Description

The invention relates to a system comprising at least a first adapter assembly which is connectable to a power tool on the one hand and at least one second adapter assembly which is connectable to an electrical appliance on the other hand. The invention also relates to an adapter assembly for use in such a system, an adapter plug and each a method of monitoring and control for an adapter assembly and a system.

In principle, such a system can be used for any conceivable electrical appliance, and thus in particular for use with a power tool on the one hand and for supplying at least one electrical appliance on the other hand, in particular a light source and / or a suction device and / or a heater and / or a ventilation device and / or a filter device , suitable. As a particularly suitable system, a system comprising a power tool and a suction device can be considered.

As a power tool machine in the present case are understood both devices that are supplied in a wired manner from the mains or wirelessly from one or more battery packs or battery packs with energy.

On a construction site, it is common to use a variety of power tools and electrical appliances more or less simultaneously. Sometimes a synchronous operation of a power tool and another electrical device is useful or even necessary. For example, it may be advisable in the operation of dust or particle-generating power tools such as drills, electric saws or grinders to provide a suction device that starts at the same time when commissioning the power tool and ensures that occurring dust or particles are avoided or sucked as possible. Furthermore It may be provided to switch on a light source or ventilation device at the beginning of an operation.

It has been found in practice to be uncomfortable to manually turn on or off an electrical appliance to be operated simultaneously with a power tool in addition to the power tool. The additional necessary operations can not least increase the risk of injury on construction sites or reduce the prevailing care in dealing with the machinery there.

In the meantime, various solution concepts have been developed to increase comfort and safety on construction sites. It is known, for example, to provide a suction hose coupled to a circular saw, which leads directly to a suction device, in addition to a 230 volt power cable, whereby the electric suction device receives its electrical energy directly from the circular saw when needed. About the electric circular saw thus the suction device can be switched on automatically when needed. However, this concept shows two significant disadvantages. On the one hand, the principle can only be used with power tool machines that themselves are supplied with power directly from the power grid. On the other hand, the already rigid and difficult to move suction hose is now even harder to handle by the interwoven power cord than before, which unnecessarily complicates an accurate or filigree work, especially in hand-held power tools.

An alternative is for example in the DE 10 2012 003 073 A1 disclosed. It is provided that a suction device for separating particles from a suction flow during operation of a drive motor for driving a tool having hand tool is used. In the suction device it is provided that it has a suction device communication device for communication with an external communication device to be operated at a distance from the suction device housing in connection with the handheld power tool. hereby a bidirectional and non-wired mutual control of the devices is possible. A disadvantage of this concept is the fact that the hand tool can only communicate with the extra suction device provided for this purpose. A flexible control of any electronic devices or suction devices of other manufacturers is thus excluded. The use of the system on the construction site is thus only possible to a very limited extent.

In view of the known state of the art, the object of the present invention is to provide a system of an adapter assembly which enables convenient and automatic operation of a wide range of electrical appliances starting from a power tool.

Accordingly, a system with the features of claim 1 is proposed.

In the solution according to the invention, it is provided that the at least one first adapter arrangement comprises a radio module for transmitting data to the at least one second adapter arrangement, wherein the at least one second adapter arrangement comprises a radio module for receiving data from the at least one first adapter arrangement and also for providing or disconnecting an electrical connection of the electrical device connected to the second adapter arrangement with an electrical energy source and for this purpose has an input-side interface and an output-side interface and a controllable switching device, wherein the controllable switching device is electrically connected to the radio module for receiving data and set up is to provide or disconnect optionally an electrical connection of the input-side interface with the output-side interface.

Particularly advantageous in the inventive solution is that by providing each of an adapter assembly to the power tool and an adapter assembly to the electrical appliance highest flexibility is in which Electric machine tool which controls electrical appliance. By exchanging the first adapter arrangement between power tool machines even a rapid change of the controlling power tool is possible. The same applies to the controlled electrical appliances. Thus, any electrical appliance can be connected to a second adapter arrangement. It may also be provided to connect several electrical appliances with only a single adapter assembly. Of course, it is also possible to control a plurality of electrical appliances simultaneously using a single power tool by using a plurality of second adapter assemblies.

In this way, it is comfortable, flexible and safe possible to take any other electrical equipment synchronously on a construction site when commissioning a specific power tool. For this it is not necessary that the power tool is powered directly from the mains. It may equally be a power tool powered by one or more accumulators or batteries. For example, when machining a workpiece with an electric saw, it is possible to transmit data to two second adapter arrangements via the first adapter arrangement, whereby the two second adapter arrangements each connect an electrical device, for example an additional light source and a suction device. Following the machining of the workpiece with the electric saw, the electric drill can now effect the synchronous connection of the light source and the suction device in a further processing of the workpiece with a drill by a simple change of the first adapter assembly of the electric saw to the electric drill. Alternatively, the additional power tool, in the example the drill, be equipped with a further first adapter assembly which controls the two second adapter assemblies.

It can further be provided that the radio module for transmitting data and / or the radio module for receiving data for operation with at least one transmission frequency and / or for operation in at least one frequency range, in particular within the ISM band, is established.

An operating range that includes multiple transmission frequencies may be advantageous to increase the flexibility of the system. As a result, a coordination of the radio modules of the adapter assemblies with each other and a consideration of local conditions, such as disturbed or prohibited frequency ranges possible. When operating the system within the ISM band (Industrial, Scientific and Medical Band), a quick and uncomplicated approval, especially in Germany, can be expected.

It may further be provided that the radio module for transmitting data and / or the radio module for receiving data for operation with at least one communication protocol is or are set up. In the present case, a communication protocol refers in particular to a radio protocol and / or a coding mode of the data transmission.

For example, it may be provided that a user of the system arbitrarily tunes the radio modules or couples with each other. Of course, a vote can already be made during manufacture or before delivery. A setting regarding the transmission frequency and / or the frequency range and / or the communication protocol can be automated by a switch position, for example a DIP switch system, an internal data memory or as a function of further radio modules located in the communication area.

Thus, it can be ensured, in particular when using a plurality of first adapter arrangements and a plurality of second adapter arrangements, that certain power tool machines only control certain electrical appliances. It could be provided, for example, that an electric drill and an electric saw at startup in each case a specially assigned suction device and simultaneously connect a common light source. Thus, the first adapter assembly of the electric drill controls a first suction device and the common light source and the first adapter assembly of the electric saw a second suction device and also the common light source. Any combinations of this kind are possible.

It can be provided that the radio module for the transmission of data and / or the radio module for receiving data can be set up to be readable to the respective counterpart. In particular, it may be provided for the first adapter arrangement to monitor, record and subsequently duplicate an independently occurring communication process between a third device and the second adapter arrangement in order to be able to control the second adapter arrangement itself - similar to e.g. is known by adaptive multifunction remote controls for media devices. Through an adaptive wireless module one or both adapter assemblies, the system can be used across manufacturers.

It can further be provided that the controllable switching device of the at least one second adapter arrangement is realized as at least one digital circuit and / or at least one analog circuit and / or at least one microcontroller. It can therefore be provided any technically known and proven measure for the realization of the controllable switching device.

In one embodiment it can be provided that the at least one first adapter arrangement has a first interface, which is formed electrically and / or mechanically compatible with a battery pack receiving interface of the power tool, and further comprises a second interface which is electrically and / or mechanically compatible with at least one interface of a battery pack is designed for the power tool and / or even has at least one battery pack. These and all subsequent developments of the invention, which relate to battery packs are of course also suitable for use with battery packs.

By such a configuration, the first adapter assembly can be used in a comfortable manner as an intermediate piece between the power tool and the battery pack. Of course, it can also be provided that the first adapter arrangement itself is designed as a battery pack and replaces an existing battery pack. Alternatively it can be provided that the at least one first adapter arrangement has a first interface, which is electrically and / or mechanically compatible with a power plug of the electric machine tool, and further comprises a second interface which is electrically and / or mechanically compatible with at least one power outlet is. The second adapter assembly can then be used as an intermediate piece between the power tool and a power outlet. Of course, therefore, all further developments described here, which relate to battery packs, also suitable for use with a mains-powered power tool.

It can be provided that the at least one first adapter arrangement has a monitoring device which is set up to indicate whether the power tool connected to the first adapter arrangement is active or inactive, and based thereon to cause the radio module of the first adapter arrangement to send data to the to transmit at least a second adapter assembly.

However, it can also be meant that the radio module transmits status data or the operating state at any time and the controllable switching device of the second adapter arrangement is controlled based on the received status data.

It can also be provided here that the radio module of the first adapter arrangement at any time or continuously status data, in particular concerning electrical supply signals and / or data signals, to the second adapter arrangement send, wherein the evaluation of the data is carried out by the latter, or transmitted only status change data.

It may be advantageous if the first adapter arrangement acts in an electrically neutral manner when used between the power tool and a battery pack of the power tool. As a result, the power tool can exchange unchanged or undisturbed data signals with the at least one battery pack and receive the electrical supply signals from the at least one battery pack without loss or interference. For detecting whether the electrical appliance is to be put into operation, which is usually to take place as a function of an operating state of the power tool, it may be advantageous to determine the operating state of the power tool by monitoring the electrical supply signals and / or data signals from the at least one battery pack , Alternatively, it can of course also be provided that the operation of an operating switch of the power tool or another switch on the power tool or a switch on the first adapter assembly is monitored.

It can also be provided that the monitoring device is set up to at least partially monitor vibrations on the power tool, an alignment of the power tool or a tilt state of the power tool.

For example, it can be easily recognized by a shake sensor or one or more acceleration sensors, whether a user wants to use or use the power tool.

It can be provided that the monitoring device of the at least one first adapter arrangement is implemented as at least one digital circuit and / or at least one analog circuit and / or at least one microcontroller.

In a further development it can be provided that the monitoring device comprises a current measuring device for measuring a current flow between the first interface and the second interface of the at least one first adapter arrangement.

When monitoring an operating state of the power tool, in particular with the aim of finding out whether the power tool is in operation or not, the current measurement represents a conceivable realization. By the current measurement can be detected whether the power tool relates electrical energy from the at least one battery pack, which indicates an operation of the power tool. Alternatively or additionally, it may also be provided to monitor electrical voltage fluctuations of the at least one battery pack, as a result of which a change in an operating state of the power tool can be concluded. It is also conceivable to use a power meter as part of the monitoring device.

In a development, the monitoring device can be designed to monitor digital control signals of the power tool and / or digital control signals of the at least one battery pack.

When using the first adapter arrangement in combination with a mains-operated power tool, it can additionally be provided an ammeter, a voltage meter or a power meter for monitoring a current flow or voltage fluctuations or a power flow between the first interface and the second interface of the at least one first To use adapter assembly.

It can be provided that the monitoring device detects the discrete operating states "on" and "off". In a development, however, it can also be provided that the monitoring device, for example based on the current measurement or the monitoring of digital control signals, detects an operating state of the power tool in many stages or even continuously and in dependence on the electrical energy consumed in the power tool. or on the basis of information which can be taken from the digital control signals, causes the radio module to transmit data in order to transmit data. An electrical appliance can then be switched on, for example, only as a function of a previously selected threshold value. A connection of an electrical appliance then takes place, for example, only when the power tool is used under full load. In this way, it can be avoided that, for example, during the application, e.g. an electric drill, in the sense of a grain marking or slight pre-drilling already an electrical appliance, such as a suction device, starts. Alternatively or additionally, a time delay or minimum operating time of the electric machine tool when connecting the electrical appliance may be provided.

It can also be provided that in the case of the at least one electrical appliance, a power control takes place as a function of the power used by the power tool.

The invention also relates to an adapter assembly for use in a system having the aforesaid features, in particular for use with a first adapter assembly according to claim 7. Of course, features already described with respect to the system may be arbitrary for the first adapter assembly, the second adapter assembly or the method can be used, and vice versa.

It is provided that the adapter arrangement is a radio module for transmitting data, a first interface which is electrically and / or mechanically compatible with a battery pack receiving interface of the power tool, a second interface which is electrically and / or mechanically compatible with at least one interface a battery pack is designed for the power tool and / or even has at least one battery pack comprises.

In one embodiment it can be provided that a monitoring device is set up to indicate whether the power tool connected to the adapter assembly is active or inactive, and based thereon to cause the radio module of the adapter assembly to transmit data to at least one second adapter assembly.

In FIG. 1 a system is shown which comprises a first adapter assembly 1 for use with a power tool 2 in the embodiment of an electric hand drill 2 and a second adapter assembly 3 for the electrical supply of at least one electrical device 4 (see. FIG. 6 ) having. Although the invention is described throughout the embodiments with reference to an electric hand drill 2, the invention is of course suitable for any power tool 2.

The second adapter assembly 3 is designed such that any 230 volt electrical appliance 4 can be used with this. Of course, the second adapter assembly 3 can also be designed such that any power-operated electric appliance 4 can be used with this. Thus, for example, a light source 4.1 (see. FIG. 4 ), a suction device 4.2 (see. FIG. 3 ), a heater, a ventilation device, a filter device or any other electrical device 4 are connected to the second adapter assembly 3. Particularly preferably, the system is used in combination with a suction device 4.2.

Of course, it is also possible to connect a plurality of electrical appliances 4, for example via a multiple socket, to the second adapter arrangement 3. The Second adapter assembly 3 may also be configured so that it can directly operate two or more electrical appliances 4.

The first adapter assembly 1 has a first interface 1.1, which is electrically and mechanically compatible with a battery pack receiving interface of the electric hand drill 2, and a second interface 1.2, which is electrically and mechanically compatible with at least one interface 6.1 of a battery pack 6 for the electric hand drill 2 is trained. The first adapter assembly 1 can thus be conveniently used as an intermediate piece between the electric hand drill 2 and the battery pack 6.

In the first adapter arrangement 1 is a radio module FM ₁ (see. FIG. 5 ) for transmitting data to the second adapter assembly 3 is provided. In order to be able to receive the data of the first adapter arrangement 1, the second adapter arrangement 3 has a radio module FM ₂ (cf. FIG. 6 ) to receive the data.

The second adapter arrangement 3 further comprises an input-side interface 3.1 and an output-side interface 3.2 and a controllable switching device 3.3 (see. FIG. 6 ). The controllable switching device 3.3 is set up to connect the input-side interface 3.1 to the output-side interface 3.2 as a function of the data received via the radio module FM ₂ , as a result of which an electrical appliance 4 can be supplied with electrical energy.

In the system, it may be provided that within the first adapter assembly 1, an operating state of the electric hand drill 2 is detected and depending on this operating condition, another electric device 4 via the second adapter assembly 3 in operation or taken out of service. Thus, for example, a light source 4.1 or a suction device 4.2 can be switched on at the same time when commissioning the electric hand drill 2.

In one embodiment, it may be provided that the adapter arrangements 1, 3 are tunable to each other, wherein, for example, a communication protocol or an encoding via DIP switch 7 at one or both adapter assemblies 1, 3 can be selected.

In FIG. 2 an alternative embodiment of the system according to the invention is shown. Features that are identical in the exemplary embodiments and have already been described in a previous exemplary embodiment will not be described again below. This also applies to all subsequent figures.

FIG. 2 shows an embodiment in which the first adapter assembly 1 serves as a replacement for at least one battery pack 6 by the first adapter assembly 1 itself comprises at least one battery pack 6.

The first adapter assembly 1 may in this case be for communication with a second adapter assembly 3 according to an embodiment as in FIG. 1 shown used. It can, however, as in FIG. 2 also be provided that a second adapter assembly 3 is used, which is not intended for use with a mains-powered electrical appliance 4, but for use with an operated by battery packs 6 or battery packs electrical appliance 4. The second adapter assembly 3 may, similar to the first adapter assembly 1 of the first embodiment of FIG. 1 be educated. The second adapter arrangement 3 can then comprise an output-side interface 3.2, which is electrically and mechanically compatible with an interface of a battery pack 6.1 or a battery pack receiving interface of the electrical device 4, for example a further power tool 2, and also has an input-side interface 3.1. which is designed to be electrically and mechanically compatible with an interface of a battery pack 6 for the electrical appliance 4 and / or itself have at least one battery pack 6. This makes it possible for a cordless power tool 2 at startup can turn on another wireless power tool 2.

It can also be provided that the adapter assemblies 1, 3 are designed to be adjustable and can optionally be used as a first adapter assembly 1 or as a second adapter assembly 3. For example, for this purpose, a switch on the housing of the adapter assemblies 1, 3 may be provided.

In FIG. 3 an inventive adapter plug 3 'is shown which is advantageously used in a system according to the invention. The adapter plug 3 'has an interface 3.1' which is formed as a 230 volt plug 3.1 'and can be plugged into a 230 volt socket 4.2.1 a suction device 4.2. It is envisaged that a suction device 4.2 is used, which automatically activates as soon as electrical energy is obtained via the 230 volt socket 4.2.1.

The adapter plug 3 'comprises a radio module FM ₂ for receiving data (cf. FIG. 7 ). It is provided in particular that one in the system described above and in FIG. 3 Not again shown first adapter assembly 1 data concerning the operating state of a power tool 2 to the adapter connector 3 'transmitted. The adapter plug 3 'also has a controllable switching device 3.3 (see. FIG. 7 ), which has a load resistance R (cf. FIG. 7 ), ie the 230 volt socket 4.2.1 of the suction device 4.2 charged with this, if the received data indicate an active operating state of the power tool 2. As a result, a mains-operated power tool is emulated by the adapter plug 3 'at the 230 volt socket 4.2.1 of the suction device 4.2. It can therefore be made even with a suction device 4.2, the compatibility with the system of the invention, which is basically intended for use with a mains-powered power tool.

It may be necessary for the adapter plug 3 'to be in an operating state in which the power tool 2 is not in operation or in which the adapter plug 3' is in standby mode, ie in an operating state in which the load resistance R not connected to the 230 volt socket 4.2.1, draws electrical energy from the 230 volt socket 4.2.1 of the suction device 4.2, to provide itself electrically. It must be ensured that the electrical energy required for this purpose is below a threshold value above which the suction device would activate 4.2.

In FIG. 4 is a further embodiment of a system according to the invention shown. It is provided that a second adapter assembly 3 in the embodiment of FIG. 1 in a 230 volt socket 4.2.1 a suction device 4.2 of an embodiment of FIG. 3 is inserted. Finally, another electrical appliance 4, in the exemplary embodiment a light source 4.1, can be connected to the second adapter arrangement 3.

This arrangement has the consequence that the second adapter assembly 3 upon receipt of a data signal from a first adapter assembly 1, which indicates an active operating state, such as an electric hand drill 2, the light source 4.1 switches on by this with the 230 volt socket 4.2.1 of the suction device 4.2 is connected by the controllable switching device 3.3. Due to the fact that the light source 4.1 draws electrical energy from the suction device 4.2 as a result, the suction device 4.2 simultaneously turns on. Thus, the electrical energy that must be related to the emulation of a mains powered power tool on the suction device 4.2, can be used meaningfully.

In FIG. 5 is schematically and exemplified a circuit diagram of a power tool 2, the first adapter assembly 1 and a battery pack 6 shown. The diagram shows a consumer M of the power tool 2, which in response to a mechanical switch 8 via the battery pack 6 electrically can be operated.
