Description

Functional element and tool system

Technical Field

The present invention relates to a functional element for storing and/or transporting objects. Furthermore, the utility model discloses still relate to a tool system.

Background

Electric hand-held power tools are known in principle and are supplied with current via a mains connection. Alternatively, the battery device can achieve a high flexibility in operation, since the battery device is not dependent on the grid current in particular. In this way, for example, outdoor work can also be carried out easily, so that it is often provided that a battery pack is used when the hand-held power tool is in operation.

Such battery packs are known in principle and usually have a plurality of rechargeable battery packs connected in parallel and/or in series, for example three cylindrical lithium-ion cells connected in series, for example each having 3.6V, with a total voltage of 10.8V. In order to charge the battery pack, the battery pack must be connected to a charger, wherein the charger receives the current required for charging the battery pack via a network connection. Here, the charger is usually a plug that is inserted into a socket.

Chargers for lithium-ion rechargeable batteries are known in a large number of embodiment variants. These chargers typically have at least one combined mechanical and electrical interface. There, the battery pack remains in place during the charging process. Furthermore, chargers are known which comprise a plurality of charging contacts, wherein each charging contact is configured for connecting a battery pack to a battery charger. The charger may not only be of a desktop embodiment, but may also be of a transportable variety with or without a handle.

As long as the current source is available, the charger is often carried to the location of use of the hand-held power tool or at least in the vicinity thereof. In this case, it is often considered to be a disadvantage that the appliance only takes up space during the time when the battery is not being charged, but there is no other use for the user.

In chargers having more than one interface for charging the battery pack, often not all interfaces are used simultaneously, so that customers who expect not to always use all interfaces for charging tend to purchase chargers having fewer interfaces, although in some cases more charging interfaces may be desired.

Disclosure of Invention

The object of the present invention is to improve the above-mentioned disadvantages and to provide a charger of the type mentioned at the outset for charging a battery pack of a hand-held power tool, which charger prevents the mentioned disadvantages to the greatest possible extent and brings about other uses for the user in addition to the charging function.

This object is achieved by a functional element for storing and/or transporting objects. Advantageous configurations, variants and further developments of the invention are explained below.

The functional element for storing and/or transporting objects according to the invention comprises a base body and at least one first interface, wherein the first interface is designed in such a way that the functional element can be mechanically connected to a first mating interface of a charger. The functional element can be designed as a cartridge, an adapter plate or the like, for example, which can receive objects, such as tools, tool parts and/or fittings.

Thus, the charger may be used for other purposes in case more than one charging interface is available or also during charging, which increases the availability and the attractiveness of the charger in the eyes of the user.

In a preferred embodiment, the first interface is designed in such a way that the functional element can be electrically connected to the first mating interface of the charger and/or the first mating interface of the hand-held power tool. Thus, for example, electrical consumers, such as light-emitting means, for example diodes, for illuminating the area of the functional element can be connected to or in the functional element, which results in additional use of the consumer.

Advantageously, the base body is designed in the form of a container and defines a receiving volume for receiving the object. In this general form, the functional element constitutes an extension of the functionality of the charger that can be used by the user for different applications, for example as a receptacle for small parts or as a storage compartment.

In one embodiment, the base body comprises an access opening for accessing the receiving volume. Depending on the field of application, i.e. depending on the type of object to be received, the base body can be designed as a cylindrical, box-shaped or spherical container, wherein generally triangular, quadrangular, pentagonal or n-sided containers are also conceivable.

In a further embodiment, the base body has at least one separating element for dividing the receiving volume. The separating element can be, for example, a removable, user-adaptable or fixedly mounted insert.

In one embodiment, the functional element has a closure or a cover for closing the access opening. In this way, small parts can be prevented from falling out. Alternatively, a clamping element can be provided, by means of which falling out can be prevented.

In one embodiment, the base body has a plurality of individual insertion openings, wherein each individual insertion opening is arranged in such a way that different objects can be received in a form-fitting manner. For example, the insertion opening can be configured for the form-locking reception of a tool bit, a drill bit, a jigsaw blade and/or a GOP/PMF cutting blade (e.g., of this type)

Model number). Furthermore, the functional element can be used in this form as a sleeve (Holster), for example, for a screwdriver or a hammer.

In one embodiment, the base body comprises at least one receiving element for the form-locking reception of at least one object, in particular a batch head holder. In this embodiment, the receiving element, which may be referred to in the broadest sense as a gripping element or an elastic collar, may receive objects of different shapes and sizes.

In one embodiment, the base body is designed as an adapter element, which comprises at least one further interface for receiving a receiving element or container to be adapted, in particular a mating interface of a batch head holder.

The adapter therefore offers great advantages to the user, in particular for mobile use purposes, wherein a charger with a plurality of vertically standing battery pack connections and a carrying handle is particularly well suited. This principle is similar to a portable conventional carpentry gear box, wherein the user can individually select the holding device or container to be adapted, depending on the need and the number of battery pack interfaces that are free.

Another advantage to the customer is that the customer can carry the charger with them as well as the battery pack, power tool and accessories. The different storage boxes, cassettes, etc. carried along can be replaced by one or more functional elements according to the invention. When different small parts are required empirically, they can be carried in or on the functional element, which is particularly advantageous when minor repair and maintenance work is to be carried out at different locations.

In one embodiment, the first interface is designed as a battery pack rail, so that the functional element can be axially plugged onto the first mating interface. In another embodiment, alternative connection types are used, such as snap-in connections, flip-chip connections (kipperbudung) or plug-in connections.

In this way, a secure fastening of the inserted battery pack and/or the charger latched in the holding device can be ensured, as a result of which, for example, the use of the charger in high-rise buildings can be achieved. In one embodiment, the charger is fixed to the horizontal plate by means of the holding device in the sense of a table assembly, as a result of which the battery packs inserted in the charger are better protected against unintentional falling than battery packs lying in a scattered manner.

The functional element is preferably at least partially made of an engineering plastic, wherein the functional element in certain embodiments is multi-component with respect to the material used and comprises, for example, an engineering plastic (TPE), a rubber coating and/or a metal component for surface protection.

According to another aspect, the invention comprises a tool system comprising at least one charger having at least one first mating interface for electrical and mechanical connection to a corresponding battery pack, the tool system further comprising the functional element described above, which comprises the first interface, wherein the first interface is configured such that the functional element can be mechanically connected to the first mating interface of the charger.

Advantageously, the functional element is electrically connectable with the first mating interface of the charger.

In one embodiment, the charger comprises a plurality of first mating interfaces, in particular a plurality of battery pack interfaces, which stand vertically in normal use.

Preferably, the charger has a carrying handle for transportation.
