Definitions

  • the invention relates to a ratchet with a ratchet designed as a ratchet, which is articulated on a handle, which has an extension piece which is penetrated by a hinge axis lying in the plane of rotation of the ratchet and which on its opposite narrow sides perpendicular to the plane of rotation by an articulated fork of the handle is bordered, which can be angled with respect to the plane of rotation of the ratchet, and with a securing device for the selected grip angle, which has a manually adjustable bolt, to which a ring of locking openings on the extension piece, which is perpendicular to the plane of rotation of the ratchet, is assigned, the bolt from the The fork base of the handle stem protrudes and can be retracted against the force of a spring to the fork base by means of a slide guided in a slot of the handle handle and provided with a grip surface.
  • the invention aims to improve the generic ratchet in such a way that the handle bend and the locking of the angled position can be carried out with only one hand.
  • the invention provides that the handle handle is provided with a central guide channel extending to the region of the handle and that the bolt consists of a rod which can be displaced in the guide channel and which is rigidly connected to a slide located within the thumb reach of the handle.
  • the rod is at an angle of about 20 o to 90 o, preferably 30 o, rotatable and that it is guided in an angled grip handle slot valve, the axial from a front portion and a rear radial part.
  • the slide expediently comprises a ring which surrounds the handle, which is provided with a thumb recess which has grip surfaces which rise both towards the rear and in the circumferential directions.
  • the slide is arranged in a cutout of the front end of the handle, the handle being provided at the front end with a thumb bead having the cutout and the slide having a handle end lying in the basic position within the thumb bead cutout .
  • the end of the handle fills the thumb bulge approximately flush with the contours.
  • the rod can have a locking lug in the form of a screwdriver blade at its end protruding from the fork base and the locking openings can be designed as slots.
  • the locking lug or the slots have bevels on the edge or weakly diverging side surfaces.
  • the ratchet shown in FIGS. 1 to 5 consists of a handle handle 1 with a handle 2, and a working head 3 with a square piece 4 mounted as a ratchet, which are pivoted to one another via an articulated axis 5.
  • the handle 1 is designed at one end as a bearing fork 6, which surrounds an attachment 7 of the working head 3 provided with a bore for the articulated axis 5.
  • the handle 1 is pivotable about the hinge axis 5 and thus angled relative to the rotary plane of the ratchet.
  • the handle 1 is provided with a central, up to about the handle 2 guide channel 8 for a rod 9, which protrudes at its front end from the fork base 10 and on a widened head 11 carries a locking nose 12 designed in the manner of a screwdriver blade, the one perpendicular to the ratchet plane of the ring of locking openings 13 on the extension 7 is assigned.
  • the rod 9 is rigidly connected by means of a diametrical pin 14 to an annular slide 15 enclosing the handle shaft 1, the diametrical pin 14 penetrating two angled slots 16, 17 of the handle shaft 1.
  • Each grip slot consists of a front, axial part 17a and a rear, radially directed slot part 17b.
  • a compression spring 19 is clamped between the rear end face of the rod 9 and the bottom 18 of the blind hole-like guide channel 8, which loads the rod 9 in the direction of an engagement of the locking lug 12 in one of the locking openings 13, as shown in FIG. 3.
  • the ring or slider 15 which is provided with a suitable thumb recess 20, which has gripping surfaces 21, 22, 23 rising both to the rear and in the circumferential direction, with the thumb of the hand holding the handle 2 against the force of
  • the spring 19 is initially withdrawn axially, so that the nose 12 emerges from the locking opening and a desired handle angle can be set.
  • the slide 15 can about 5 o are rotated in the retracted position, after which the locking device moves into the position according to FIG. 5, in which the locking lug 12 is pulled out of the locking opening of the extension piece 7 and this unlocked position by the contact of the diametral pin 14 on the wall of the radial slot part 17b is secured.
  • Fig. 6 illustrates the contours of a slot-shaped locking opening 13, which here is provided on its longitudinal edges with a chamfer 24 for easier insertion of the locking lug 12, which is also provided with chamfers 25 on its two longitudinal edges.
  • a locking lug 12 ' can be assigned to the locking opening 13, the front end of which is semicylindrical.
  • FIG. 7 A very technically advantageous embodiment of the locking opening and associated locking lug is shown in Fig. 7, in which the locking opening 13 'and the locking lug 2' each have weakly diverging side surfaces 26/26 and 27/27 and thus rounded V-grooves or V - Form wedges.
  • the handle 29 is provided with a cutout 31 at its front end, which has a circumferential thumb bead 30, in which the handle end 32 of the slide 33 for actuating the locking bar 34 is arranged in the basic position.
  • the handle end 32 fills the thumb bulge cutout 31 approximately flush with the contour and is rigidly connected to the locking bar 34 by means of the pin 14 which penetrates an axial elongated hole 35 in the tubular stem 36.
