Definitions

  • the invention relates to a pneumatic nailer with a working piston, which is connected to a driving ram for driving a fastener and is applied to trigger a Eintreibvorgangs with compressed air, a triggering device having a manually actuable trigger and a touch sensor, wherein a joint actuation of trigger and embarksetzr a controls a first control valve and triggers a driving operation, if the pressure in a safety control chamber is above a predetermined pressure threshold, and a second control valve, which is actuated upon actuation of the trigger independently of an actuation of the Aufsetzrylers.
  • the Aufsetztler is a mechanical component, which is usually held by a spring in a protruding over a neck tool of Druck Kunststoffnaglers position. If the compressed air bearing is attached to a workpiece, the touch sensor is displaced against the force of the spring until the muzzle tool rests against the workpiece or almost rests. Only with such actuated Aufsetzitchler a driving operation can be triggered. As a result, the known compressed air nailers offer a significantly improved security against unintentional release compared to devices without Aufsetzthler.
  • Pneumatic nailer with a triggering device of the type described can be used in two different modes.
  • the pneumatic nailer is first attached to a workpiece and thereby actuated the landing sensor. Subsequently, the trigger is actuated by hand, thereby triggering a single drive.
  • the user In the so-called contact release, also referred to as touch, the user already holds the trigger while pressing the pneumatic nailer against the workpiece.
  • the trigger When attaching to the workpiece of the touch sensor is actuated and thereby initiates a drive-in process.
  • the compressed air nailer can be repeatedly set in rapid succession, which allows a very fast working, especially if many fasteners must be driven for a sufficient attachment to the positioning accuracy only small demands are made.
  • the contact triggering procedure entails an increased risk of injury. For example, not only does the user depress the hand-operated trigger when he wants to place the pneumatic nailer on one and the same workpiece a few centimeters from the last driven fastener, but also when changing to another remotely located workpiece in an accidental contact of an object or body part with the Aufsetzrler a driving operation are triggered. For example, accidents can occur when a user (in disregard of important safety regulations) climbs a ladder with the pneumatic nailer while holding the trigger and accidentally brushing his leg with the touch probe.
  • the pneumatic rodger is used to drive fasteners such as nails, pins or staples.
  • the pneumatic nailer can have a magazine for the fastening means, from which in each case a fastening means is supplied to a receptacle of a necking tool of the pneumatic nailer.
  • venting is always meant that a connection to a non-pressurized space, in particular to the outside air, is produced.
  • ventilation is always meant that a connection is made to a compressed air leading room.
  • a working piston of the pneumatic nailer When initiating a driving operation, a working piston of the pneumatic nailer is pressurized with compressed air.
  • the working piston drives a Eintreibst Schemeel, which is connected to the working piston.
  • the drive ram strikes a rear end of the fastener in the receptacle of the muzzle tool and drives the fastener into the workpiece.
  • the triggering device has a hand-operated trigger, for example in the form of a tilt or push button, and a touch sensor.
  • the touch sensor may be a mechanical component that projects beyond the front end of the muzzle tool and is held in this position by a spring until the pneumatic nailer is attached to a workpiece. Then the Aufsetzterler is displaced against the direction of the spring force and against the driving direction. If this actuation of the touch probe together with an actuation of the trigger, a first control valve is actuated, whereby a driving operation can be triggered.
  • the first control valve With a common actuation of trigger and Aufsetzr the first control valve is activated. If only one of the manually actuable release and the touch sensor is actuated, the first control valve will not be actuated. For a joint actuation of trigger and embarksetzr it is sufficient if both the trigger and the touch sensor at a certain time both at the same time in the actuated state. This can be achieved on the one hand by a simultaneous operation, but also in any order. For example can, as is typical for a single triggering, first the touch sensor be actuated and then the hand-actuated trigger. In contact tripping operation, however, the hand-actuated trigger and then the touch sensor can be operated first.
  • the control of the first control valve can be achieved by a mechanical coupling of the manually operated release and the Aufsetzterlers.
  • a control pin of the first control valve can only be displaced when the trigger and the touch sensor are actuated together, and the first control valve can thereby be activated.
  • the actuation of the first control valve triggers a drive-in operation if the pressure in the safety control chamber is above a predetermined pressure threshold. Otherwise, when driving the first control valve no drive-in process is triggered.
  • the second control valve is actuated upon actuation of the manually operable trigger independently of an actuation of the Aufsetzterlers.
  • the second control valve is thus activated with each actuation of the trigger.
  • a control pin of the second control valve may be arranged so that it is displaced from its rest position with each actuation of the trigger.
  • the safety control chamber is vented independently of the position of the second control valve continuously via a throttle and separated when controlling the second control valve of a pressurized housing interior.
  • the safety control chamber In an initial state of the pneumatic nailer, the safety control chamber is connected to the pressurized housing interior.
  • initial state is always meant a state in which the pneumatic nailer is connected to a compressed air supply and neither the touch sensor nor the trigger are actuated.
  • the safety control chamber becomes continuous vented via the throttle.
  • the air flow escaping through the throttle is no longer compensated by flowing from the housing interior into the safety control chamber air and the pressure in the safety control chamber falls within a certain time the predetermined pressure threshold, so that further triggering is no longer possible.
  • the throttle or a line connecting the throttle with the outside air can be arranged in particular and a flow of air which escapes via the throttle can be dimensioned so that the air escaping via the throttle causes a perceptible operating noise for a user.
  • This operating noise indicates the correct functioning of the safety device and the ready-to-fire status of the device: If a malfunction occurs, for example if the throttle is soiled, the operating noise will change or become dull. If the operating sound is silenced when the trigger is depressed as a result of the pressure loss in the safety control chamber, this indicates to a user that further drive-in operations can not be triggered until the pressure in the safety control chamber has been restored by releasing the trigger.
  • the safety control chamber is vented when the trigger is not actuated via the second control valve.
  • a direct connection between the safety control chamber and a housing interior under pressure is produced via the second control valve, which leads to an instantaneous ventilation of the safety control chamber.
  • the pneumatic nailer is located Therefore, after releasing the trigger within a very short time again in a ready shot initial state.
  • the throttle is connected to a line which connects the second control valve with the safety control chamber.
  • the throttle may be in any connection between the safety control chamber and outside air.
  • the arrangement of the provided for the ventilation of the safety control chamber via the second control valve line allows a particularly simple, compact design.
  • the first control valve, the second control valve and the throttle are combined in a valve block. This measure also serves a simple and compact construction.
  • the pressure in the safety control chamber acts on a safety valve piston of a safety valve which shuts off a line which is vented or vented when the first control valve is actuated.
  • the safety control chamber can be connected via a line with a working volume of the safety valve or it can form this working volume.
  • the pressure in the safety control chamber can in particular press the safety valve piston in one direction, which corresponds to an open position of the safety valve.
  • a spring biases the safety valve piston against the pressure in the safety control chamber.
  • the position of the safety valve therefore results from the interaction of the spring force and the pressure exerted by the pressure in the safety control chamber on the safety valve piston force. It can therefore be adjusted by tuning the spring to the effective cross section of the safety valve piston exactly specify up to what pressure in the safety control chamber the safety valve remains in its open position.
  • the pneumatic nailer has a pilot valve with a control piston, wherein the control piston and the safety valve piston are arranged along a common longitudinal axis.
  • the pilot valve is used to control a main valve of the pneumatic nailer, via which the working piston is ventilated. Said arrangement of control piston and safety valve piston allows a particularly easy to manufacture, compact design of the pneumatic nailer.
  • control piston and the safety valve piston are arranged laterally of the working cylinder.
  • common axis of the control piston and safety valve piston can be aligned parallel to a longitudinal axis of the working cylinder.
  • an opening cross-section of the throttle is dimensioned such that during operation of the pneumatic nailer with a designated operating pressure of the pressure in the safety control chamber falls below the predetermined pressure threshold in a period of 0.1 s to 10 s after activation of the second control valve.
  • the pressure threshold can be exceeded in a period between 1 s and 5 s after activation of the second control valve, for example after approximately 4 s.
  • the opening cross-section of the throttle can be adjustable, so that the period can be individually regulated. Preferably, this regulation takes place only once by the manufacturer of the pneumatic nailer and can only be changed by impermissible manipulation by a user. In any case, the pneumatic nailer is locked in time to prevent in many typical application situations a driving operation as a result of unintentional actuation of the Aufsetznchlers.
  • the pneumatic nailer on a check valve via which the safety control chamber is vented when triggering a Eintreibvorgangs.
  • the initial state is restored upon initiation of a driving operation with respect to the pressure in the safety control chamber. This can happen very fast. If, after the drive-in operation, the trigger is still kept pressed, the pressure in the safety control chamber approaches in the previously described manner again the pressure threshold, which is undershot after the predetermined period of time. Until then, a further release by pressing the Aufsetztlers is possible at any time, so that the Druck Kunststoffnagler is suitable without restriction for fast successive Eintreibvor réellen in the contact triggering process.
  • the pneumatic nailer 10 has a handle 12 which is fixed to a lower housing part 140, which is closed at the top by a housing cap 142.
  • the manually operable trigger 14 is pivotally mounted about a pivot axis 16 on the housing of the pneumatic nailer 10 and arranged so that it can be easily operated by a user who holds the pneumatic nailer 10 on the handle 12 with the index finger.
  • a button 18 located at the top of the trigger 14 engages a switching pin 20 of a second control valve 22, displaces the switching pin 20 upwardly and thereby controls the second control valve 22. Since this activation of the second control valve 22 is effected directly by the button 18 fixedly arranged on the trigger 14, it takes place independently of the actuation of a touch sensor 24.
  • the Aufsetztler 24 is about the mouth 26 of a muzzle tool 28 by a few millimeters down over. If the pneumatic nailer 10 is attached to a workpiece, the Aufsetzmeler 24 is displaced upward against the force of a spring, not shown, until it is flush with the mouth 26 or only slightly beyond the mouth 26.
  • the touch sensor 24 is mechanically coupled to a power transmission element 30, which moves with the movement of the Aufsetzmelers 24 upwards.
  • the power transmission element 30 is movably guided on the housing of the pneumatic nailer 10 and for this purpose has a slot 32, through which a guide pin 98 is passed.

  • the lever 36 is then disposed approximately parallel to a longitudinal direction of the trigger 14 and its upper surface acts as a button 40 which, upon joint actuation of the touch sensor 24 and the trigger 14, displaces a switching pin 42 of a first control valve 44 upwardly and thus drives the first control valve 44 ,
  • the mouth tool 28 has a receptacle 46, to which a fastening means is supplied from a magazine 48 in each case.
