Definitions
- the invention relates to a hand-held tool holder for holding chisel tools with a tubular guide part for axial guidance of the chisel tool and a holding part, which comprises the guide part and on its, the machining side opposite end, has a protective flange.
- Hand-held tool holders of the type mentioned serve to guide chisel tools.
- the longitudinal end of the chisel tool is held by a hammer that is guided with one hand acted upon.
- Areas of application of such hand-held tool holders For example, chisel work in places where electricity is not available is small Reworking or dosed work on an unknown surface.
- a hand-held tool holder of the type described is disclosed in DE 2 610 663 A1.
- This known hand-held tool holder consists of a one-piece, tubular Plastic part that holds a chisel tool, for example.
- the guide part consists, for example, of four webs that extend into the interior of the tool holder extend. If a chisel tool is inserted into this known tool holder, so the bars avoid the chisel tool and hold it frictionally. Since often Don't hit the center of the length of the handheld tool holder with the hammer can cause injury to the hand with which the Tool holder is held come. To prevent this from happening, is described on Tool holder, for example, on the opposite of the machining direction End of a holding part comprising the guide part, a protective flange arranged, which shields the hand holding the tool holder.
- This known one-piece, hand-held tool holder offers the The advantage of economical production, however, is the secure holding of the chisel tool not guaranteed in every case. Due to the frictional mounting of the chisel tool is, for example, an uncontrolled one, particularly in the case of heavy use Sliding the chisel tool possible in the known hand-held tool holder.
- a further disadvantage of this known solution is that between the chisel tool and there is feedback from the hammer being used. The executing person therefore feels a setback with every hammer blow from the one used Hammer.
- the present invention has for its object a hand-held tool holder to create that decouples the chisel tool from the hammer used and also allows the chisel tool to be used safely to lead.
- the hand-held tool holder should be economical to manufacture.
- the object is achieved in that the guide part as a guide tube is formed with a locking mechanism.
- the locking mechanism preferably has an at least partially the guide tube Comprehensive, movable against the force of an elastic element, actuator and a radially displaceable locking element.
- the locking element can be brought into a guide groove of the insertion end of a chisel tool, for example and thus prevents the chisel tool from falling out due to an axially limited guide out of the guide tube. Due to the radial displaceability of the locking element becomes a simple loosening of the guide between the chisel tools used and the hand-held tool holder. With the help of the relocatable This process can be controlled by the actuating part.
- the elastic element guarantees that the locking element in the rest position when the chisel tool is inserted with it and the tool holder forms an axially limited guide.
- the locking mechanism is expediently designed in such a way that it is trouble-free works and is economically producible.
- the leadership of the locking element takes over a radial bore in the guide tube.
- the locking element preferably has a radial extension projecting beyond the wall thickness of the guide tube. This ensures that the locking element is always guided through the bore.
- the locking element is advantageously spherical.
- the spherical shape prevents jamming of the locking element in the bore and has a manufacturing effect positive because, for example, the assembly of the tool holder is simplified becomes.
- the actuating part is expediently displaceable in the machining direction the user can hold the protective flange of the Find the tool holder and apply the force required to move the operating part, which contributes to the handiness of the tool holder.
- the actuating part form as a sleeve.
- the guide tube serves as Guide for the operating part.
- the actuating part preferably has a pocket for receiving the locking element serves and has at least a depth which is the difference between the radial extension of the locking element and the wall thickness of the guide tube corresponds.
- the locking mechanism is preferably at a distance from the machining side opposite end of the guide tube is arranged and for bridging the distance within the guide tube an axially guided striking die is the feedback between the chisel tool and the one used Hammer interrupted.
- the use of the striker prevents the deformation and / or material fatigue on the chisel tool.
- the anvil is advantageously axially limited by means of stop shoulders and counter shoulders movably mounted. Thus it is secured against falling out of the guide tube.
- the drawing shows a hand-held tool holder according to the invention for guidance of a partly shown chisel tool 1 and a connecting piece connected to it 5, consisting of a holding part 3, which is designed as a guide tube 2 guide part includes and at its processing end opposite one Protection flange 4 has.
- the guide tube 2 is with a locking mechanism designated overall by 6 Mistake.
- the locking mechanism 6 has an actuating part 7, which is designed as a sleeve and a spherical locking element 8.
- the locking element 8 is radially displaceably mounted in a bore 15 of the guide tube 2 and extends radially beyond the wall thickness of the guide tube 2.
- the bore 15 is in the interior of the guide tube 2 adjacent area is formed so narrow that their clear diameter is smaller than the diameter of the locking element 8.
- the actuating part 7 is against the force of an elastic element 9, which acts as a spring is formed, slidably mounted in the machining direction B. Under the power of elastic element, the actuating part 7 closes the bore 15 on the outer peripheral surface of the guide tube 2 at least partially.
- the guide tube 2 has stop shoulders 14 which, together with counter shoulders 13 formed on the die 5 limit the axial movement of the striker 5.
- the stop shoulders 14 are for example formed by a snap ring which is arranged in a recess in the guide tube 2. The depth of the recess is to be dimensioned such that the snap ring partially covers it protrudes radially.
