Description

Prior ArtThe present invention relates to a driving device, in particular a nail gun, having a housing in which a driving unit for driving in, in particular shooting in, driving means is arranged, wherein a linearly displaceable working contact element is assigned to the driving unit, and wherein the housing has a handle on which an actuatable operating element for actuating the driving unit is arranged.DE 10 2010 062 368 A1 discloses a driving-in device designed as a nail gun. This nail gun has a housing in which a driving unit for driving in, in particular shooting in, driving means, in particular nails, is arranged. The housing has a handle on which a manually actuatable switch for actuating the driving-in unit is arranged. Furthermore, a linearly displaceable working contact element is assigned to the driving-in unit.Usually, such a nail gun is secured by redundant actuation of the manually actuatable switch and the linearly displaceable working contact element. In a so-called sequential mode ("sequential mode"), the linearly displaceable contact element is first actuated by pressing against a workpiece in each driving-in process and the manually actuatable switch is subsequently pressed. In a so-called bump fire mode ("bump fire mode"), the manually actuatable switch is first pressed and the linearly displaceable contact element is subsequently actuated by pressing against a workpiece. In this impact fire mode, the manually actuatable switch generally remains pressed during successive driving-in processes, so that a subsequent actuation of the driving-in unit takes place in each case by pressing the linearly displaceable working contact element against a workpiece.Disclosure of the InventionThe invention relates to a driving device, in particular a nail gun, having a housing in which a driving unit for driving in, in particular shooting in, driving means is arranged, wherein a linearly displaceable working contact element is assigned to the driving unit. The housing has a handle on which an actuatable operating element for actuating the driving-in unit is arranged. At least one actuatable safety element is assigned to the driving unit, wherein a linear displacement of the working contact element and an actuation of the operating element and the at least one safety element are required for triggering the driving unit.The invention thus makes it possible to provide a driving device in which a secure and reliable protection of a user of the driving device can be ensured by the at least one safety element by the required actuation of at least three different actuating elements, i.e. the normally open element, the operating element and the at least one safety element.Preferably, a control unit is provided which is designed to trigger the driving-in unit as a function of a respectively determined actuation pattern of the normally open contact element, operating element and at least one safety element.Thus, different operating modes can be realized in a simple manner depending on a respectively determined actuation pattern.In the case of a first actuation pattern, the control unit preferably triggers the driving-in unit if, after actuation of the at least one safety element and of the operating element, a linear displacement of the normally open contact element takes place.This makes it possible to realize the so-called bump fire mode ("bump fire mode") of the driving apparatus.In the case of a second actuation pattern, the control unit preferably triggers the driving-in unit when, after actuation of the at least one safety element and a linear displacement of the normally open contact element, actuation of the operating element takes place.This makes it possible to realize the so-called sequential mode ("sequential mode") of the driving-in device.The actuatable operating element is preferably designed as a manually actuatable main switch.A robust and reliable actuatable operating element can thus be provided.The at least one actuatable safety element preferably has at least one manually actuatable safety switch.Thus, an uncomplicated and cost-effective actuatable safety element can be provided.According to one embodiment, the at least one actuatable safety element and the actuatable operating element are arranged at least partially on diametrically opposite sides of the handle.Thus, a one-handed actuation of the at least one actuatable safety element and of the actuatable operating element can be made possible in a simple manner, for example by an actuation of the actuatable safety element with the palm of the hand and an actuation of the actuatable operating element with the index finger of a hand.According to one embodiment, the at least one actuatable safety element and the actuatable operating element are arranged at least partially on the same side of the handle.Thus, a one-handed actuation of the at least one actuatable safety element and of the actuatable operating element can likewise be made possible in a simple manner, for example by an actuation of the actuatable safety element with the middle finger and an actuation of the actuatable operating element with the index finger of a hand.According to one embodiment, the at least one actuatable safety element is arranged on a lateral housing wall of the housing.Thus, in turn, a one-handed actuation of the at least one actuatable safety element and of the actuatable operating element can be made possible in a simple manner, for example by an actuation of the actuatable safety element with the thumb and an actuation of the actuatable operating element with the index finger of a hand.Preferably, a driving-in means magazine is fastened to the housing, which magazine is designed to receive a plurality of driving-in means.Thus, a plurality of driving means can be easily provided.Brief Description of the DrawingsThe invention is explained in more detail in the following description with reference to exemplary embodiments shown in the drawings. The following are shown: FIG. 1 is a perspective view of a driving device designed as a nail gun, having a housing, a handle and a working contact element, and FIG. 2 is a side view of a detail II of the housing and of the handle of FIG. 1.DESCRIPTION OF THE EMBODIMENTSIn the figures, elements having the same or comparable function are provided with identical reference numerals and are described in more detail only once.FIG. 1 shows an exemplary driving device 100 having a housing 102, in which a driving unit 112 for driving in, in particular shooting in, driving means is arranged. Illustratively, a linearly displaceable working contact element (AKE) 120 is assigned to the driving-in unit 112.According to one embodiment, the driving-in device 100 is designed as a nail gun. Here, the driving-in device 100 preferably has a driving-in agent magazine 104. The propellant magazine 104 is illustratively mounted to the housing 102 and serves to receive and provide a plurality of propellants for use. The driving agent magazine 104 may be configured to receive two or more different types of driving agents, e.g., nails-type driving agents having nail heads and / or nails-type driving agents having double heads, etc.Illustratively, the propellant magazine 104 is connected to a nose assembly 114 of the propellant 100. The nose assembly 114 has at least the AKE 120, which is assigned to the driving unit 112 and via which the driving unit 112 can drive driving means, in particular driving means, from the driving means magazine 104 into a corresponding workpiece at an assigned driving depth. The assigned driving depth can be predefinable or adjustable via a suitable driving depth setting device.The AKE 120 preferably has a wire structure 124 which forms a blunt contact tip 122, which serves to contact a corresponding workpiece when the driving-in device 100 is used. The wire structure 124 and thus the AKE 120 as such is arranged on the housing 102 so as to be longitudinally displaceable, i.e. displaceable in a direction indicated by an arrow 129 relative to the housing 102.The housing 102 illustratively includes a handle 106. The handle 106 is designed, for example, for holding the driving device 100 with one hand.Preferably, an actuatable operating element 108 for actuating the driving-in unit 112 is arranged on the handle 106. The actuatable operating element 108 is illustratively designed as a manually actuatable main switch.The handle 106 preferably has a foot region 110, which is formed on a region of the handle 106 facing away from the driving-in unit 112. A battery pack 190 for supplying power to the driving device 100 independently of the grid is arranged on the foot region 110 by way of example. Alternatively, the driving device 100 can be supplied with power via a power cable depending on the grid, or can be operated with compressed air, for example independently of the current via a compressor.According to the invention, the driving-in device 100 has at least one actuatable safety element ( 210, 220, 230 in FIG. 2 ), which is assigned to the driving-in unit 112 and is shown only in FIG. 2 for the sake of simplicity and clarity. For triggering the driving-in unit 112, linear displacement of the AKE 120 and actuation of the actuatable operating element 108 and of the at least one safety element ( 210, 220, 230 in FIG. 2 ) are required. In this case, for example, first of all an actuation of the at least one safety element ( 210, 220, 230 in FIG. 2 ) may always be necessary before a linear displacement of the AKE 120 or an actuation of the actuatable operating element 108 takes place or may take place.The driving-in unit 112 is preferably triggered accordingly by a control unit 180 which is preferably arranged in the housing 102 and is designed to trigger the driving-in unit 112 as a function of a respectively determined actuation pattern of the AKE 120, operating element 108 and at least one safety element ( 210, 220, 230 in FIG. 2 ). In a first exemplary actuation pattern, the control unit 180 can trigger the driving-in unit 112 if a linear displacement of the AKE 120 takes place after actuation of the at least one safety element ( 210, 220, 230 in FIG. 2 ) and of the operating element 108. This corresponds to an implementation of a so-called bump fire mode ("bump fire mode") of the driving device 100.In a second exemplary actuation pattern, the control unit 180 can trigger the driving-in unit 112 if, after actuation of the at least one safety element ( 210, 220, 230 in FIG. 2 ) and a linear displacement of the AKE 120, actuation of the operating element 108 takes place. This corresponds to an implementation of a so-called sequential mode ("sequential mode") of the driving-in device 100.The at least one safety element (210, 220, 230 in FIG. 2 ) is preferably arranged on the handle 106 or on the housing 102, in particular in a region marked II. Exemplary arrangement variants are shown in FIG. 2 and described below.FIG. 2 shows the region of the driving device 100 identified by II in FIG. 1, which illustratively comprises a section of the housing 102 and of the handle 106 of the driving device 100, in which the housing 102 merges, by way of example, into the handle 106. The actuatable operating element 108 is arranged on the handle 106, which is illustratively designed as a manually actuatable main switch.As described with reference to FIG. 1, at least one actuatable safety element is provided according to the invention. The at least one actuatable safety element preferably has at least one manually actuatable safety switch.By way of example, two actuatable safety elements 210, 220 are arranged on the handle 106, and one actuatable safety element 230 is arranged on the housing 102. At this point, it should be pointed out that it is sufficient from a safety standpoint to realize or provide only one of the three actuatable safety elements 210, 220, 230. Accordingly, the driving-in device 100 of FIG. 1 can be configured either only with the actuatable safety element 210, only with the actuatable safety element 220, or only with the actuatable safety element 230. Alternatively, any combinations of the three actuatable safety elements 210, 220, 230 can also be realized or provided. For example, the driving-in device 100 of FIG. 1 can be configured with the actuatable safety elements 210 and 220, the actuatable safety elements 210 and 230, or the actuatable safety elements 220 and 230.The actuatable safety element 210 and the actuatable operating element 108 are preferably arranged at least partially on diametrically opposite sides of the handle 106. In this case, the actuatable safety element 210 is illustratively arranged on a rear side 212 of the handle 106 and the actuatable operating element 108 is arranged on a front side 222 of the handle 106. Thus, in particular, a one-handed actuation of the actuatable safety element 210 and the actuatable operating element 108 can be made possible, e.g. by an actuation of the actuatable safety element 210 with the palm of a hand and an actuation of the actuatable operating element 108 with the index finger of the same hand.The actuatable safety element 220 and the actuatable operating element 108 are preferably arranged at least partially on the same side of the handle 106. In this case, the actuatable safety element 220 and the actuatable operating element 108 are illustratively arranged on the front side 222 of the handle 106. Thus, in particular, a one-handed actuation of the actuatable safety element 220 and of the actuatable operating element 108 can be made possible, for example by an actuation of the actuatable safety element 220 with the middle finger of one hand and an actuation of the actuatable operating element 108 with the index finger of the same hand.The actuatable safety element 230 is preferably arranged on a lateral housing wall 232 of the housing 102. Thus, in particular, a one-handed actuation of the actuatable safety element 230 and of the actuatable operating element 108 can be made possible, for example by an actuation of the actuatable safety element 230 with the thumb of one hand and an actuation of the actuatable operating element 108 with the index finger of the same hand.It should be pointed out at this point that the respective arrangement of the actuatable safety elements 210, 220, 230 on the handle 106 or on the housing 102 is merely exemplary in nature and should not be understood as limiting the invention. Rather, another arrangement can also be realized, e.g. an arrangement of the safety element 230 on a side surface of the handle 106, or a downwardly offset, i.e. deeper, arrangement of the safety element 220 on the front side 222 of the handle 106, so that its actuation takes place e.g. with the little finger of a hand, etc. Moreover, it is also possible e.g. to arrange the safety element 230 on the housing 102 in the region of the nose assembly 114 of FIG. 1 or to arrange the safety element 210, 220 on an upper side of the housing 102 in FIG. 1, etc.References included in the specificationThis list of documents cited by the applicant has been produced in an automated manner and is only included for the better information of the reader.
