110.

The anti-tip device 100 has a support section 112 to supplement or expand the support surface 108 of the base plate 106 of the hand milling machine 102.

In particular, the support section 112 is formed essentially along the longitudinal axis 110.

In the present exemplary embodiment, the support portion 112 is formed substantially rectangular, and the shape of the support portion 112 is not limited thereto.

The support section 112 has an upper side 114 and a lower side 116 as well as a front side 118 and a rear side 120. There are also lateral pages 122 between said pages 114, 116, 118, 120.

It should be clear that the terms front, back, bottom, top, side, etc. serve in particular to terminologically distinguish features from one another and/or to provide a relative orientation of features to one another.

The anti-tip device 100 also has a receiving section 124 for receiving a locking element 126 of the hand milling machine 102.

Such as in 1 until 5 can be seen, the receiving section 124 is formed on the support section 112. In particular, the receiving section 124 is formed on the upper side 114 of the support section 112.

The tipping protection device 100 further has a fixing section 128 for fixing the tipping protection device 100 on the hand milling machine 102.

The fixing section 128 has a substantially flat contact surface 130.

The contact surface 130 is aligned with respect to the anti-tip device 100 so that the longitudinal axis 110 of the anti-tip device 100 essentially forms a normal vector to it.

The contact surface 130 serves in particular to enable the anti-tip device 100 to rest essentially flush against the hand milling machine 102 when installed.

In the present exemplary embodiment, the fixing portion 128 is formed by the front side 118 of the support portion 112. That is, in the present exemplary embodiment, the abutment surface 130 extends over the front side 118 of the support portion 112. However, it can alternatively be provided that the fixing section 128 is formed independently or separately from the front side 118 of the support section 112.

The receiving section 124 extends from the upper side 118 of the support section 112.

The receiving section 124 has a receiving recess 132 for receiving the locking element 126.

The receiving recess 132 extends essentially parallel to the longitudinal axis 110 of the anti-tip device 100 and over the receiving section 124.

The receiving recess 132 is essentially U-shaped, in particular it has a substantially U-shaped profile.

As in 3 and/or 4 can be seen, the receiving section 124 has a substantially M-shaped profile.

In the essentially M-shaped profile, the U-shaped receiving recess 132 is arranged centrally and the respective outer legs have a concavely curved course.

Furthermore, the receiving section 124 has a first leg 134 and a second leg 136.

The first and second legs 134, 136 are arranged at a distance from one another and serve to receive the locking element 126 therebetween.

The first and second legs 134, 136 are arranged in the receiving recess 132 and extend therefrom.

Like in particular 2 can be seen, the first and second legs 134, 136 extend essentially parallel to the contact surface 130 of the fixing section 128.

The first and second legs 134, 136 are connected to one another at their base and essentially form a U-shaped structure.

The U-shaped structure is arranged in a manner corresponding to the receiving recess 132, so that the locking element 126 can be received therein by means of the open side, for example the side open towards the top, of the U-shaped structure.

When installed (cf. 9 and 10 ), the locking element 126 is arranged between the first and second legs 134, 136 and in the receiving recess 132.

Furthermore, the first and second legs 134, 136 can be locked in a clamping manner when attached to the hand milling machine 102 or locked by means of the removable or recorded locking element 126 (cf. 9 and 10 ).

Referring to 6 and 7 , the support section 112 has a substantially flat support surface 138 to supplement or expand the support surface 108 of the base plate 106 of the hand milling machine 102.

The support surface 138 of the support section 112 and the contact surface 130 of the fixing section 128 are arranged at an angle of approximately 97 degrees to one another.

In the present exemplary embodiment, that is, with respect to the longitudinal axis 110 of the anti-tip device 100, the support surface 138 is disposed at an angle of approximately 7 degrees.

In the present exemplary embodiment, the support surface 138 is designed as an at least partially open support surface, which is formed and/or defined by a rib arrangement 140 of the support section 112.

In other words, the support section 112 has a rib arrangement 140 which forms and/or defines the at least partially open support surface 138.

The rib arrangement 140 has a circumferential edge rib 142 and two intermediate ribs 144, for example intermediate webs, arranged within the edge rib 142.

The support surface 138 can be viewed or defined as the surface which is encompassed by the circumferential edge rib 142.

Like in particular 8th and 9 As can be seen, when installed, the longitudinal axis 110 of the anti-tip device 100 is aligned essentially parallel to a longitudinal axis 146 of the hand milling machine 102.

In the mounted state, only a part of the support section 112 facing away from the base plate 106 of the hand milling machine 102 serves as a supplement or extension of the support surface 108 of the base plate 106 of the hand milling machine 102.

For example, this part of the support section 112 facing away from the base plate 106 of the hand milling machine 102 is an edge section 148 between the lower and rear sides 116, 120 of the support section 112, in particular the section of the edge rib 142 of the rib arrangement 140 facing the rear side 120.

This is achieved in particular by, in the assembled state, the support section 112 forming a step or a step with the base plate 106 along the direction of the contact surface 130, in particular upwards along the direction of the contact surface 130, and configuring the support surface 138 at the previously described angle is.

Referring to 1 until 11 The anti-tip device 100 is made, for example, from a fiber-reinforced plastic, in particular from a polyamide PA with a glass fiber content GF of 30%, preferably from PA6 with GF 30%, or can be produced by injection molding.

The following will be discussed in particular 8th until 11 Referenced, which schematically represent the already mentioned hand milling machine system 104.

The hand milling machine system 104 includes an anti-tip device 100 configured as described herein and a Hand milling machine 100 configured as described herein.

As in 8th can be seen, the hand milling machine 102 is formed and in particular constructed essentially along the longitudinal axis 146 already mentioned above.

The hand milling machine 102 also has a battery receiving area 150 for receiving a battery 152.

The battery receiving area 150 is arranged in a rear section of the hand milling machine 102 with respect to the longitudinal axis 146.

In the exemplary embodiment shown here, the battery 152 is coupled to the battery receiving area 150.

The base plate 106 is arranged in a front, in particular a front lower, section of the hand milling machine 102 with respect to the longitudinal axis 146.

With the battery 152 in place, the center of gravity SP of the hand milling machine 102 is arranged between the base plate 106 and the battery receiving area 150 with respect to the longitudinal axis 146 (see cross marking in 8th ). This causes a moment to act on the hand milling machine 102, so that the hand milling machine 102 can be tilted or would tilt solely around a rear edge of the base plate 106 (with respect to the longitudinal axis 146).

A battery rotating device 154 is assigned to the battery receiving area 150.

By means of the battery rotation device 154, the battery 152 can be rotated about an axis of rotation 156 in the recorded state.

In other words, the hand milling machine 102 has a battery rotating device 154, which is assigned to the battery receiving area 150 and by means of which the battery 152 can be rotated about a/the axis of rotation 156 in the recorded state.

By means of the battery rotation device 154, the battery 152 is about the rotation axis 156 between a first position, which is in 8th is shown, and rotatable to a second position.

The first position corresponds to a 0 degree rotation (ie, the battery 152 is according to the orientation of 8th downward) and the second position in the present exemplary embodiment corresponds to a 180 degree rotation (ie, the battery 152 would be according to the orientation of 8th directed upwards).

Like in the 8th until 11 is shown, the anti-tip device 100 is locked on a side of the base plate 106 facing the direction of the battery receiving area 150 by means of the locking element 126.

As a result, the support surface 108 of the base plate 106 of the hand milling machine 102 is expanded beyond the center of gravity SP with respect to the longitudinal axis 146 of the hand milling machine 102. This constructively counteracts the aforementioned moment, so that the hand milling machine 102 alone no longer revolves around the rear edge of the base plate 106 (with respect to the longitudinal axis 146) is or would tilt. The anti-tip device 100 therefore serves to change a tipping point of the hand-held milling machine 102 in order to re-arrange the center of gravity SP of the hand-held milling machine 102 at a sufficient distance within a tipping limit in relation to the longitudinal axis 146 of the hand-held milling machine 102.

Referring to 9 and 10 , the locking element 126 is designed as a screw, which can be received in the receiving section 124 of the anti-tip device 100 or according to 9 and 10 is recorded.

The screw extends substantially along a longitudinal axis 158 and has a screw head 160 and a screw shaft 162 connected to the screw head 160 and which is at least partially threaded.

When grown, in the 8th until 11 is shown, at least a part of the receiving section 124, in particular the first and second legs 134, 136 of the receiving section 124, is locked in a clamping manner between the base plate 108 and the screw head 160, whereby the anti-tip device 100 is locked in a clamping manner on the hand milling machine 102.

This clamp connection can be released by screwing the locking element 126 in one screwing direction and can be produced in the opposite screwing direction.

Due to the upwardly open structure of the first and second legs 134, 136, the screw does not have to be completely unscrewed in order to enable coupling with the anti-tip device 100, but can be pushed from below between the base plate 108 and the screw head 160, so that the screw shaft 162 is arranged between the first and second legs 134, 136. A Subsequent tightening of the screw can produce the said clamp connection or clamp lock.

Furthermore, the anti-tip device 100 and the hand milling machine 102 each have mutually corresponding positive locking elements, which are brought into engagement with one another in the installed state, whereby rotation of the anti-tip device 100 and the hand milling machine 102 relative to one another with respect to the longitudinal axis 158 of the screw can be prevented.

In the present exemplary embodiment, the positive locking element of the hand milling machine 102 is designed as a nose 164, which is formed on the base plate 106 adjacent to the locking element 126.

Furthermore, the corresponding positive locking element of the anti-tip device 100 is designed as a supporting edge 166 on the receiving section 124.

Referring to 11 The anti-tip device 100 has a width dimension ratio of 1/3 with respect to the extension of the hand milling machine 102, in particular the base plate 106, in a width direction. Since the anti-tip device 100 is arranged centrally on the base plate 106, when installed, a third of the width, ie, 1/3 B, of the base plate 106 is free on each side of the anti-tip device 100 (cf. 11 ). This can, for example, prevent the hand milling machine 102 from tipping over corner points of the base plate 106 and/or the anti-tip device 100 during a depositing process.

Again referring to 8th the hand milling machine 102 further comprises a housing 168 which has a motor (not shown in the figures).

The hand milling machine 102 also has a milling knife coupled to the motor via a gearbox (not shown in the figures) and a carriage 170 which can be displaced along the longitudinal axis 146 relative to the housing 168 and which has an opening for the milling knife to exit.

The base plate 106, in particular the support surface 108 of the base plate 106, forms a lowermost part of the carriage 170 in order to ensure that the hand milling machine 102 can be stored.

The housing 168 is in relation to the carriage 170 between an in 8th generated first end position, in particular a rest position, and a second end position, in particular a milling position, connected in a continuously displaceable manner.

For example, in the first end position, the milling knife is completely recessed inside the carriage 170 and the opening for the exit of the milling knife is free.

For example, in the second end position, the milling knife protrudes at least partially from the interior of the carriage 170 through the opening to the exit of the milling knife in order to enable a milling process.

In particular, the housing 168 is slidably connected to the carriage 170 via guide surfaces.

The hand milling machine 102 also has a return device (not shown in the figures), for example in the form of a spring, which is set up between the housing 168 and the carriage 170, for example connected to them, and by means of which the housing 168 is opposite the carriage 170 can be returned to the first end position from the second end position and/or an intermediate position arranged between the first and the second end position.

The hand milling machine 168 also has a stop plate 172, which is pivotally mounted on or in the carriage and defines a substantially flat front stop 174 of the hand milling machine 102.

In particular, the stop plate 172 is between a substantially vertical position (in 8th shown) and reversibly pivotable in a position inclined with respect to the support surface 108.

The stop plate 172 can be locked in any position between the said positions by means of a clamping device 176 assigned to it, for example in the form of a screw.

The hand milling machine further has: a handle 178 provided on the housing 168 for handling or operating the hand milling machine 102, and a switch 180 provided on the housing 168 for switching the motor on and off.

In 12 and 13 a particle collection device 182 is shown in the form of a dust bag device for attachment to the hand milling machine 102.

Like in the 8th and 9 can be seen is the particle collection device 182 on the hand milling machine machine 102 attached. For reasons of clarity, in the 8th and 9 only a portion 184 of the particle collection device 182 is shown coupled to the hand milling machine 102.

The particle collecting device 182 is or is attached to the hand milling machine 102 in order to be able to collect particles, in particular dust, chips and / or the like, which are or are released from or from a processing workpiece during operation or use of the hand milling machine 102 by means of the milling knife.

The hand milling machine 102, in particular the carriage 170 of the hand milling machine 102, has a coupling point for connecting the particle collecting device 182 to the hand milling machine 102.

In the present exemplary embodiment, the coupling point is arranged and/or set up adjacent to the locking element 126 (cf. 8th and 9 ).

Consequently, the particle collection device 182 can be installed adjacent to the anti-tip device 100 on the hand milling machine 102.

The coupling point is connected to a working area of the milling cutter, for example by means of a dust guide passage, for guiding particles, in particular dust, chips and/or the like, from the working area to the attached particle collecting device 182.

The particle collection device 182 has an adapter 184, in particular a suction adapter, for coupling the particle collection device 182 to the hand milling machine 102.

Furthermore, the particle collection device 182 has a bracket 186, in particular a wire bracket, which can be reversibly attached or attached to the adapter 184.

Furthermore, the particle collection device 182 has a collection container 188, in particular a bag, for example a dust bag, which can be reversibly attached or attached to a first end region 190 of the adapter 184 in order to be able to receive and collect particles through the adapter 184.

Furthermore, the particle collection device 182 has a closure cover 192 for reversibly closing a second end region 194 of the adapter 184 in an unassembled state of the particle collection device 182 with the hand milling machine 102.

The adapter 184 is constructed substantially along a longitudinal axis and includes a dust control passage along the longitudinal axis.

The first and second end regions 190, 194 are arranged at opposite ends of the adapter 184 and each have an opening, which respectively forms a beginning and an end of the dust guide passage.

The collecting container 188 can be manufactured or made from a textile material, for example a fabric.

The bracket 186 is inserted into the collecting container 188 to shape it.

In 14 is a schematic perspective view of an anti-tip device 100 according to a further exemplary embodiment of the invention.

In the 14 The anti-tip device 100 shown essentially corresponds to that in the 1 until 11 shown anti-tip device 100, so that only the differences are described below.

As in 14 As can be seen, the first and second legs 134, 136 are connected to one another both at their base and at their part opposite the base and essentially form an O-shaped structure.

In other words, the first and second legs 134, 136 form an annular element, in particular a ring element 196.

The O-shaped structure is arranged corresponding to the receiving recess 132 in this, so that the locking element 126 can be inserted and passed through it and thus received by means of the open side, for example the side open towards the rear, of the O-shaped structure.

In other words, the ring element 196 is arranged in the receiving recess 132 correspondingly, so that the locking element 126 can be inserted and passed through it by means of the open side, for example the side open towards the rear, of the ring element 196 and can therefore be received.

In the mounted state, the locking element 126 is arranged between the first and second legs 134, 136 and is surrounded by them with respect to a circumference.

In other words, when installed, the locking element 126 is in the ring ment 196 and is enclosed by it in terms of a circumference.
