DETAILED DESCRIPTION
[0064] FIG. 1 shows a power tool 10 with a first housing 20 and a second housing 22, the two housings 20, 22 being arranged next to each another. In the context of the invention, this means that the first housing 20 and the second housing 22 are arranged substantially at the same height in relation to an upward/downward direction of the power tool 10. The upward/downward direction and a forward/rearward direction are shown in the figures by means of a directional cross. The upward/downward direction preferably runs between the upward O and downward U spatial directions, while the forward/rearward direction runs between the forward V and rearward H spatial directions. In other words, the upward/downward direction preferably extends between a top side 10O and an underside 10U of the power tool 10, while the forward/rearward direction extends between the tool fitting 38 of the exchangeable energy supply device 18. The tool fitting 38 preferably forms a front region of the power tool 10, while the exchangeable energy supply device 18 forms the rear region of the power tool 10. The side surfaces S1, S2 (see, e.g., FIG. 4) of the power tool 10 form the lateral boundaries of the housings 20, 22 of the power tool 10. FIGS. 1 and 3 in particular depict the left side S1 of the power tool 10, to which, for example, a lateral handle 36 can be fastened.
[0065] The power tool 10 shown in FIG. 1 has a drill stand interface 32 on the underside 10U of the power tool 10. In the power tool 10 depicted in FIG. 1, the at least one exchangeable energy supply device 18 is arranged in a continuation of the motor axis A2.
[0066] The power tool 10 illustrated in FIG. 1 is preferably designed as a purely stand-guided power tool 10, and therefore the power tool 10 preferably does not have any handles 34, 36. In other configurations of the invention, however, a purely stand-guided power tool 10 can also have handles, such handles being able to be provided, for example, for positioning the power tool 10 on a drill stand 30. The drill stand interface 32 serves to fasten the power tool 10 to a drill stand 30 (see FIG. 5). The power tool 10 depicted in FIG. 1 is designed as a core drill and has a drill bit as the tool 12 (see. e.g., FIG. 5). The tool 12 can be fastened to the power tool 10 with a tool fitting 38. The power tool 10 has a motor 16, the position of which within the power tool 10 can be described by a motor axis A2. The motor 16 has a motor shaft 24 and can generate a rotary movement, the rotary movement being able to be transmitted to the tool 12 by means of a shaft device 14. The position of the shaft device 14 within the power tool 10 can be described by a shaft axis A1. The shaft axis A1 preferably runs centrally through the shaft device 14 and the tool 12 of the power tool 10, with the shaft axis A1 preferably forming the drilling axis of the power tool 10. The motor axis A2 preferably runs centrally through the motor 16 of the power tool 10. The motor 16 is preferably in the form of an electric motor and preferably comprises a stator and a rotor.
[0067] A detailed view of the shaft axis A1 and the motor axis A2 of the power tool 10 is depicted in FIG. 2.
[0068] The power tool 10 can be connected to at least one exchangeable energy supply device 18 for the purpose of supplying energy. For example, the power tool 10 can have a battery 18 or two batteries 18 as a rechargeable energy supply device 18. Rechargeable energy supply devices are preferably also referred to as rechargeable batteries in the context of the invention. The batteries 18 or rechargeable batteries 18 can be charged with a charger (not illustrated) when they have been depleted by the operation of the power tool 10. As an alternative to the batteries or rechargeable batteries, the exchangeable energy supply device 18 can be formed by a mains adapter. In this case, the power tool 10 can be supplied with electrical energy by means of the mains adapter 18. The mains adapter 18 can be connected to a power grid, such as a public power grid or a construction site power grid, via a power cord (not illustrated). The exchangeable energy supply device 18 can be connected to the power tool 10 via a receiving device (not illustrated) for the exchangeable energy supply device 18. In the context of the invention, said receiving device can preferably also be referred to as an energy interface. It is preferred in the context of the invention that the power tool 10 has a universal energy interface with which both batteries 18 and mains adapter 18 can be connected to the power tool 10. The energy supply device 18 can be inserted into a cavity of the power tool 10. The insertion preferably takes place in an insertion direction E.
[0069] The power tool 10 has a first housing 20 and a second housing 22. The first housing 20 at least partially encloses the motor 16 of the power tool 10, while the second housing 22 is configured to at least partially enclose the exchangeable energy supply device 18 of the power tool 10, in particular when the exchangeable energy supply device 18 is arranged in the power tool 10. According to the invention, the shaft axis A1 is substantially parallel to or collinear with the motor axis A2. In the power tool 10 illustrated in FIG. 1, the motor 16 and the exchangeable energy supply device 18 are arranged substantially at the same height with respect to an upward/downward direction of the power tool 10. The motor axis A2 runs below the shaft axis A1, with the motor axis A2 and the shaft axis A1 running substantially parallel to each another. The shaft device 14 is preferably configured to transmit a rotational movement of the motor 16 of the power tool 10 to the tool 12. The first housing 20 and the second housing 22 can also form housing regions of a superior housing, the first housing region 20, which preferably corresponds to the first housing 20, being configured to protect the motor 16 of the power tool 10, while the second housing region 22, which preferably corresponds to the second housing 22, is configured to protect the energy supply unit 18 of the power tool 10. FIGS. 1 to 10 in particular illustrate a two-part housing consisting of a first housing 20 and a second housing 22. However, the invention is not limited to a two-part housing 20,22; rather, the power tool 10 is also intended to be able to comprise a single-part housing. However, such a single-part housing can preferably comprise different functional housing regions, such as a motor housing region 20, for protecting the motor and/or a battery housing region 22 for protecting the energy supply device.
[0070] The drill stand 30 partially illustrated in FIG. 1 or in FIG. 5 has a handwheel with which a drilling feed can be transmitted to the power tool 10. The handwheel is preferably a feed device 40, with it being possible for the generation of the drilling feed to be preferably taken over by an automatic feed device. In the system 100 which is illustrated in FIG. 5 and consists of a power tool 10 and a drill stand 30, a drilling feed is generated in a downward U spatial direction and transmitted to the power tool 10. The tool fitting 38 of the power tool 10 (front region of the power tool 10) therefore points in the downward U spatial direction, while the exchangeable energy supply device 18 (rear region of the power tool 10) points in an upward O spatial direction. The drill stand interface 32 is present on the underside 10U of the power tool 10 in the power tool 10 illustrated in FIGS. 1 and 5. In the context of the invention, it is preferred that the feed device 40 can be used to generate a drilling feed in a downward U spatial direction. Said drilling feed is preferably directed in a forward direction V of the shaft axis A1.
[0071] FIG. 3 shows a side view of a power tool 10 with two housings 20, 22 offset with respect to each other, and with a rear handle 34. The wording that the first housing 20 and the second housing 22 are arranged offset with respect to each another preferably means, in the context of the invention, that the second housing 22 of the power tool 10 is offset in a downward U spatial direction in an upward/downward direction in comparison to the first housing 20. In the case of the power tool 10 shown in FIG. 3, the exchangeable energy supply device 18 and the second housing 22 are present below the first handle 34, which is preferably referred to as a rear handle 34. The motor 16 or the first housing 20 of the power tool 10 is arranged next to and in particular in front of the first handle 34. In other words, the motor 16 and the first housing 20 are arranged obliquely offset in the upward O and forward V spatial directions in relation to the exchangeable energy supply device 18 and the second housing 22. In this exemplary embodiment of the invention, the drill stand interface 32 is preferably arranged on a top side 10O or on the side walls S1, S2 of the power tool 10.
[0072] In the context of the invention, this preferably means that the drill stand interface 32 for fastening the power tool 10 to a drill stand 30 can be arranged, for example, laterally on the power tool 10. However, the drill stand interface 32 may also be arranged on a top side 10O of the power tool 10. The power tool 10 depicted in FIG. 3 can be used in a stand-guided and/or hand-held manner. In the context of the invention, this preferably means that the power tool 10 depicted in FIG. 3 is a universally usable power tool 10 which can be held in the hand of a user during operation or which can be fastened to a drill stand 30 during operation. The housings 20, 22 of the power tool 10 are illustrated in the figures in different contrasts or different colors or hatching.
[0073] The energy supply device 18 can be inserted into a cavity of the power tool 10. In this case, the insertion preferably takes place in an insertion direction E. In the exemplary embodiment of the invention shown in FIG. 3, the energy supply device 18 is introduced into the power tool 10 from the rear. The insertion direction E thus runs from a rear side of the power tool 10 in a forward V spatial direction. In the exemplary embodiment of the invention shown in FIG. 3, the insertion direction E runs substantially parallel to the shaft axis A1 and/or the motor axis A2.
[0074] FIG. 4 shows a rear view of a power tool 10 with two housings 20, 22 arranged offset with respect to each other, and with a side handle 36. The side handle 36 can preferably also be referred to as a second or front handle in the context of the invention. The exchangeable energy supply device 18 and the second housing 22 are illustrated in the lower, rear region of the power tool 10, while the rear handle 34 is illustrated above the exchangeable energy supply device 18.
[0075] FIG. 5 shows a side view of a system 100 consisting of a power tool 10 and a drill stand 30.
[0076] FIG. 6 shows an oblique rear view of a power tool 10 with two housings 20, 22 arranged offset with respect to each other, a side handle 36 (almost concealed) and a sensor 28 on the opposite side of the power tool 10. The power tool 10 depicted in FIG. 6 has a protective device 44 for the exchangeable energy supply device 18, and a display device 42. Different operating parameters, the connection state of the power tool 10 to a drill stand 30, motor characteristics or performance parameters can be displayed and/or set on the display device 42. The protective device 44 can surround the exchangeable energy supply device 18 and can be at least partially elastic in order to absorb impact forces in the event of dropping and to protect the exchangeable energy supply device 18 from damage. The at least one sensor 28 is configured to detect a connection state of the power tool 10 to a drill stand 30. Of course, the sensor 28 can be arranged at many different locations on the power tool 10. The sensor 28 can be integrated in the power tool 10 or, for example, can be subsequently fastened as a retrofit component to the power tool 10. It is preferred in the context of the invention that the sensor 28 is arranged in spatial proximity to the drill stand interface 32. The sensor 28 can preferably be integrated in the power tool 10. In alternative configurations of the invention, however, the sensor 28 can also be provided as a retrofit solution for the power tool 10.
[0077] FIG. 6 shows an oblique rear view of a power tool 10 with two housings 20, 22 arranged offset with respect to each other, a side handle 36 and a sensor 28. The sensor 28 can preferably be used to detect directly whether a power tool 10 is mounted on a drill stand 30. In other words, the sensor 28 can detect different connection states of the power tool 10, in particular whether a power tool 10 is arranged or is not arranged on the drill stand 30. The sensor 28 can be designed as a mechanical switch, proximity sensor and/or optical sensor. The sensor 28 can be configured to preferably automatically emit or send an installation signal when the power tool 10 is installed. In the event of removal of the power tool 10, the sensor 28 can be designed to emit or send a removal signal. For example, the signals can be output via optical output means such as displays or LEDs. However, in the context of the invention, it may also be preferred for the signals to be processed by information technology within the power tool 10 and/or used to control, display and/or adjust operating parameters. Advantageously, operating parameters or motor characteristics of the power tool 10 can be set or changed depending on a connection state of the power tool 10 to a drill stand 30. Said setting or adjustment or change preferably takes place automatically. For example, the power tool 10 can be controlled in a drill stand operating mode when the power tool 10 is arranged on a drill stand 30 and this is detected by the sensor 28. In addition, the power tool 10 can be controlled in a manual operating mode if the power tool 10 is held during its operation by a user's hand and this is detected by the sensor 28. The sensor 28 is preferably configured to detect an installation state on the drill stand 30. This means that the sensor 28 can detect whether the power tool 10 is mounted on a drill stand 30 (drill stand operating mode) or not. If the power tool 10 is not mounted on a drill stand 30, the power tool 10 can be operated in the manual operating mode, for example.
[0078] The exchangeable energy supply device 18, which is arranged in the second housing 22, can be seen clearly in FIG. 6. The exchangeable energy supply device 18 can be surrounded by a protective device 44 for the exchangeable energy supply device 18 to protect it against being dropped or against mechanical damage. In the exemplary embodiment of the invention 18 shown in FIG. 6, the energy supply device 18 can be inserted into the power tool 10 from behind; the insertion direction preferably runs from a rear side of the power tool 10 in a forward V spatial direction. Also in the exemplary embodiment of the invention shown in FIG. 6, the insertion direction E runs substantially parallel to the shaft axis A1 and/or the motor axis A2.
[0079] In addition, a display device 42 can be seen in the oblique rear view of the power tool 10 depicted in FIG. 6, which display device can have input and output means and is preferably arranged such that it can be easily seen by a user. The first, rear handle 34 is illustrated in the rear, upper region of the power tool 10, while the exchangeable energy supply device 18 is depicted in the rear, lower region of the power tool 10. In the power tool 10 illustrated in FIG. 6, the housings 20, 22 of the power tool 10 are offset with respect to each other both in an upward/downward direction and in a forward/rearward direction. In the context of the invention, this preferably means that the exchangeable energy supply device 18 and the second housing 22 are arranged in a rear, lower region of the power tool 10, while the motor 16 and the first housing 20 are arranged in a central, upper region of the power tool 10. The tool fitting 38 for the tool 12 of the power tool 10 is present in the front region of the power tool 10. The tool 12 can be driven by a shaft device 14, with the drilling axis A1 preferably running centrally within the shaft device 14 or centrally within the tool 12.
[0080] In the power tool 10 illustrated in FIG. 6, the sensor 28 is arranged on the right side S2 of the power tool 10, while the second, lateral handle 36 is arranged on the left side S1 of the power tool 10. It is preferred in the context of the invention for the sensor 28 and the drill stand interface 32 to be stationary and arranged in spatial proximity to each another on the power tool 10. The side handle 36 can be rotatable, for example. For example, the side handle 36 of the power tool 10 can be rotated by up to 360. As a result, the operability of the power tool 10 can be significantly improved, for example for left-handers.
[0081] FIG. 7 shows a side view of a preferred embodiment of the power tool 10 with a second handle (side handle) 36 and a third handle (T handle) 46. FIG. 8 shows an oblique rear view of such a power tool 10. As can be seen from the different positions of the second handle 36 of the power tool 10, the second handle 36, which in the context of the invention is preferably also referred to as a side grip or side handle 36, can be rotatable, so that the second handle 36 can be rotated about a neck of the power tool 10. Complete rotatability of the second handle 36 by 360, for example, is preferred. However, lesser rotatability may also be provided. Preferably, the shaft axis A1 can be considered to be the axis of rotation of the second handle 36. In other words, the second handle 36 can rotate about the shaft axis A1. In FIG. 7, the second handle 36 extends along an upward/downward direction of the power tool 10, so that the second handle 36 or an imaginary, virtual axis through the second handle 36, is substantially perpendicular to the shaft axis A1 or to the motor axis A2 running substantially parallel to or collinearly therewith. In the power tool 10 illustrated in FIG. 8, the second handle 36 is rotated by 90 in comparision to the position of the second handle 36 shown in FIG. 7, and therefore the second handle is oriented substantially horizontally in FIG. 8 and protrudes to the side of the power tool 10.
[0082] The third handle 46 is also arranged on the underside U of the power tool 10 in the power tool 10 illustrated in FIG. 7. A third axis A3 can be placed virtually through the third handle 46, said third axis enclosing an angle alpha with the shaft axis A1 and/or the motor axis A2. Angle alpha is shown in FIG. 7. The third axis A3 and the shaft axis A1 and/or the motor axis A2 enclose two opposite angles which add up to an angle sum of 180. In the context of the invention, the angle alpha is preferably the smaller of the two opposite angles. The angle alpha can be, for example, about 80, with it being preferred in the context of the invention that the angle alpha lies in a range from 60 to 100 or in a range from 70 to 90. These angles advantageously lead to particularly ergonomic power tool postures, so that the power tool 10 can be used particularly gently and/or for long periods of time. In the power tool illustrated in FIG. 7, the second handle 36 and the third handle 46 lie in a plane which extends below the power tool 10. In the power tool 10 illustrated in FIG. 8, the second handle 36 and the third handle 46 are specifically not in the same plane; rather, the second handle 36 is rotated by 90 such that the second handle 36 is virtually perpendicular to said plane below the power tool 10. The display device 42, which can be provided on the rear side H of the power tool 10, is clearly visible in FIG. 8. The display device 42 is preferably embedded in the second housing 22 of the power tool 10.
[0083] The third handle 46 can be arranged below the first housing 20. Alternatively or additionally, the third handle 46 can be arranged below the second housing 22. In the context of the invention, it can be very particularly preferred that the third handle 46 is arranged below a transition region between the first housing 20 and the second housing 22. As a result, an ergonomically particularly well-balanced power tool 10 can be provided.
[0084] In the exemplary embodiment of the invention shown in FIG. 8, the insertion direction E of the energy supply device 18 runs substantially perpendicular to the shaft axis A1 and/or the motor axis A2. In the context of the invention, this preferably means that the energy supply device 18 can be introduced laterally into the power tool 10. The energy supply device 18 can preferably be introduced into the power tool 10 from right to left or from left to right. The energy supply device 18 can thus be installed in the power tool 10 transversely with respect to the shaft axis A1 and/or the motor axis A2. A battery axis can be defined, which preferably coincides with the insertion direction E and which, in the exemplary embodiment of the invention shown in FIG. 8, likewise runs perpendicularly or transversely with respect to the shaft axis A1 and/or the motor axis A2 of the power tool 10.
[0085] FIG. 9 shows a side view of a preferred configuration of a power tool 10 with an inclined display device 42. The display device 42 can be arranged on the rear side H of the power tool 10 and can be embedded in the second housing 22 of the power tool 10. The wording that the display device 42 can be arranged at an inclination preferably means in the context of the invention that a plane 48 in which the display device 42 lies encloses an angle beta with the shaft axis A1 and/or the motor axis A2, said angle beta being able to be in a range between 20 and 70. The angle beta is shown in FIG. 9. The inclined arrangement of the display device 42 enables the display device 42 to be viewed particularly easily by a user and the information and data displayed can be detected in a particularly uncomplicated manner. The display device 42 is arranged in particular in such a way that it lies in the field of view of the user of the power tool 10.
[0086] FIG. 10 shows a rear view of a preferred embodiment of a power tool 10 with battery protection elements 50. The battery protection elements 50 can form a protective device 44 for the energy supply device 18 of the power tool 10. The battery protection elements 50 can preferably be pillar-like, tapering elements that protrude from the housing 20, 22 of the power tool 10 in the manner of stalagmites or spikes. The battery protection elements 50 can have a height h that is greater than a protrusion d of the energy supply device 18 beyond the power tool 10. As a result, the corners of the energy supply device 18 of the power tool 10 can be protected particularly well against the power tool being dropped or falling over. The protrusion d is shown in FIG. 10. The protrusion d is preferably smaller than the height h of the battery protection elements: d<h in order to ensure optimal protection of the energy supply device 18 of the power tool 10.
[0087] Also in the exemplary embodiment of the invention shown in FIG. 10, the insertion direction E of the energy supply device 18 runs substantially perpendicularly or transversely with respect to the shaft axis A1 and/or the motor axis A2 of the power tool 10. As a result, the energy supply device 18 can advantageously be introduced laterally into the power tool 10 such that a particularly short and compact power tool 10 can be provided. The energy supply device 18 can preferably be introduced into the power tool 10 from right to left or from left to right, which is intended to be indicated by the arrow with the two arrowheads. The energy supply device 18 can be installed in the power tool 10 transversely with respect to the shaft axis A1 and/or the motor axis A2 such that a battery axis also runs perpendicularly or transversely with respect to the shaft axis A1 and/or the motor axis A2 of the power tool 10.
[0088] FIG. 11 shows one possible configuration of the power tool 10 with an accessory device 60. The accessory device 60 has a soft supporting surface 64 that faces the user of the power tool 10 when the user is working with the power tool 10. The supporting surface 64 can be arranged on a body 62, the body 62 also comprising connecting means 66 or being connected to said connecting means 66.
