Description

The invention relates to a container for storing at least one device driven by an accumulator, having a housing and having a power supply for charging the at least one accumulator.

Under a housing is understood in the context of the invention, a unit that meets the stated purposes. Preferably, the embodiment is a closed suitcase that can be opened for use. This embodiment is preferably used in the context of this description. The container is then mainly formed by the closed housing. In addition, however, the housing may also have open sections or be formed overall as an open frame or carrier. In this case, inside the housing, for example, the electronics and other components to be protected are arranged, while the devices are directly accessible from the outside, without the housing must be opened. The container in this case comprises a partially open and partially closed housing.

A generic container or case is for example from the prior art of DE 10 2012 111 328 A1 known. The case shown here initially has a housing and a lid pivotally connected thereto. A central power supply with rectification of the voltage is provided for example for four different electrically driven tools. Common to these devices are an electric drive and / or an electronic control, which are powered by an accumulator with electrical energy.

The devices thus each have an accumulator and possibly also a separate charger for generating and monitoring a charging current, so that only a contact with a DC voltage is sufficient to perform a charging process.

The housing or the case thus has itself only electrical contacts for the transmission of the charging current to the accumulator driven tool. For this purpose, two contacts are preferably provided in each case, namely a ground contact and a contact with voltage level, such as 4 volts, 6 volts, 9 volts, 12 volts, etc. The DC voltage applied here is generated by means of suitable rectifier electronics from a mains voltage, via a conventional power plug is supplied to the container.

By default, the battery-powered hand-held devices described above are charged with a male-female connection. Also known are connections with spring contacts in the charging cradle and with fixed contacts on the device side. However, these are not transportable and have the problem that when a position deviation from the horizontal bad contact or an indifferent contact (contact / no contact) may occur. These bad contacts can then lead to a strong heating of the contacts because of a high contact resistance and / or because of the formation of tearing sparks in a loose contact.

In addition, the variability of the container can be further improved. Since the container is provided with a power supply, other, for example, for the DIY sector interesting devices can be operated.

From the GB 2 397 704 is also a case with a power supply for charging a battery known. It is an anti-theft device with a motion sensor and a siren attached to the case, the siren is triggered in an unauthorized movement or unauthorized opening of the suitcase.

In the US 5,148,150 discloses an alarm system for portable containers, such as files and handbags, which is triggered by a sensor during a sudden movement or a change in position of the file or handbag.

From the DE 297 08 343 U1 is a tool and accessory cart known in which can be housed in boxes and tools accessories, the load boxes are interchangeable.

The present invention is therefore based on the technical problem of further improving a container for storing at least one device driven by an accumulator and / or to make it more variable.

The technical problem is solved according to the invention by an initially mentioned container for storing at least one device driven by an accumulator in that a tilt sensor fixedly connected to the housing is provided for detecting the orientation of the container in the room.

With the help of the tilt sensor according to the invention thus the position of the housing is determined in space and the tilt sensor generates a characterizing the situation in the room output signal. Based on the output signal devices and means that are connected to the housing can be controlled differently.

In a preferred manner, the inclination sensor is designed as an electronic position or acceleration sensor. These are known for example from the application in smartphones and are regularly designed as a gyroscope. With the help of such a sensor can be reliably and quickly determine the orientation in space relative to the direction of gravity. In this case, the inclination sensor is preferably arranged and fastened on a circuit board of the power supply or at another point in or on the housing of the container.

Furthermore, it is alternatively possible to form the inclination sensor as a mechanical sensor. In this case, individual moving weights and their movement are utilized to mechanical switching operations.

Before using the inclination sensor with the container, it is necessary to calibrate its orientation relative to the orientation of the container or to a reference surface, in particular the underside of the container. Then, if the position of the tilt sensor relative to the container is no longer changed, the one-time calibration can ensure accurate alignment of the tilt sensor.

In a preferred embodiment of the present invention, a switching means for interrupting the power supply in dependence on by the Tilt sensor determined orientation of the container provided in the room. As a result, the operation of the container can be secured as a charging station for the at least one device when the housing assumes an oblique position. For a portable housing can with a charging device, such as a charging tray with spring contacting the loading of the inserted devices, only in a very defined position, for example, on a flat surface to allow a defined slope. If the housing with the described charging function is located on a more inclined surface, or if the housing is moved in such a way that an inclination occurs, the inclination sensor will interrupt the provision of charging current and charging voltage. This measure ensures the operation of the charging function of the housing in the appropriate position.

The switching means preferably interrupts the power supply when the tilt sensor signals a predetermined angular deviation from the horizontal. Examples of given angular deviations are 10 ° or 20 °.

With the above-described defined interruption or shutdown of the charging function in case of improper use of the housing, for example, when parking on an excessively inclined surface, possibly above a predetermined angle, a safe charging is guaranteed under normal use. This measure thus provides additional security for loading in a previously described container.

If the tilt sensor again indicates an incline within the allowable range, then the power can be turned on again either automatically, possibly with a time delay, or manually by the user.

Furthermore, an optical and / or acoustic display for indicating the interruption of the power supply can be provided. Typically, LEDs are provided to indicate the charging process. For example Red when no charge occurs because no device is inserted, and green when charging and yellow when charging is complete and the connected battery is fully charged. The display of the interruption of the charging process with the device inserted because of a deviation from the horizontal can then be indicated by a flashing red or green signal. In addition or as an alternative, an acoustic signal can also be output, if appropriate only briefly, in order to audibly indicate the interruption of the charging process.

In a further preferred embodiment of the present invention, a leveling laser is provided, wherein in at least one working position of the leveling laser, a fixed angular relationship between the inclination sensor and the leveling laser and wherein the leveling laser is controllable with the output of the inclination sensor as a reference value for the orientation in space.

A leveling laser is understood to mean a unit which comprises at least the optical components and their motor systems, which can be controlled by means of control electronics. The control electronics can be arranged wholly or partly within the unit of the leveling laser, in particular within an associated housing.

Leveling is the process of detecting and compensating for elevation differences or precisely aligning multiple points on a line. Such devices are already known, but they are only provided as separate, standalone devices.

The preferred embodiment of the invention now proposes to develop the container for storing at least one device driven by an accumulator with an inclination sensor in such a way that the signal of the inclination sensor is used to support a leveling laser to control a craftsman when mounting various objects on walls, ceilings or floors. This leveling laser then requires no inclination sensor itself and can be made cheaper as an accessory.

Furthermore, the leveling laser can have the optical and motor components and the control electronics can be arranged at least partially outside the leveling laser and inside the housing. Thus, a part of the control electronics or the entire control electronics is outsourced from the housing of the leveling laser and disposed within the housing of the container. For this purpose, the board can be used in the power supply or a separate board arranged in the housing. Thus, the unit of the leveling laser or its housing may be smaller in size and easier to be arranged in or on the housing. Preferably, the leveling laser essentially only has the optical and motor components that can be controlled by means of supplied electrical signals from the control electronics arranged in the housing.

In particular, when the inclination sensor is also used for the monitoring of the charging of the at least one device described above, the already existing inclination sensor can be used in two ways. Thus, synergies are exploited that can not arise in independently operating devices and containers.

Advantageously, the leveling laser is firmly connected to the housing, so that the working position is fixed relative to the housing. Thus, the housing itself, together with the inclination sensor fixed thereto, predetermines the reference orientation for the leveling laser.

In a further development of the container according to the invention, the leveling laser is arranged within the housing and projects a laser beam outside the housing when the housing is open. Thus, the leveling laser within the Housing are covered in a fixed working position relative to the housing, so that after opening the housing of the leveling laser at least partially protrudes from the housing, in particular above the edge of the container, in particular a lower part of a suitcase and can project the leveling laser beam in the direction outside of the container ,

In a further development of the container, the leveling laser is arranged within the housing and projects a laser beam outside the housing when the housing is closed. For this purpose, the housing may have a window or a free opening for the passage of the laser beam. Thus, the container in closed form can serve as an alignment aid.

In a further development of the container, the leveling laser is connected with a facial expression and connected by means of facial expressions and retractable connected to the housing, wherein the leveling laser occupies a fixed angular relationship to the tilt sensor in at least one of the two end positions of the facial expression. Thus, the leveling laser can be extended out of the housing when it is to be used. If the leveling laser, however, is unused, it may be retracted or folded and remain within the housing.

In a further development of the container, the leveling laser is removable and connectable to the housing and the leveling laser assumes a fixed angular relationship to the inclination sensor in the fixed position as a working position. Thus, the leveling laser is only connected to the container when in use and otherwise can be stored separately. For example, the leveling laser can be fixed in or on the housing in a predetermined position by means of a screw connection, a bayonet connection, a magnetic connection or another connection technique such that in this working position of the leveling laser there is a fixed angular relationship between the inclination sensor and the leveling laser.

By mounting the leveling laser and electrical contacts for transmission of the output signal of the inclination sensor, for a suitable power supply of the leveling laser and possibly for the control electronics generated within the housing produced control signals for the leveling laser. In particular, in this case, it is advantageous to arrange the control electronics of the leveling laser within the housing, because thereby the detachable leveling laser can be dimensioned smaller as an accessory.

Furthermore, the housing can advantageously have a thread for attachment to a stand. Thus, the container can be brought and held in a determined vertical, horizontal or oblique position. In this case, a conventional tripod, in particular a photo tripod can be used.

In a further and independent of the previously described inventive embodiments of the container embodiment, the above-mentioned technical problem is solved by a container for storing at least one device driven by an accumulator with a housing and with a power supply for charging the at least one accumulator, that the Housing itself has a battery and thus, if no connection to an external power supply is possible, at least for a limited period of time can serve as a charging station. Thus, the accumulator can supply the at least one rechargeable device and / or the leveling laser temporarily with electrical energy, without the need for an external power supply.

The advantage of this solution is that the container can be used even when working outdoors or on construction sites without power supply for a long time for charging at least one device, without having to rely on an external power supply. Preference is given to the arrangement of a Switching means for selecting a particular device for charging, whereby the capacity of the additional accumulator can be used selectively.

Furthermore, in each of the previously explained embodiments, the housing can have at least one electronic connection, in particular a USB connection, which is connected to the power supply and / or to the accumulator. Thus, any devices, especially mobile phones, smartphones, music players or other devices can be connected and operate independently of their own state of charge. Thus, even with prolonged use of the container, for example in a renovation, regardless of a power supply, the user can use his consumer electronics.

The container according to the invention has previously been explained with reference to preferred embodiments. The devices driven by an accumulator devices have not been explained in detail, since it does not depend on the type of device in principle.

The devices can be tools such as a hot melt gun, a stapler, a cutting tool, a sawing tool, a grinding tool, a drill tool or a screwdriver tool. In this case, the screwdriver tool on a tool holder for receiving a drill or a screwdriver bit.

In addition, the devices may also be a flashlight, a heating or cooling device, or any temperature measuring device, for electrical quantities such as voltage, current and resistance, or a length measuring instrument.

Common to these devices is that they are powered by electrical energy stored in an accumulator. The container can also have other devices that do not require electrical energy, as well as other materials.

In the Fig. 1 to 6 an inventive container in the form of a suitcase 1 is shown, which will be explained below. Trained as a tool case suitcase 1 has a suitcase base 2, which may also be referred to as a housing, and a suitcase top 3, which may also be referred to as a lid. The suitcase bottom 2 and the upper case 3 are pivotally connected to each other via hinges 4.

In the case 1, as is apparent Fig. 3 results, holding receptacles 5 are provided, each holding an accumulator operated tool 6, 7, 8 or 9. By way of example, the tools are a hot melt gun 6, a drill or screwdriver tool 7, a stapler 8 and a cutting tool 9.

In the case bottom 2 is further (see Fig. 6 ) a charging station 10 is provided, which is supplied with a mains cable 11 with a mains voltage. The mains voltage is converted in the charging station 10 in a voltage required for charging the batteries. The holder receptacles 5 each have associated charging contacts 12, with which the converted voltage is transmitted. Optionally, further control and / or signal lines are connected to the charging contacts 12.

The charging contacts 12 are aligned upward freely in the holder receptacle 5 for contacting tool-side (not shown) charging mating contacts.

As it turned out Fig. 3 shows, in the case base 2 of the case 1, an inner bottom 13 is formed, in which the holder receptacles 5 are formed. The inner bottom 13 is preferably flush with a further trained on the case base 2 circumferential Side wall 14 of the case 1 is formed. The removal of the inner bottom 13 is according to Fig. 6 shown only to illustrate the construction of the case 1.

Below the inner bottom 13, an outer bottom 15 of the case base 2 is provided. The inner bottom 13, the outer bottom 15 and the side wall 14 thus define a gap 16, see Fig. 5 ,

In the intermediate space 16, the power cable 11 are arranged together with an optional winding station 17 for the power cable 11, the charging station 10 and the individual support receptacles 5 associated charging contacts 12, wherein the charging contacts 12 preferably extend as only to the outer surface formed by the inner bottom 13.

The tools 6, 7, 8 and 9 are configured angled in their extension direction E running. The tools 6, 7, 8 and 9 are received in the holder receptacles 5 in such a way that the angled portion 18 is pointing downwards in the holder receptacle 5. At the case base 2, a carrying handle 33 is also provided.

Furthermore, one or more ventilation openings 19 and 20 are provided in the side wall 14 and in the outer bottom 15. Thus, a gap 16 passing through the air flow L can result. For this purpose, one or more of the ventilation openings 20 are formed in the outer bottom 15 and one or more of the ventilation openings 19 in the side wall 14. The ventilation openings 19 are thus in the specified state of use also higher than the ventilation openings 20. Further, in the case 1, a motor operated fan unit (not shown) may be provided.

The ventilation openings 19, through which the air flow L preferably exits, see Fig. 5 , are preferably associated with the back of the case 1, on which also the hinges 4 are formed.

On the inside of the upper case part 3 and / or in the lower case part 2 receptacles or holders 21 may be provided for other devices, tools, items, documents or consumables.

Fig. 7 shows in cross-section in detail the arrangement of the charging station 10 within the case 1. About the cable 11, the mains voltage is transferred to the charging station 10 and transferred to a circuit on a circuit board 23. The circuit is symbolically provided with components 24 which perform certain electrical functions to generate from the mains voltage a DC voltage of either 4 volts, 6 volts, 9 volts or 12 volts. This DC voltage is then forwarded to the charging contacts 12.

Fig. 7 further shows an inclination sensor 30 according to the invention, which is arranged and fixed within the charging station 10 on the board 23 contained therein. The tilt sensor 30 is designed as an electronic position sensor or as an electronic acceleration sensor. Inclination sensors are precision mechanical or electrical measuring devices which, for electronic devices, for example for an instrument or vehicle frame, make an exact reference to the direction of the perpendicular, monitor deviations from the direction of the perpendicular or changes in the inclination angle and display them in the form of electrical signals.

Such tilt sensors are commercially available and are used for example in smartphones and other electronic devices for position positioning and position control. As a rule, the inclination sensor 30 is a gyroscope which functions as a gyroscopic sensor and, at the same time, can detect an inclination, a linear acceleration and / or a rotation as a motion sensor.

With the help of the tilt sensor 30 so the relative position of the suitcase 1 in space or to the perpendicular can be determined. Since the tilt sensor 1 firmly with a Component of the case 1, that is in the present case connected to the permanently installed board 23, the orientation of the case 1 can be determined. Optionally, the positioning of the tilt sensor 30 must be calibrated relative to the board 23 or relative to the case 1 prior to its use.

If the case 1 with feet 22 is then placed on a base, the measured position of the suitcase 1 results in a measured value of the inclination sensor 30. Preferably, three feet 22 are arranged on the underside 15 of the case 1 in order to be able to move on uneven surfaces ensure wobble-free arrangement of the case 1.

Furthermore, a switching means 32 for interrupting the power supply, either the mains voltage or the DC voltage depending on the determined by the tilt sensor 30 orientation of the case 1 is provided in the room on the board 23. Thus, the tilt sensor serves as a security protection means for the use of the case 1, when the case 1 is placed on an oblique or otherwise unsafe pad.

In this case, the switching means 32 interrupts the power supply when the tilt sensor 30 signals a predetermined angle deviation from the horizontal. This value is fixed or can be adjusted as needed. Preference is given to angles of 10 ° or 20 °, from which the interruption of the power supply takes place.

As Fig. 3 Alternatively, the tilt sensor 30 may also be connected to the inner bottom 13 and be connected by means of a suitable line to the power supply or the switching means 32.

Furthermore, as in Fig. 1 . 4 and 6 can be seen, a visual display 36 with LEDs 37 and an acoustic display 38 in the form of a small speaker to indicate the interruption of the power supply provided. If the Power supply is interrupted due to the signal of the inclination sensor, a specially provided for this case LED (LED) 37 or an otherwise used light source or the speaker can be controlled to signal this operating state. Thus, the user is informed when the power supply is interrupted so that he can check the position of the case 1 and also the position of the devices in the mounting receptacles 5 and readjust. This ensures safe operation of the case 1.

In a further embodiment of the invention, the container or case 1 has a leveling laser 40. A leveling laser provides a simple measure of flatness and leveling with a self-aligning, rotating laser. The laser is, for example, projected onto a wall, so that a horizontal, vertical or at a predetermined angle extending light line can be seen. At this light line can then, for example, the position of boreholes, nails to be introduced and other manual measures are determined. It is also possible to use leveling lasers to display directly spaced points along an aligned line so that even an additional measurement can be dispensed with.

At least in one operative position of the leveling laser 40, there is a fixed angular relationship between the tilt sensor 30 and the leveling laser 40, with the leveling laser 40 being controllable with the output of the tilt sensor 30 as a reference for spatial orientation and aligning the projected laser beam thereafter.

In the following, various embodiments of containers 1 according to the invention with a leveling laser 40 based on 8 to 11 explained in more detail.

Fig. 8 shows an embodiment in which the leveling laser 40 is fixedly connected to the housing of the case 1, in this case with the case bottom 2 and with the inner bottom 13. Thus, a fixed angular relationship between the Leveling laser 40 and the case 1 made so that the alignment of the laser can be done reliably.

This is according to Fig. 8 the leveling laser 40 disposed within the housing, so the suitcase base 2 and projected with the case open, so when unfolded case upper part 3, a laser beam outside the housing. For this purpose, the upper part 42 of the leveling laser 40 protrudes upward beyond the edge of the side wall 14, through which the laser beam of the leveling laser 40 is emitted. When the housing is closed, the upwardly protruding part of the leveling laser 40 is received by a corresponding recess 42 in the case top 3.

At the in Fig. 8 leveling laser 40 shown, both the optical and motor components and the control electronics within the leveling laser 40 are arranged. Therefore, this leveling laser has a certain size.

According to the embodiment according to Fig. 9 the leveling laser 40 does not protrude beyond the edge of the side wall 14, so that the leveling laser 40 is disposed within the housing consisting of the case bottom 2 and the case top 3 when the case 1 is closed. In this position, the leveling laser 40 projects a laser beam out of the housing through a window 44 disposed in the side wall 14.

In this case, the leveling laser 40 has the optical and motor components, while the control electronics are located outside of the leveling laser 40 and inside the housing 2, 3 on the power supply board. The electrical signals generated in the control electronics are then supplied to the leveling laser 40 via corresponding lines. Therefore, the leveling laser 40 can be compared to that in FIG Fig. 8 be shown to be made smaller leveling laser.

In this case, the leveling laser may also be disposed within the space 16. Thus, a previously unused space could be used and a part of the installation space above the intermediate floor 13 would remain for the recording of other tools and / or materials.

At the in Fig. 10 illustrated embodiment of the leveling laser 40 is connected to a facial expression 50 and connected by means of the facial expressions 50 and retractable connected to the housing of the case 1. It is in Fig. 10 the facial expression 50 shown in its unfolded position. The mimic 50 can, for example, be retracted and extended by turning a spindle 52 and thereby adjust the distance of the leveling laser 40 to the case bottom 2 or to the inner bottom 13.

It is ensured that the leveling laser 40 assumes a fixed angular relationship to the tilt sensor 30 in at least one of the two end positions of the facial expression 50. This is ensured by an appropriately trained mechanism, possibly with latches.

At the in Fig. 11 In the illustrated embodiment, the leveling laser 40 is detachable and connectable to the case of the case 1, ensuring that the leveling laser 40 in the secured position assumes a fixed angular relationship with the tilt sensor 30. Thus, the leveling laser 40 for use with the case 1 can be selectively connected or detached therewith. This is in Fig. 11 illustrated that a thread 45 is disposed in the inner bottom 13, in which a provided on the leveling laser 40 thread 46 can be screwed.

Furthermore, the housing, in the present case, the case bottom part 2, a thread (not shown) for attachment to a tripod (not shown). This allows the case 1 and thus the leveling laser 40 to be determined in one Height or position are arranged to project a corresponding laser light line to one or more walls.

Another independent embodiment of the present invention is disclosed in Fig. 6 shown. Here, the container already explained above, or the case 1 for storing at least one device 6, 7, 8 and / or 9 driven by an accumulator, has a housing and a power supply for charging the at least one accumulator. According to the invention, an accumulator 70 is provided in the housing, in the present case in the case lower part 2. This accumulator 70 is charged during connection to a mains voltage by means of the power cable, so that the accumulator 70 during operation out of reach of a socket, the at least one device 6, 7, 8 and / or 8 and / or a leveling laser 40 temporarily with electrical energy can provide.

In particular, at least one switching means can be provided, with which it can be selected which of the current-dependent devices is supplied with current from the accumulator. Thus, the energy from the accumulator can be used selectively.

In a further embodiment, the housing of the case 1 has at least one electronic connection 80, in particular a USB connection, which is connected to the charging station 10 and / or to the accumulator 80. Thus, electronic devices, in particular from the telecommunications and entertainment technology, such as smartphones and music players can be powered while a user is busy for a long time with manual work.
