Definitions

  • the invention relates to a magazine for a power-driven driving tool for receiving pins or nails, in particular headless pins or nails according to the preamble of patent claim 1.
  • the driving plunger which drives the fastener into a workpiece, is actuated with spring force, electrically or pneumatically.
  • the fastening means for example staples, nails or pins
  • the magazines are mostly elongated bodies which have a guide channel on the inside which is roughly adapted to the profile of the fastening means.
  • a correspondingly narrow guide channel is provided, along which they are moved by the feeder. If possible, the nails or pencils are not only guided from below, but also from above. With nails or pens of different lengths, however, a corresponding change in the height of the guide is required, which can be achieved by appropriate manipulation of the magazine.
  • a magazine has become known in which a rail forming the top wall of the guide channel is arranged to be adjustable in height.
  • a rod which can be actuated by means of a button and which can be locked in different height positions is connected to the rail and must be adjusted for a different nail or pin length.
  • the actuation button protrudes relatively far up from the top of the magazine and can impair the handling of the driving tool.
  • a magazine which is also suitable for receiving headless pens or nails.
  • the top wall of the guide channel can have a different height than the bottom wall in order to adapt to the lengths of the pins or nails.
  • a side wall of the guide channel is formed by a longitudinal surface of at least one lamella, which is mounted in the upper region of the guide channel along an axis transverse to the longitudinal axis of the guide channel and is preloaded by means of a spring in the direction of the other side wall.
  • the cover rail is guided on the magazine by means of a rail guide and, in a retracted position, releases the guide channel for loading from the side. In the closed front position of the cover rail, the longitudinal surface of the slat either lies against the other side wall or is at a short distance from it or at the upper ends of the nails or pins.
  • the invention is therefore based on the object of providing a magazine for a power-driven driving tool which can be loaded easily and yet can accommodate headless pins, nails or the like of different lengths without the magazine having to be manipulated.
  • the cover rail is guided in such a way that it makes a transverse movement when being adjusted from the closed to the open position or in the opposite direction.
  • the fins In the open (and partially open) position, therefore, the fins have a distance from the opposite side wall that is greater than the diameter of the shaft and head of the pins or nails.
  • the pins or nails can therefore be easily inserted into the guide channel.
  • the transverse movement of the cover rail that occurs shortly before the closed position is used to position the spring-loaded slats according to the pin length to be processed for height limitation.
  • the spring-loaded lamellae lie in the area of the inserted pin length against the shafts of the pins and in the area above the length of the pin against the opposite side wall.
  • the cover rail is expediently held by an elongate support part connected to the driving tool.
  • the lamella can be mounted in the supporting part or in the cover rail.
  • the arrangement of the slats in the cover rail is preferable.
  • the lamella is mounted in a guide in the cover rail.
  • the guide has a guide recess open to the guide channel, the upper guide wall against the other wall of the guide approx.
  • the slats are limitedly movable so that their wall surface facing the guide channel is flush with the upper guide surface when the cover rail is in its fully or partially open position.
  • the lamella has limited lateral mobility.
  • a simple guide can consist in the fact that two spaced elongated holes are formed in the lamella, through which pins pass.
  • the slats can be formed from metal or plastic.
  • the spring acting on the slats is, for example, a leaf or bar spring. In the case of metal slats, the leaf spring is a separate component that is fastened to the slat using suitable fastening means. If, on the other hand, the lamella is molded from plastic, the leaf spring can be molded in one piece.
  • the cover rail is approximately C-shaped in cross section. Their free edges slide in the upper and lower grooves of a carrier component. So that the above-described lateral movement of the C-shaped cover rail can be achieved, the grooves are provided over their greater length with a width which is greater than the thickness of the edges of the cover rail which engage in the grooves. However, the grooves have a laterally offset section near the firing channel. Furthermore, the front and rear ends of the free edges of the cover rail have thickened sections, the thickness of which corresponds approximately to the width of the grooves. The thickened sections ensure that the cover rail is axially guided laterally in the carrier component.
  • the front thickened sections therefore ensure that the lamella is at the distance described above from the other wall.
  • the front thickened sections migrate into the offset groove section and the rear thickened sections enter the guide grooves, so that the described lateral offset of the cover rail thereby occurs and the lamella approaches the whole of the opposite guide channel wall. If, on the other hand, there is a nail in the area of a lamella, the lamella rests resiliently against the nail.
  • the lower guide for the nails or pins is preferably formed by a lateral extension of the carrier component.
  • a guide bar for the reversely U-shaped pusher can also be attached to this lateral approach.
  • one embodiment of the invention provides that the carrier component is guided at the front end by means of a relatively short guide part attached to the muzzle tool and can be fastened to the muzzle tool with a screw.
  • the carrier component is also fastened in the rear component by means of a further screw which is passed through an elongated hole in the carrier component. If the two screws mentioned are loosened, the carrier component can be pulled back a short distance and thus free the upper area of the drive channel.
  • the magazine according to the invention can be used for nails or pens with or without a head.
  • the wall section opposite the lamella preferably has a depression which extends over the length of the guide channel.
  • Fig. 1 shows a compressed air-powered driving tool 15, which has an upper handle part 16, a drive part 17 and a magazine 18.
  • the elongated magazine 18 extends between a mouth tool 19 and a holding part 20 which is connected to the rear end of the handle part 16. 2 that a cover rail 21 of the magazine 18 is partially pushed back.
  • a nose 22 on the cover rail 21 can be seen at the upper rear end, which cooperates with a lock on the holding part 20, which is actuated by a locking lever 23.
  • An elongated support component 24 can also be seen from FIG. 2.
  • the structure of the magazine 18 can be seen in more detail from the sectional representations according to FIGS. 3, 4, 6 and 7.
  • the carrier component 24, which is constricted in the middle at 25 to save material, has an upper groove 26a and a lower groove 26b.
  • the cover rail 21 is C-shaped in section. Their inwardly bent free edges 27a, 27b engage in the grooves 26a, 26b. The thickness of the free edges 27a, 27b is considerably smaller than the width of the nuts 26a, 26b.
  • the legs of the cover rail 21 bear against the parts of the carrier component 24 lying within the rail, so that the rail 21 is guided by the carrier component during a lateral movement transverse to the longitudinal axis relative to the carrier component 24, as shown in FIGS. 3 and 4.
  • the carrier component 24 has on the lower section lying in the rail 21 an extension 28 on which a guide bar 29 is attached.
  • an inner surface 30 forms the side wall of a guide channel for pins 31.
  • the lower limit of the guide channel is provided by the upper surface of the extension 28.
  • the guide channel is on the side opposite the surface 30 limited by the facing surface of the guide bar 29.
  • An inverted U-shaped pusher 32 rests on the guide bar and interacts with a spring in a manner not described. The inner leg of the pusher 32 engages the rear pin 31.
  • a guide component 33 is fastened on the inside in a manner not shown in detail. On average, it is a lying U-profile, with the recess facing the guide channel.
  • a packet of three slats 34 with a rectangular cross section is stored in the recess.
  • the structure of the slats is shown in Figures 10 and 11 in more detail.
  • FIG. 10 shows a lamella 34a made of metal and
  • FIG. 11 shows a lamella 34b made of plastic.
  • the fins 34a, 34b are flat bars with a rectangular cross-section over most of their length. At the ends they are cut out at 35a and 35b.
  • An attachment 36a or 36b adjoins the recess.
  • Elongated holes 37a and 37b are formed in lugs 36a and 36b, respectively.
  • Rod springs 38a and 38b are arranged in the recesses.
  • the bar spring 38a is fastened by welding or by riveting or by means of a screw.
  • the bar spring 38b is formed in one piece with the lamella 34b.
  • a guide pin extends through the elongated holes 37a and 37b at the ends through a plate pack, which is shown in broken lines at 39 in FIGS. 3, 4 and 6.
  • the pins 34 are connected to the legs of the guide part 33.
  • the bar springs 38 of the slats 34 are supported on the bottom of the recess and therefore press the slats 34 in the direction of the opposite guide channel wall 30.
  • the elongated holes 37 limit the end position.
  • the longitudinal surfaces 40 of the slats 34 which face the guide channel, are aligned with the end surface of the upper leg 41 of the guide part 33.
  • the cover rail 21 occupy two limit positions relative to the carrier component 24 can. According to the illustration according to FIGS. 3 and 6, the two parts are maximally displaced towards one another. This is the case with the closed cover rail 21 according to FIG. 1.
  • cover rail 21 and support member 24 are at a maximum distance from each other. This is the case with the cover rail 21 partially open according to FIG. 2.
  • FIGS. 8 and 9 An alternative embodiment of the magazine described above is shown in FIGS. 8 and 9.
  • the sectional representations are the same as those shown in FIGS. 6 and 7, and insofar as parts are shown the same reference numerals are used.
  • the only difference in FIGS. 8 and 9 is that a recess 30a is formed in the upper region of the guide channel wall 30 and extends over the length of the carrier component 24.
  • the recess partially receives the head of a nail 42.
  • the depression 30a prevents nails from being tilted with heads.
  • a stop 50 is attached to the top of the cover rail 21 at the front end, which cooperates with a rear stop 58 at the lower end of the holding part 20 and limits the displacement of the cover rail 21 to the rear.
  • the stop 50 has a section 51 with which it projects into the groove 26a.
  • the total width of section 51 and free edge 27a of the cover rail 21 corresponds approximately to the width of the groove 26a.
  • the lower rear section 52 of the mouth tool 19 is firmly connected to the cover rail 21.
  • a projection 53 is formed in one piece with the tool section 52, which engages in the lower groove 26b.
  • the total width of shoulder 53 and free edge 27b or their thickness corresponds approximately to the width of groove 26b. 12 also shows that the free edges 27a, 27b are thickened on the inside at the rear end, as shown in dashed lines at 54.
  • the groove 26a has a wider oblique section 55 at the front end which opens into an axially parallel end section 56 which is freely open to the side.
  • a pin strip 31 can be inserted into the magazine. This can be seen in FIG. 7.
  • the distance of the lamellae 34 from the wall 30 is approximately one and a half to two times the diameter of the pins 30.
  • the rail 21 is pushed forward again. Because of the distance of the lamellae 34 from the pins 31, this can be done without obstacle.
  • the cover rail 21 performs the transverse movement described above, the slats lie against the Nails on, to the extent that they are caught by the nails. 6, the length of the pins 31 corresponds to the height of the guide channel up to approximately the underside of the upper lamella 34.
  • the thickness of the slats can be 3 mm. Pin lengths of 12, 15, 18 and 21 mm can then be processed with the driving tool shown. Manipulation in the magazine when changing the pin lengths in accordance with the specified values is therefore not necessary.
  • the carrier component 24 abuts on the inside against the mouth tool 19 and screwed to it with the aid of a screw 56. If the screw 56 is loosened and a further screw in the area of the holding part 20, the carrier component 24 can be pulled backwards by an amount, as is shown in FIG. 13. A pin guide 57 for the carrier component can be seen, which interacts with a bore in the carrier component 24. A screw connected to the holding part 20 extends through an elongated hole (not shown) in the carrier component, as a result of which the described displacement is possible. In the arrangement of the carrier component shown in FIG. 13, the drive channel (not shown) of the mouth tool 19 is freely accessible in order to remove clamped fastening means.
