Definitions

• the invention is based on a case with a first receiving bay for a battery-operated power tool with the generic features of claim 1.
• Cases which have one or more receiving bays for battery-operated power tools.
• the power tool can be accommodated in this either together with the battery that operates it or separately from it. This simplifies the transport of a battery-operated power tool. To charge the battery, however, it must be removed from the case and connected to a charger. If the battery is still inserted in the power tool, the power tool must be removed from the case and the battery must then be removed from it. This is time consuming.
• the battery can be charged when plugged in.
• this is a small vacuum cleaner with a 1 wall bracket, a drill with machine holder for wall mounting and a cordless screwdriver with wall bracket and charger. This does reduce the effort involved by removing the battery from the electrical device, but the electrical device is not well protected against environmental influences during charging. In addition, the electrical device is difficult to move from one place to another.
• a transport case according to the invention with the features of claim 1 has the advantage over the fact that a battery-operated power tool together with the inserted battery can be charged in a closed transport case.
• the work is battery. is plugged into the battery-operated power tool, connected to the charger via a first line when it is inserted into the receiving bay.
• This charger receives the power required to charge the work battery via a mains connection device that can be connected to a power source. This is usually a plug that is inserted into an electrical outlet. This allows the power tool's rechargeable battery to be charged while the power tool is stored safely. It is not even necessary to remove the working battery from the power tool. It is only necessary to ensure that the working battery has external contacts which, in the inserted state of the power tool in the first receiving bay, are in contact with corresponding contacts in the first receiving bay.
• a preferred embodiment of the transport case provides that the mains connection device has a plug which is arranged on a cable and rolls on a cable reel-up device.
• the transport case can also be at a distance from the power source that the power Power supply to the charger inside the transport case. This results in greater flexibility for the owner of the transport case.
• the cable reel-up device is arranged inside the case and exerts a force on the connector which pulls it into an external connector garage. This ensures that the plug is always pulled back into the transport case when it is not connected to a power supply unit by a fixed connection. This means that the cable does not have to be continuously wound up by hand.
• the charger is connected to an external charge status display which shows the charge status of at least one working battery or replacement battery located in a receiving bay and / or charging bay.
• an external charge status display which shows the charge status of at least one working battery or replacement battery located in a receiving bay and / or charging bay.
• the mains connection device is designed as a first plug contact which can be connected to a second, inverse plug contact on a further case designed according to one of the preceding claims.
• the mains connection device is designed as a first plug contact which can be connected to a second, inverse plug contact on a further case designed according to one of the preceding claims.
• the single figure shows the schematic structure of a transport case according to the invention.
• a transport case 1 for a battery-operated power tool 3 has a first receiving bay 2 for receiving the power tool 3.
• the power tool 3 can be inserted into the receptacle 2 with an inserted working battery 4.
• Contacts (not shown) are arranged on the receiving bay 2 and are in contact with contacts on the working battery 4 (not shown) when the power tool 3 is in the inserted state. These contacts are connected to a charger 6 via a first line 7.
• the charger 6 is connected to a mains connection device 5.
• the mains connection device 5 is a plug 8, which is attached to a cable reeling device 10 via a cable 9.
• the plug 8 is pulled into a plug garage 11 on the outside of the transport case 1 by a force, usually a spring force, which the cable reeling device 10 exerts on the cable 9.
• a force usually a spring force
• This principle is comparable to that known for vacuum cleaners.
• the plug 8 is pulled out of the plug garage 11 against the force of the cable retractor .10 and plugged into a socket.
• the charger 6 thus receives the current required to charge the working battery 4.
• the charger .6 is connected to a charge status indicator 15 attached to the outside of the transport case 1.
• the charge state of the working battery 4 can thus be checked continuously.
• the user of the transport case 1 is therefore protected from a surprise when he wants to use the power tool 3 and this cannot be put into operation due to an empty working battery 4.
• the carrying case 1 also has two charging bays 12, 12a, each for a replacement battery 13, 13a.
• the charging bays 12, 12a and the replacement rechargeable batteries 13, 13a are each provided with interacting contacts (not shown).
• Charging bays 12, 12a are also each connected to the charger 6 via further lines 14, 14a.
• a separate charge status indicator 16, 16a is provided for each of the two charging bays 12, 12a. These act like the charge status display 15 described above for the working battery 4 it is possible not only to charge the working battery 4 of the power tool 3, but also two spare batteries 13, 13a at the same time. This ensures that the power tool 3 can be used significantly longer, since the empty working battery 4 can be replaced by a replacement battery 13, 13a, which can always be carried in the transport case 1 easily and safely packed.
• the power tools 3 can be a drill, a screwdriver and / or a vacuum cleaner. It is also possible to provide a different number of charging bays 12, 12a in the transport case 1 instead of two charging bays 12, 12a for replacement batteries 13, 13a. This depends on the size of the transport case 1 and the intended operating times for the power tool or tools 3.
• the exemplary embodiment according to the invention described above has further advantages: on the one hand, no additional wall bracket is required for charging the power tool 3, and on the other hand it is a very good periphery for sets from battery-operated electrical appliances 2, so-called combos. Furthermore, on a construction site, you have all the required battery-operated power tools 2 at hand in a single transport case 1, with a simultaneous recharging of replacement batteries 13, 13a while working with the work battery 4. In addition, charging the electrical tools 3 with very little space required in the workshop gal take place, the power tools 3 being very well protected against environmental influences.
• plug contacts are advantageously designed as plug contacts which are inverse to one another and which are embodied in a fixed manner or also on the transport case 1 by means of a cable reeling device described above.
