The support leg is provided with two support elements, whereby a vertical alignment of the nailer to the ground and thus a vertical driving the nails should be ensured in the ground. The pivot axis lies in the device plane and is parallel to the setting axis, so that the support elements in a first pivoting position of the support leg with the bolt guide element form a triangle for a three-point bearing of the nailer and are cut in a second pivoting position of the support foot of the device level. In both pivoting positions of the support leg protrudes in the direction of the setting axis of the other nail device. Another device is from the DE 2243414 known.

The object of the present invention is to provide a nail device with a support leg that offers improved accessibility to narrow areas for settlement.

This object is achieved with a nail device according to claim 1.

Preferably, the support leg is pivotable about at least 180 ° about the pivot axis. In this way, the support leg can in particular be swung out completely out of the region between the remaining nail device and the object, so that the nail device can also be used in less accessible areas in this pivoted-out pivot position of the support foot. Preferably, the pin guide element serves to guide the nails, bolts, pins or staples during setting or introduction into the object.

A preferred embodiment is characterized in that the support leg is provided with two support elements for a two-point bearing, so that the nail device has a three-point bearing together with the pin guide element. Preferably, the two support elements at a distance from the device level. The bolt guide element forms the first point bearing and the two support elements on the support foot form the two second and third point bearings for the nailer. At least for an object with a substantially planar surface, the bolt guide element and thus the setting axis can be aligned substantially perpendicular to the object plane by means of the three-point bearing. Preferably, the two support elements have the same distance from the pivot axis. In an alternative embodiment, the two support elements have different distances from the pivot axis. Preferably, the two support elements, in particular in the end region of the support elements, at least partially, in particular completely, made of an elastomer or rubber. The contact areas of the support elements then ensure a particularly secure hold of the nail device, in particular against slippage on the surface of the object.

A preferred embodiment is characterized in that the support leg is attached to the rest of the nail device with an overload mechanism, so that when a force is applied to the support leg which exceeds an overload force, the support leg is automatically detachable from the rest of the nail device. Preferably, the overload mechanism is formed by the pivoting mechanism. Preferably, the nail device further comprises a nail magazine, which connects the pin guide element with the support leg. A pivot bearing defining the pivot axis of the support leg is preferably arranged on the nail magazine. Particularly preferably, the pivot bearing is attached to the nail magazine.

Also preferably, the support leg is disposed at an end remote from the bolt guide element of the nail magazine.

Preferably, the nail device further comprises a scaffold hook, which is pivotable with the support leg about the pivot axis. Particularly preferably, the scaffold hook is firmly connected to the support leg.

The support foot preferably protrudes from the housing or optionally from the nail magazine. In preferred variants, the support leg protrudes from a fuel container receptacle, such as e.g. a gas can compartment, a battery holder or a handle or a handle extension.

Preferably, the two support elements, which form the two-point support on the support foot, at a distance of at least 1 cm, 3 cm, 5 cm or 10 cm to each other. This makes it difficult to tilt the nail device. In a further embodiment, the two support elements at a distance of at least 5 cm, 10 cm, 20 cm or 30 cm to the pin guide element.

Preferably, the support leg with a pivoting mechanism attached to the other nail device and stored and is fixed to the pivot mechanism in the first and second pivot position and detachable, in particular latched and unlatched, in particular by means of a movement of the support leg parallel to the pivot axis. When applying a force or movement on the support foot substantially parallel to the pivot axis of the support leg this can be attached to the other nail device in the two pivot positions and solved. This ensures a particularly simple fixation of the support leg in the two pivot positions. Preferably, the support leg is releasably attached to the other nail device and is brought by complete release of the remaining nail device from a first to a second pivot position.

In a further embodiment, the support leg is attached to the rest of the nailing device with an overload mechanism, such that when a force is applied to the support leg which exceeds an overload force, the support foot is automatically removed from the rest Nail device is releasable, in particular, the overload mechanism is formed by the pivot mechanism. In the practice of the nail device this can also fall, for example, and the support foot strikes the object. The overload mechanism ensures that when an overload force is exceeded with the overload mechanism, the connection between the support leg and the rest of the nail device is automatically and automatically released, thereby reducing the risk of damage to the support foot or the device.

In a further embodiment of the setting mechanism is electrically, pneumatically or combustion technology, the fuel is in particular solid, liquid or gaseous, operable. Particularly preferably, the nail device comprises a battery, for example in an electrically operated setting mechanism. Preferably, the nail device in a combustion-driven setting mechanism comprises a fuel cartridge, in particular in the form of a cartridge strip or a gas can.

In an additional embodiment, the housing of the nailer at least partially, preferably completely, made of metal and / or plastic. The support foot preferably comprises as the material plastic, which is particularly preferably fiber-reinforced.

In the Fig. 1 to 4 a nailer 1 is shown, which serves nails 11 in an object or background, not shown, for. B. of wood, concrete or steel, collect. The nail device 1 has for this purpose a housing 2 made of metal and / or plastic, which is generally in several parts. In this case, is within the housing 2, a setting mechanism, not shown, which is electrically operated by a battery 3, respectively. A part of the housing 2 forms a nail magazine 5. The nail magazine 5 comprises a large number of nails 11 and for setting the nails, the nails are transported from the nail magazine 5 to the setting mechanism and by means of the activated by a trigger 7 setting mechanism by a pin guide element 6 as Part of the setting mechanism driven into the object. The bolt guide element 6 in this case has a longitudinal axis which forms a setting axis 12 of the nail device 1. To hold the nail device 1, the housing 2 is designed such that it also comprises a handle 4 for holding the nail device 1. The outermost end of the pin guide element 6 forms a first contact point on the object. The bolt guide element serves to guide the nails 11 during setting or introduction into the object.

The nail device has a support leg 8 with a first support element 9 and a second support element 10 for resting on the object, wherein the first support element 9 and the second support element 10 together form a second support point 14. A connecting line between the first support point 13 and the second support point 14 and the setting axis 12 span a device level of the nail device. The support leg 8 is designed to be pivotable and has for this purpose a pivot bearing 16, which defines a pivot axis 15 which is oriented perpendicular to the plane of the device. The support leg 8 is pivotable about a little more than 180 ° about the pivot axis 15. This allows the support leg 8 from the Area between the other nailer 1 and the object are completely swung out, so that the nailer can also be used in less accessible areas. The pivot bearing 16 and the support leg 8 are arranged at an end remote from the bolt guide element 6 of the nail magazine 5. The support leg 8 is fixed by means of a snap connection to the pivot bearing 16, so that upon application of a force on the support leg 8, which exceeds an overload force, the support leg 8 automatically releases from the pivot bearing 16. The swivel mechanism works as an overload protection for the support leg. 8
