Definitions

  • the present invention relates to driving tools for driving studs, nails or the like into walls, metal plates etc. and, more particularly, concerns a safety arrangement for such driving tools.
  • driving tools of the above mentioned type it is desirable ⁇ and in most countries required that such driving tools be provided with safety means preventing an unintended firing when the trigger is accidentally contacted.
  • the driving tool will not fire when subjected to an accidental shock as for instance when the driving tool accidentally drops fro-m the work bench to the floor.
  • Safety regulations of most countries furthermore require that the driving tool be so designed that a firing can be effected only when the barrel mouth is pressed against a xed surface.
  • Some countries furthermore require that the operation of the driving tool can be effected only by using both hands to insure that the operator when firing will not have one hand in the path of the barrel mouth.
  • a still further object of this invention consists in providing a safety arrangement as set forth in the two preceding paragraphs which may also be used in connection with driving tools equipped with covering means for covering up the area around the surface into which the stud, nail or the like is to be driven.
  • Fig. 1 illustrates partly in longitudinal section an embodiment of the new driving tool for driving studs, nails or the like into walls, plates, etc., which is equipped with safety arrangements according to the present invention.
  • Fig. 2 shows in longitudinal section about the central portion of Fig. 1 but on a larger scale than the latter.
  • Fig. 3 is a fragmentary side elevation of a modification of the safety arrangement shown in Figs. 1 and 2.
  • Fig. 4 shows a longitudinal section through the front part of the driving tool of Fig. 1.
  • Figs. 5 and 6 illustrate in section a modification of the front part of the tool of Fig. 4 in two different positions.
  • the driving tool illustrated therein is a driving tool with a variable firing power.
  • the driving tool comprises a barrel 1 provided with a threaded portion'Z threaded'ly engaging a correspondingly threaded sleeve 3.
  • the space 4 between the barrel 1 and the cartridge chamber 6e may be varied thereby varying the ring power.
  • the casing 6 surrounding the barrel is provided with a window 5 which latter may be provided with a scale or a mark.
  • the barrel mouth In order to allow the tiring of a stud, the barrel mouth must rest against the surface into which the stud is to be driven, and while the barrel 1 together with the sleeve 3 retains its position, the casing 6 must against the thrust of a spring 7 be pushed forwardly as far ⁇ as the space 8 between the cartridge chamber 6e and the casing f will allow, said spring 7 being arranged within a cylindrical cutout of the sleeve 3.
  • This safety mechanism comprises a control sleeve 9 surrounding the casing 6 and the barrel 1, said control sleeve 9 being longitudinally slidably mounted on the casing 6.
  • a latch or locking element for instance a ball 10 is provided in a corresponding cutout of the casing 6 and partly engages a longitudinal groove 11 the upper end of which has a widened portion 11a.
  • the lower portion of the control sleeve 9 is provided with an annular cutout 11b in which is mounted a spring 13.
  • the upper end of spring 13 engages the upper end of the cutout 11b, whereas the lower end of spring 13 engages a ring 12 which is iixedly connected in any convenient manner to the casing 6.
  • the lower end of the control sleeve 9 is provided with an inwardly directed flange 11C which by engagement with ring 12 limits the upward movement of the control sleeve 9. It will be appreciated that the spring 13 continuously urges the control sleeve 9 to move upwardly into the position shown in Fig. 1. As will be evident from Fig.
  • rneans may be provided which will hold Vthe control sleeve 9 in its downwardly pressed position. This may be effected in any convenient manner for instance by a bayonet joint connection 6a, 9a between the control sleeve 9 and the casing 6. Suchan arrangement is shown for instance in Fig. 3.
  • the lower end of the driving tool is provided with a plate 101 which extends around the lower portion of the barrel and takes the place of bell-shaped cups heretofore customary for covering up the area into which the stud, nail or the like is to be driven.
  • the plate 101 is connected to a disc 103 which in its turn is connected to a sleeve 107, for instance by welding. lf desired, sleeve 107 and disc 103 may be integral With each other.
  • Sleeve 107 surrounds the lower portion 104 of barrel 1 and also surrounds a portion of the casing 6 of the driving tool. As stated above, safety requirements demand that the driving tool can be fired only when the barrel is pressed against a fixed support in order to prevent the driving tool from being used as firearm.
  • the sleeve 107 be non-detachably connected to the casing 6.
  • the casing 6 is provided with an annular groove 109, whereas the upper end of the sleeve 107 has an inwardly directed flange 110 which may be obtained for instance by welding in a corresponding ring.
  • the bore of the flange 110 is such that during the assembly of the tool the casing 6 can just be Vslid through said bore, while a small space will remain between the interior of the sleeve 107 and the inwardly extending portion of the casing 6.
  • a spring ring 111 is placed into the groove 109.
  • the ends of the spring ring 111 are spaced from each other by a distance 112 of such magnitude that the ring can be compressed so that it will entirely fit into the groove 109 without the edges of said ring protruding beyond the outer edges of groove 109.
  • the ring 111 is then held in this position by an appropriate tool such as a pair of pliers and the fiange 110 is slipped over the spring ring 111.
  • a leaf spring 114 Connected to the casing 6 in any convenient manner is a leaf spring 114 the lower end of which has connected thereto a hook-shaped finger 113 which is accessible from the outside through a slot 108:1 in the casing 6.
  • the finger-113 is by means of the spring 114 continuously urged into the position it occupies in Fig. 4. As will be seen from the drawing, in this position the finger 113 is in thepath ofthe upwardmovement of sleeve 107 and thus prevents the sleeve 107 from being moved in the direction of the arrow Z.
  • the finger 113 serves'as ⁇ abutment for the sleeve 107 and thus prevents a withdrawalof the plate 106 from the area into which the stud is to Vbedriven.
  • the plates 101 and l106 can be temporarily withdrawn from their forward position so as to give a clear view of the proper loca-tion 'of the area,I thus ⁇ permitting exact aimingjof the tool. This is accomplished by merely pressing the finger 113 inwardly and pulling the sleeve 107 back over said inwardly pressed finger 113.
  • the nger 113 is provided with an interior nose 116 which, when Y the linger 113 is pressed inwardly, engages an annular groove .11S of the lower portion 104 of barrel 1, thereby blocking any relative displacement of the casing 6, as long as the fsleeve 107 is partially slipped over the finger .113, ⁇ i.e. as long as the plates 101 and 106 have been withdrawn from said area.
  • the tool cannot befired during the aiming when the plates 101 and 106 are withdrawn.
  • the sleeve 107 is released for return of the plates 101 and 106 to the forward position .shown in Figs. l and 4 under the action of spring 118 within said sleeve. The tool can now be fired.
  • Figs. 5 and 6 illustrate a protective plate connection which is somewhat modified over that of Fig. 4. Also in this instance, the protective plate must be in its proper protective'position when the tool is being fired.
  • the lower portion ⁇ 104' ofthe barrel is provided with a groove 61, while the casing 6? is provided with a passage 63.
  • the plate 103 has connected thereto a sleeve 107 slidably mounted von casing 6 and provided with a groove 62.
  • a ball 64 is located in passage 63. The arrangement is such that the passage 63 together with groove 61 can fully accommodate ball 64. Similarly, passage 63 together with groove 62 can fully accommodate ball 64.
  • a driving tool having a casing and being operable to drive studs, nails, and the like into walls, plates, and the like, the combination of: a barrel mounted in said casing, said casing being movable relative to the barrel from a normal position into a second position and being provided with a circular groove, a sleeve surrounding a portion of said casing and being manually displacable thereon, spring ring means mounted in said circular groove and non-detachably interconnecting said sleeve and said casing While allowing movement of said sleeve on said casing, plate means iXedly connected to said sleeve and having a passage therethrough for said barrel, and control means carried by said casing and operable selectively to block movement of said sleeve relative to said casing while allowing movement of said casing or to block movement of said casing relative to said barrel while allowing movement of said sleeve.
