DETAILED DESCRIPTION

(11) FIG. 1 shows views of various support structures (10) as they are known from the prior art. The support structures (10) can be connected to hand-held power tools (2), although scarcely any technically satisfactory solutions have been known previously to ensure a stable, secure and robust connection between the support structure (10) and the hand-held power tool (2). Such a technical solution, which is also easy to use, allows the position of the hand-held power tool (2) to be adapted in relation to the support structure (10) to the center of gravity of the hand-held power tool (2) and universally, i.e. can be used for a particularly large number of different hand-held power tools (2) or types of hand-held power tools (2), is provided with the present invention. This invention is illustrated in FIGS. 2 to 5.

(12) FIGS. 2 to 5 show a first refinement of the invention, in which a counter structure (11) is designed as a receiving region and is present in the rear region (17) of the interface (1). In particular, FIG. 2 shows a side view of an exemplary hand-held power tool (2) which is connected to a preferred embodiment of the interface (1) (connected state). The hand-held power tool (2) can be a battery-operated device or a device with a mains connection. In the exemplary embodiment of the invention shown in FIG. 2, the interface (1) is located on an upper side of the hand-held power tool (2). The hand-held power tool (2) has a housing (3), a first handle (4) and a second handle (5), wherein the first handle (4) is located in a front region (8) of the hand-held power tool (2) and is fastened with a tightening strap (6) to the hand-held power tool (2). In particular, the tightening strap (6) can be arranged circumferentially around the front region (8) of the hand-held power tool (2), with it usually being braced fixedly or tightly. The first fastening means (7) of the interface (1) can be pushed between the tightening strap (6) and the hand-held power tool (2). The first fastening means (7) can in particular be designed as a hook, such that a flat underside of the first fastening means (7) rests on a preferably flat section of the upper side of the hand-held power tool (2). This produces a connection between the first fastening means (7) of the interface (1) and the hand-held power tool (2).

(13) The adjustment means (13a), which can be designed as a knurled screw, is also located in the front region (16) of the interface (1). With said adjustment means/knurled screw, a distance between the first fastening means (7) and a receiving region of the interface (1) can be changed, wherein the receiving region can represent a counter structure (11) within the meaning of the invention. The receiving region is preferably located in a rear region (17) of the interface (1). If the interface (1) is to be connected to a hand-held power tool (2), the distance between the first fastening means (7) and the receiving region can be shortened with the adjustment means (13a) such that the hand-held power tool (2) is jammed or clamped in the interface (1). The receiving region of the interface (1) can, for example, be at least partially hollow or can have a cavity, wherein the receiving region in this cavity can receive part of the power tool (2) or of the housing (3) of the hand-held power tool (2). By receiving part of the hand-held power tool (2) in the receiving region or a cavity in the receiving region, a particularly stable, mechanical connection between the interface (1) and the hand-held power tool (2) can be made possible.

(14) The second handle (5) of the hand-held power tool (2) is preferably located in a rear region (12) of the hand-held power tool (2). On an upper side of the interface (1) there is a grid (14) by means of which the second fastening means (9) of the interface (1) can be displaced along a central axis (15) of the interface (1). Due to the movable configuration of the second fastening means (9), the position thereof can be adapted to a center of gravity of the hand-held power tool (2). This function is particularly advantageous when the center of gravity of a hand-held power tool (2) changes, for example, when the tool, such as a drill, chisel or drill bit, of the hand-held power tool (2) is changed.

(15) FIG. 3 shows an oblique front view of an exemplary hand-held power tool (2) which is connected to the first preferred embodiment of the interface (1). In particular, the contact regions (18, 19) are shown in FIG. 3. In the embodiment of the invention shown in FIG. 3, the first contact region (18) is in the region of the tightening strap (6) of the hand-held power tool (2) or of the first fastening means (7) of the interface (1), while the second contact region (19) is in the region of the basic structure (11) that is designed as a receiving region. In the contact regions (18, 19) there is preferably in each case contact between the interface (1) and the hand-held power tool (2), i. e. in these regions (18, 19) the interface (1) and the hand-held power tool (2) are in contact with each other. The first contact region (18) is preferably formed by the first fastening means (7), which is preferably designed as a hook, and the tightening strap (6) or the hand-held power tool (2), while the second contact region (19) is formed by the receiving region and the rear region (12) of the housing of the hand-held power tool (2).

(16) FIG. 4 shows a side view of the first preferred embodiment of the interface (1), wherein the interface (1) is not connected to a hand-held power tool (2) in the view shown in FIG. 4 (disconnected state). The left half of the image shows the front region (16) of the interface (1) and the right half of the image shows the rear region (17) of the interface (1). The adjustment means (13a) and the first fastening means (7) are located in the front region (16) of the interface (1). In a particularly preferred exemplary embodiment of the invention, these can be formed by a knurled screw (13) and a hook (7). The hook (7) is designed to enter into engagement with a tightening strap (6) of the hand-held power tool (2). The hook (7) in particular forms a first contact region (18) with the hand-held power tool (2). The adjustment means (13a) can be used to adjust a distance between the first fastening means (7) and the receiving region of the interface (1), the receiving region being located in the rear region (17) of the interface (1). In the first preferred refinement of the invention, the receiving region forms the counter structure (11) and is preferably designed to receive part of the hand-held power tool (2) or to produce a connection between the interface (1) and the rear region (12) of the hand-held power tool (2). The receiving region can preferably also be referred to as a handle receptacle.

(17) In the upper region of the interface (1) there is a grid (14) which enables the second fastening means (9) to move axially along a central axis (15) of the interface (1). The central axis (15) preferably runs substantially parallel to the grid (14) of the interface (1). Owing to the movable configuration of the second fastening means (9), which can in particular be designed as a retaining eyelet, the position of the second fastening means (9) can be adapted to the center of gravity of the hand-held power tool (2). The second fastening means (9) is provided in particular to connect the hand-held power tool (2) to a support structure (10) (see e.g., FIG. 1).

(18) FIG. 5 shows a plan view of the first preferred embodiment of the interface (1). In the plan view of the interface (1) shown in FIG. 5, in particular the position and the course of the central axis (15) of the interface (1) can be clearly seen.

(19) FIGS. 6 to 8 show a second refinement of the invention, in which a counter structure (11) is designed as a retaining ring and is present in the front region (16) of the interface (1). The retaining ring can be placed around the device neck of a hand-held power tool (2) and adapted to the size or the circumference of the hand-held power tool neck using an adjustment means (13b). The first fastening means (7), which is preferably designed as a hook, forms a first contact region (18) and is in spatial proximity to the counter structure (11) which is designed as a retaining ring.

(20) FIG. 7 shows an oblique front view of the second preferred refinement of the interface (1). The counter structure (11), which forms the second contact region (19) with the hand-held power tool (2, not shown), is arranged in the front region (16) of the interface (1). The contact is formed in particular by placing the retaining ring around the neck of the hand-held power tool (2). The retaining ring has a slot in its upper region, wherein the size of said slot-shaped opening can be adjusted. This is preferably done with the adjustment means (13b), which can in particular be designed as a knurled screw. It is preferred in the context of the invention that the adjustment means (13b) is designed to adjust a diameter of the basic structure (11) designed as a retaining ring, as a result of which the basic structure (11) or the device (1) can be adapted particularly flexibly to different hand-held power tools (2) or to the dimensions thereof.

(21) The two contact regions (18, 19) are preferably used to provide the system comprising the hand-held power tool (2) and the interface (1) with stability. In particular, the provision of two contact regions (18, 19) enables the hand-held power tool (2) to be suspended in the device (1) with little vibration. The retaining ring of the basic structure (11) advantageously encloses the neck of the hand-held power tool (2) such that a particularly stable connection between the hand-held power tool (2) and the device (1) can be achieved in this way.

(22) FIG. 8 shows a side view of the second preferred refinement of the interface (1). The first fastening means (7) and the basic structure (11) can be clearly seen in the front region (16) of the interface (1), wherein the first fastening means (7), which is preferably designed as a hook, forms a first contact region (18) between the hand-held power tool (2) and the device (1), while the basic structure (11), which is preferably designed as a retaining ring, forms a second contact region (19) between the hand-held power tool (2) and the device (1).
