Description

[0001] The invention relates to a container for detachable attachment to a battery of a hand tool, an arrangement consisting of a battery and a container, and a battery-powered hand tool.

[0002] When working with power tools such as cordless screwdrivers, jigsaws, or routers, it's advantageous to have a selection of different tools readily available, including bits, drill bits, countersinks, saw blades, and other suitable attachments. These are often carried in a trouser pocket or kept in a separate box that's placed nearby during work. However, experience shows that such boxes are often not immediately accessible when you want to change tools. Furthermore, depending on the work situation, it can be inconvenient to have to retrieve the box first to change tools.

[0003] One object of the present invention is to simplify work with a battery-powered hand tool.

[0004] This problem is solved by the subject matter of claim 1. Advantageous further developments are the subject matter of the dependent claims and are described in the description and the drawings.

[0005] The container according to the invention is designed for detachable attachment to the battery of a hand tool. For this purpose, the container has a mounting section for detachable mechanical attachment of the container to the battery.

[0006] The term "removable" is understood to mean that the container can be attached to and detached from the battery, particularly without tools. It is clarified that the attachment is mechanical, which includes, in particular, positive-locking and / or friction-locking connections. Specifically, the container and the battery can also be connected by a combination of positive-locking and friction-locking connections. This allows for quick and easy attachment of the container to the battery, especially without tools. As a result, the container can always be within easy reach and in a defined location while working with a hand tool, making it quickly accessible and enabling rapid tool changes. The design according to the invention also allows for a small and lightweight construction.Due to its positioning on the battery, the container does not affect the feel of the cordless screwdriver during use.

[0007] The container can be designed to slide onto the battery. This means that the container is attached to the battery using a linear, sliding motion. This is a particularly simple way to attach the container to the battery.

[0008] The mounting section can have at least one rib for engaging with a groove or shoulder on the battery. This engagement creates a positive connection that helps to securely hold the container to the battery. At the same time, the groove or shoulder can also serve as a guide for the rib when, for example, the container is slid onto the battery.

[0009] Preferably, the mounting section has a side wall with at least a first side wall section and an opposing second side wall section, wherein the two side wall sections are designed for a friction-fit connection with the battery when the container is attached to the battery. In the attached state, the side walls can abut opposite sides of the battery.

[0010] The two side wall sections can limit a space for the battery, so that the side wall sections can clamp the battery between them.

[0011] The side wall can be made of plastic, for example, polyamide. The plastic can contain glass fibers for reinforcement. For example, the material PA6GF30 can be used. This ensures that the side wall is soft enough to flex slightly when the container is slid onto the battery, making it easy to attach, but also strong enough to create a secure connection between the container and the battery by generating sufficient clamping force.

[0012] Preferably, the side wall has recesses. These recesses can be, in particular, elongated. In particular, the recesses penetrate completely through the side wall. For example, the first side wall section and the second side wall section can each be provided with one or more recesses. The recesses have the effect, in particular, of allowing the side wall to conform precisely to the battery.

[0013] The container preferably has a compartment for storing tools and a lid for opening and closing the compartment. The lid is secured by a snap-lock mechanism, allowing for easy opening and closing of the compartment without any tools. The compartment can be divided internally into different sections for various work tools and utensils, such as a section for screws and a section for bits. These sections can have slots into which, for example, different bits can be inserted, ensuring that all bits have a designated place within the compartment and are easily accessible.

[0014] The compartment can have a magnetic base inside, allowing magnetic tools, such as bits, to be held magnetically to the base. This results in a tidy interior for the compartment. Furthermore, the tools won't fall out when the compartment is opened. The magnetic base can cover the entire bottom of the compartment. However, it is also conceivable that the magnetic base is only present in a portion of the compartment's base.

[0015] The invention further relates to an arrangement comprising a battery for an electric hand tool and the container. As described above, this can in particular be a battery for a cordless screwdriver, a jigsaw, or a router, or a battery that can be used for various hand tools.

[0016] The battery can have at least one groove or shoulder for attaching the container. In particular, a rib of the container can engage in the groove or shoulder, meaning the groove or shoulder interacts with the rib of the container. This allows, for example, the container to be slid onto the battery, with the groove or shoulder acting as a guide for the rib during this process.

[0017] The invention further relates to a battery-powered hand tool, in particular a cordless screwdriver, a jigsaw or a router, with the previously described arrangement of a battery and a container.

[0018] The invention is explained below with reference to an embodiment shown schematically in the drawings. Fig. 1 a perspective view of an arrangement with a battery for an electric hand tool and a container, Fig. 2 another perspective view of the arrangement made ofFig. 1 , Fig. 3 a perspective view of the container made of Figs. 1 and 2 without battery and Fig. 4 another perspective view of the container made of Fig. 3 .

[0019] From the Figs. 1 and 2 An arrangement with a battery 50 and a container 10 is shown. The battery 50 is intended for use with a hand tool, for example, a cordless screwdriver, a jigsaw, or a router. It is also conceivable that the battery 50 can be used with different devices that have a standardized interface. For connection to the hand tool, the battery 50 has a connection section 52, which is equipped with various connection features to connect the battery 50 mechanically and electrically to the respective hand tool.

[0020] On two opposite sides, the battery 50 is provided with a recess 51, which will be discussed in more detail below. Instead of the recesses 51, it is also conceivable to provide a groove in the same location.

[0021] How Figs. 1 and 2 As shown, a container 10 is attached to the battery 50. The container 10 has a mounting section 11 and a compartment 17 that can be closed with a lid 16.

[0022] The fastening section 11 comprises a side wall, which in turn has side wall sections 13, 14, and 15. Side wall sections 13 and 14 are opposite each other and run approximately parallel to each other. The third side wall section 15 runs at right angles to side wall sections 13 and 14 and connects them.

[0023] To ensure that the side wall can fit precisely against the battery 50, the side wall sections 13, 14 are each provided with a recess 19, 20. The recesses 19, 20 penetrate completely through the respective side wall section 13, 14 and extend longitudinally and / or angularly along the respective side wall section 13, 14.

[0024] How especially Figs. 3 and 4 As can be clearly shown, the side wall sections 13, 14 each have a rib 12 at their free ends, which extends in the direction of the respective side wall section 13, 14 and projects laterally into a receiving space for the battery 50. The open receiving space is bounded by the side wall sections 13, 14, 15.

[0025] The mechanical, detachable fastening of the container 10 to the battery 50 is achieved by sliding the container 10 onto the battery 50, so that the ribs 12 are guided by the respective shoulders 51. In addition to the guiding function of the ribs 12 and the shoulders 51, a positive-locking connection between the container 10 and the battery 50 is also created when the container 10 is fully slid onto the battery and the ribs 12 rest on the shoulders 51.

[0026] Furthermore, in the present embodiment, the side wall is made of plastic. This allows the side wall to yield slightly when slid onto the battery 50, thus making the sliding possible. At the same time, due to the choice of material, the side wall can still exert sufficient pressure on the battery 50 to create a frictional connection between the container 10 and the battery 50 in addition to the positive-locking connection mentioned above.

[0027] The compartment 16 in the lower part of the container 10, mentioned earlier, is particularly suitable for storing tools such as bits, drill bits, countersinks, or saw blades. The lid 17 closes the compartment 16 and is secured by a snap-fit ​​connection. For this purpose, a snap hook 18 is provided on the lid 17, which is deflected elastically when the lid 17 is closed and then snaps into place on the container 10. The interior of the compartment 16 is divided into different sections for various work utensils and tools (not shown) and has a magnetic base to which the tools adhere magnetically.

[0028] The invention allows a relatively small and lightweight container with an organized interior to be easily attached to and removed from the battery without tools, and without negatively affecting the handling of the power tool. All tools are always readily available and do not need to be searched for when needed. Thus, the container 10 contributes to simplifying work with a battery-powered hand tool. Reference symbol list
