Definitions
- the invention relates to a ratchet with a ratchet designed as a ratchet, articulated on a handle handle provided with 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 of an articulated fork of the handle, which can be angled relative to the plane of rotation of the ratchet, and with a securing device for the selected angle of the handle, which has a hand-adjustable latch to which a ring of locking openings on the extension piece, which is perpendicular to the plane of rotation of the ratchet, is assigned, whereby the latch protrudes from the fork base of the handle stem 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 stem and provided with a grip surface.
- GB-A-550 038 discloses an open-ended wrench which consists of a work head pivotably mounted on a handle and in which the handle can be angled relative to the jaw within the rotating plane of the open-end wrench.
- the working head has a rear toothed ring, in which a locking member which is mounted in an axial channel of the handle shaft engages and which can be unlocked by means of a sliding ring which surrounds the handle shaft.
- the sliding ring is located at a distance in front of the handle, so that even with a one-hand operation, the handle hand must be pushed forward from the handle or at least very widely spread, which is the case with the angling there within the Open-end wrench level should still be feasible, but not with the generic ratchet, in which the handle is angled perpendicular to the level of rotation of the ratchet and must be raised or lowered accordingly.
- bendable ratchets are also known, in which the locking or unlocking of the handle on the working head is carried out by turning the handle to be uncoupled. These creak are just bendable using both hands.
- these embodiments require a relatively complex kinematics for translating the rotary movement of the handle into a linear feed movement of the locking lug.
- the invention has for its object to improve the generic ratchet in such a way that the handle bend and the locking of the angled position can be carried out in a convenient manner with only one hand.
- the handle is provided with a central guide channel extending to the region of the handle and the latch has a rod which can be moved in the guide channel and carries the slide, and that the handle has a thumb bead on its working head facing the working head End is provided with a cutout which receives the slider in its basic position approximately flush with the thumb bead.
- the slider lying in the area of the thumb bead can be actuated with the thumb of the same hand with which the handle is grasped, without moving this hand, the bolt being withdrawn from the locking openings for unlocking, or released for re-engagement under the action of the spring becomes.
- the fact that the slider is now flush with the contour within the contour of the thumb bead also ensures that the slider does not collide with a projecting one Corner or the like is unintentionally transferred to an unlocking position.
- the ratchet consists of only a few, easily assembled parts, so that it can be manufactured inexpensively.
- 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 Fig. 1 to 4 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 pivotally hinged to one another via an articulated axis 5.
- the handle shaft 1 is formed at one end as a bearing fork 6, which surrounds an attachment piece 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 attachment 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 diametral pin 14 passing through a slot 16 in the handle shaft 1.
- a compression spring 18 is clamped in the blind hole-like guide channel 8 and 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 slide 15 is pulled back axially with the thumb of the hand gripping the handle 2 against the force of the compression spring 18, so that the nose 12 emerges from the locking opening and a desired handle angle can be set.
- the handle 2 is provided at its front end with a circumferential thumb bead 19 with a cutout 20 in which the handle end of the slide 15 for actuating the locking bar 9 is arranged in the basic position.
- the slider 15 fills the thumb bead cutout 20 approximately flush with the contour and is rigidly connected to the locking bar 9 by means of the pin 14 which penetrates the axial slot 16 in the tubular stem 1.
- Fig. 5 illustrates the contours of a slot-shaped locking opening 13, which is here provided on its longitudinal edges with a chamfer 21 for easier insertion of the locking lug 12, which is also provided with chamfers 22 on its two longitudinal edges.
- a locking lug 12 ' can also be assigned to the locking opening 13, the front end of which is rounded off in a semi-cylindrical manner.
- FIG. 6 A production-technically very favorable embodiment of the locking opening and associated locking lug is shown in FIG. 6, in which the locking opening 13 'and the locking lug 12''each have weakly diverging side surfaces 23/23 and 24/24 and thus have rounded V-grooves or Form V-wedges.
