Definitions
- the invention relates to a screwdriver with a arranged in a handle transmission gear for multiplying a from the handle on a blade protruding from the handle or on a chuck for receiving a blade transmitting angle of rotation and with a locking means.
- a screwdriver of the generic type is known from DE 35 00 127.
- the screwdriver described there has a handle consisting of two handle sections.
- a section facing Griffab there is a planetary gear with which a rotary movement of the handle can be carried over to a rotary movement of the blade in a speed-increasing manner.
- a lock inside the handle that can be used to switch left and right rotation.
- the screwing tool has a blocking member.
- the blocking member can be relocated from a free position in which the transmission gear is effective, in a blocking position in which the transmission gear is no longer effective. In the release position, an angle of rotation applied to the handle is transferred from the transmission gear to the blade or the chuck for receiving the blade, increasing the angle of rotation.
- the screwing tool according to the invention can have two handle sections which can be rotated against each other in the release position of the blocking member and which are kinematically rigidly tied to one another in the blocking position of the blocking member.
- the blocking member can be displaced axially in relation to a direction in which the handle or the blade extends.
- the two handle sections can be formed in one piece or in several pieces. You can in particular consist of several parts plugged together.
- the first handle section consists of two axially interconnected parts.
- the blocking member can be displaceably assigned to the handle section pointing away from the blade and can be arranged in particular in the area of the front end of the handle, the front end of the handle body forming the second handle section having a front side opening into which a push button is arranged, in particular inserted, with which the blocking member is displaceable.
- the push button can be displaced against the elastic restoring force of a push button spring.
- the push button is preferably designed as a button, which after each actuation from an initial position, which is accompanied by an elastic deformation of the push button spring, returns to its original position, in which it is flush in the particular curved face of the Griffab section.
- the reduction gear is designed as a planetary gear.
- the reduction gear preferably has two gear levels. In a first gear level there is a first gear, in particular a sun gear with large-diameter teeth.
- This large-diameter gear meshes with small-diameter gears of second gears, in particular planet gears.
- the diametrically small gears of the second gears are rotatably connected to diametrically large gears of the second gears, which lie in a second plane in which a third gear, which is in particular a second, small-diameter sun gear is arranged.
- the large-diameter gear is non-rotatably connected to the handle portion facing away from the blade.
- the first gear wheel with a large diameter can have a coupling section which is designed in particular as a polygon and which engages in a matching cavity in the first handle section so that the coupling section is connected to the first handle section in a rotationally fixed manner.
- the third gear in particular the small-diameter sun gear, is non-rotatably connected to the blade, a chuck or a drive extension that can transmit a torque to the blade.
- the third gear in particular the small-diameter sun gear, can be connected to a drive axle, which in turn is connected to a chuck.
- the second gears are planet gears and that a web carrying the second gears is non-rotatably connected to the second handle portion, which is rotatable relative to the first handle portion in the release position of the blocking member. If the second grip section close to the blade is held by one hand, for example the left hand of a user, then take it the second gears, in particular the planet gears a stationary gear position.
- a rotational movement transmitted from the second handle section via the large-diameter gear, in particular the sun gear, to the second gear wheels, in particular planetary gears, is transmitted, for example, with a factor 1: 4 to the third gear, in particular a small sun gear, which is connected to the chuck or the blade so that when the handle is rotated on the blade or the chuck, an angle of rotation increased by a factor of 4 is transmitted.
- the handle section remote from the blade can be rotated by the other hand, in particular the right hand, of the user in both the right and the right direction.
- the blade then rotates with increased speed in the same direction of rotation.
- the screwdriver designed in this way is particularly suitable for the rapid screwing of screws with metric threads.
- the screwing tool in a preferred embodiment is a VDE screwing tool in which the chuck and the handle sections are made of an electrically insulating material, in particular special plastic.
- the blade used in the chuck has a steel core which is surrounded by an electrically insulating sheath, from which only the working tip of the screwdriving tool protrudes.
- the gears of the transmission can be made of plastic but also of metal. At least if the gears are made of metal, they can be encapsulated in an electrically insulating manner by the handle. In order to meet the VDE requirements, however, it is generally sufficient that the blade is completely coated with plastic and the chuck is designed in such a way that only such plastic-coated blades can be used there.
- the two Griffab sections can then also be made of other materials.
- the before given axially displaceable blocking member is assigned to the first handle portion.
- the blocking member can have a toothing which has at least one tooth or at least one tooth gap.
- the teeth may have a wide or front side teeth but erzahnung also be a scope V. In the Blo ckier ein this toothing engages in a counter-V erzahnung having at least a tooth gap or at least one tooth.
- the counter-toothing is preferably assigned non-rotatably to the second handle section and / or non-rotatably assigned to the web of the planetary gear.
- the planet gears extend between a counter-toothing forming the ring body and the web, the axes of the planet gears engaging in bearing openings in the ring body and the web.
- the web can be formed by a plate that carries several planet gears.
- the plate can be connected to an extension of the second handle section by means of pins.
- the pins can be molded onto the plate using the same material. But they can also be formed by the axes of the planet gears.
- the extension engages in a cavity of the first handle section and is rotatably mounted therein. The end of the extension can have hooks that get caught in the first Griffab section.
- the push button moves the blocking member in a first actuation into a blocking position.
- the blocking member is held by means of the switching element.
- the switching element is held in the displaced position by means of Haltemit tel. This is preferably done by Garvor jumps of the switching element, which grip shoulders, for example a link piece, which is set in the front opening of the first handle portion and which also holds the push button.
- the link piece can have guide grooves that guide the guide ribs of the switching element. The ends of the guide ribs pointing towards the push button form retaining projections. With sufficient axial displacement of the switching element, the ribs emerge from the guide grooves.
- the switching element can rotate by an angle of rotation at which the Haltvor jumps grip shoulders of the link piece.
- torque is applied to the switching element by the push button, so that the switching element is rotated further up to a rotational position in which the ribs are again aligned with the guide grooves, so that the switching element is shifted back to its starting position.
- the blocking member is displaced from the blocking position, the toothing of the blocking member emerging from the counter-toothing.
- the facing fronts of the push button and switching element form helically toothed sections.
- Fig. 1 is a view of an embodiment of the invention
- FIG. 2 shows the section along the line II - II in FIG. 1,
- FIG. 3 shows the section along the line III - III in FIG. 2,
- FIG. 4 shows a handle broken open in the sectional plane according to FIG. 2, in which a toothing 15 of a blocking member 5 is in no position of engagement with a counter-toothing 16 of an annular body 17,
- Fig. 5 is a second perspective broken-open representation, in which the toothing 15 is in a tooth engagement position for Ge counter-toothing 16
- Fig. 6 is a first exploded view of the essential gear elements
- FIG. 7 enlarges the detail VII in FIG. 6,
- FIG. 8 shows a second perspective view
- FIG. 9 enlarges the detail IX in FIG. 8.
- the screwing tool described in the exemplary embodiments has a handle 1 consisting of a first handle section 6 and a second handle section 7.
- the first handle section 6 consists of two handle section components 6 ', 6 ", which connect to one another to form a parting line 41
- the parting line 41 extends in the largest-diameter area of the grip section 6 and surrounds a cavity.
- the first handle portion 6 forms a rounded end face with a frontal opening 34 into which a link piece 28 is inserted.
- a pressure piece 8 which is axially displaceable with respect to an axis A and from which spring arms extend which have hooks 31 at the end which engage behind the steps 32 of the link piece 28.
- a push button spring 22 is supported on a bottom 33 of the link piece 28, which acts as a compression spring on the push button 8 in the axial direction away from the link piece 28. From the underside of the link piece 28 opposite the bottom 33, pins 39 can project, with which the link piece 28 is attached to the first grip section 6 in a rotationally fixed manner.
- the underside of the push button 8 carries a switching toothing 29 that forms the beveled edges. This switching toothing 29 cooperates with a counter-switching toothing 30 of a switching element 23.
- the switching element 23 is an essentially cylindrical body which is guided in a bottom opening of the Ku lissen Cultures 28. From a cylinder jacket wall of the switching element 23 protrude in a uniform circumference V distribution ribs 24 ', which form obliquely de retaining projections 24.
- the mode of operation of this pushbutton arrangement is as follows: Starting from an operating position in which the counter-switching toothing 30 rests against the switching toothing 29, the switching element 23 can be displaced through the opening in the bottom 33 through a linear displacement of the pushbutton 8, the ribs 24 'are guided in the guide grooves 27.
- the inclined flanks of the switching toothing 29 and counter-switching toothing 30 are angularly offset to one another that a torque is exerted on the switching element 23, which causes the switching element 23 to rotate when the ribs 24 'leave the guide grooves 27.
- the switching element 23 rotates relative to the link piece 28 and the push button 8, so that the angular offset of the switching toothing 29 to the counter-shifting toothing 30 is lifted.
- the holding projections 24 come under the holding shoulders 25, so that the switching element 23 is tied in a displaced position after the first actuation. Since the Haltevor jumps 24 and the retaining shoulders 25 run obliquely, the switching member 23 rotates slightly further in the rearward displacement. If the push button 8 is released, it shifts in the axial direction by the force of the relaxing push button spring 22 back into the starting position, the switching toothing 29 being removed from the counter-switching toothing 30.
- the inclined flanks of the switching toothing 29 engage the inclined flanks of the counter-switching toothing 30 in such a way that a torque in the same direction is exerted on the switching element 23.
- the switching toothing 29 and the opposing switching toothing 30 are angularly offset from one another. This leads to the fact that the switching member 23 can continue to rotate after a slight axial displacement into a position in which the ribs 24 'are aligned with the guide grooves 27, so that the switching member 23 can move back into the starting position.
- a blocking member 5 arranged in the end face opening 34 is also displaced in the direction of the A axis.
- the blocking member 5 is assigned to the first handle section 6 in a rotating test and has a wide-sided toothing 15 consisting of several teeth.
- a blocking member spring 26 is provided which acts on the blocking member 5 in the direction of the switching member 23, so that the blocking member spring 26 has the required force can apply to bring the switching element in the manner described above from a displaced position back into the starting position.
- a transmission gear 2 which is a planetary gear in the embodiment.
- a web 14 and an annular body 17 form a cage which supports the axes 40 of several, in the exemplary embodiment three, planet gears. From the ring body 17 protrude in the direction of the blocking member 5 teeth, which have a mating tooth training 16. The teeth 15 can be brought into mesh with the counter teeth 16 in egg NEN. Then the ring body 17, which is otherwise rotatable with respect to the first handle section 6, is tied to the first handle section 6.
- the planetary gear 2 has a large-diameter sun gear 9, which is non-rotatably connected to the first handle section via a polygonal section which forms a coupling section 20.
- the coupling section 20 is inserted in a shape-adapted cavity 21 of the first handle section.
- the blocking member spring 26 can be supported on an end face of the coupling section 20.
- the planetary gears 11 have small diameter toothings 12 which mesh with the large diameter sun gear 9.
- the small-diameter toothings 12 are non-rotatably connected with large-diameter toothings 13, which in turn mesh with a second, small-diameter sun gear 10.
- the large-diameter sun gear 9 forms a drive gear which, via the planetary gears 11, has a transmission ratio of 4: 1 with the output gear formed by the small-diameter sun gear.
- the second handle portion 7, which is rotatably assigned to the first handle portion, has an extension 19 which protrudes into a cavity of the first Griffab section.
- the extension 19 can only extend into the handle section area 6 ′′ arranged between a handle section area 6 and the second handle section 7. It is secured there by means of hooks 35 so that it can rotate axially.
- the extension 19 is connected to the cage carrying the planetary gears 11 in a rotationally fixed manner In particular, it is non-rotatably connected to the web 14 formed by a plate.
- pins 18 engage in end-face openings of the extension 19. Instead of the pin 18, however, extensions of the axes 40 can also reach into the openings.
- a lining 4 which is also tied within the second handle section 7 by means of locking means.
- a blade 3 can be inserted into the chuck 4.
- An output shaft 36 which is non-rotatably connected to the small-diameter sun rim 10 or forms the small-diameter sun gear, forms a torque transmission section 37 which is inserted in a torque transmission opening of the chuck 4 and can thus transmit a rotation to the chuck 4.
- a round section 38 of the output shaft 36 extends through the coupling section 20 or the diameter-sized sun gear 9, so that the large-diameter sun gear 9 can rotate freely relative to the output shaft 36.
- the output shaft 36 also supports the blocking member spring 26 and extends through a central opening of the blocking member 5 and protrudes into a central opening of the switching member 23. An axial displaceability of the chuck 4 and the output shaft 36 connected to it is not provided.
- the functioning of the screwing tool is as follows: In the release position, in which the toothing 15 of the blocking member 5 does not engage the counter-toothing 16, an angular speed increased by a factor of 4 can be achieved by turning the first handle section 6 and holding the second handle section 7 can be transferred from the handle to the blade 3 in both directions of rotation. Since the steel core of the blade is completely coated with an electrically insulating material except for the working tip, the chuck and the handle sections are made of an electrically insulating material, the screwdriver can be used on live parts. In the release position of the blocking member, the screwing tool assumes a rapid screwing position in which screws can be screwed into a thread at high speed.
- the screwing tool By shifting the blocking member 5 from the release position into the blocking position, in which the toothing 15 engages the counter-toothing 16, the screwing tool reaches a power screwing position. Switching between quick screwdriving position and power The screwing position takes place by actuating the push button 8 once.
- the planetary gear arrangement that is to say the ring body 17 or the web 14, is indirectly connected to the first grip section 6 in a rotationally fixed manner.
- the second handle section 7 is also connected to the first handle section 6 in a rotationally fixed manner.
