Definitions
- the invention relates to a hand tool with a tool part and with a portion of the tool part enclosing and torque-connected to this handle.
- the invention further relates to a method for producing such a hand tool.
- Such hand tools are, for example, screwdrivers.
- the tool part in such a hand tool designed as a screwdriver is the blade, which has a torque transmission contour on its actuation-side end.
- the torque transmission contour can be designed differently, for example as a slot contour, as a cross contour or as any other contour which is adapted to transmit a torque to a corresponding counter-contour having screw.
- the end opposite the actuation-side end of the blade with its torque transmission contour is flattened like a spatula. This end is used for the torque-locking connection of a handle.
- a handle is typically a plastic part. This is molded around the spatula-like flattened end portion of the blade in a plastic molding tool.
- the handle itself is made of two different plastic components, wherein the difference in the two plastic components may be due to a different color and / or by a different hardness. Different colors are used to give the handle of such a hand tool in its outer surface a specific design. Different hardnesses are used to create a certain feel when gripped and when using the handle. If different plastics are used for the formation of such a handle, with usually only two different plastics being used, this takes place by means of a so-called two-component injection molding process. This means that in a first step to create the handle, the plastic tool geometry is set to the geometry of the first plastic component. Then the tool geometry is changed.
- the second plastic component can be urgeformt. It is also possible to move the screwdriver grip semi-finished product into another tool shape.
- the second plastic component fills the remaining cavities in the mold cavity.
- the manufacturing process for producing a hand tool with a thus created handle made of two plastic components is due to the necessary tool conversion for retooling the tool from the required for the Urformung the first plastic component geometry of the cavity in the geometry of the cavity, which is needed for prototyping the second plastic component is also time consuming. Correspondingly long are the cycle times to be realized with such a method. If a change in shape or design is made with respect to the handle, this means that new tools must be produced.
- the invention is therefore the object of proposing a hand tool with a multi-component handle and a method for producing such a hand tool that can be produced not only in shorter cycle times, but in the one not insignificantly reduced effort form and / or design changes in the design of the handle can be made.
- the device-related object is achieved according to the invention by a hand tool of the type mentioned, in which the tool part at least partially in a framed by the handle section serving for torque-locking connection of the handle terminal contour and wherein the handle is a connectable to the terminal contour and this torque-locking enclosing inner handle, wherein when pushed onto the terminal contour inner Grip between two parts one or more, outwardly open Vergusskanäle are provided, and an outer handle made of plastic, which formed by means of Kunststoffurform revitalizes to the unit of tool part with connected to its connection contour inner handle and the at least one casting channel at least partially the outer handle forming plastic material is filled.
- the method-related object is achieved by a method having the features of claim 14.
- the inner handle forms the coupling piece between the tool part with its connection contour and the outer handle.
- This inner handle which is typically in one piece, but can easily consist of several individual parts, can be connected to the connecting contour of the tool part.
- the inner handle on the connection contour in the longitudinal axial direction of the tool part can be pushed onto this.
- the inner handle, if designed in several parts is composed of two shells which, when assembled, surround the connection contour of the tool part in a torque-locking manner.
- the connectability of the inner handle to the connection contour of the tool part requires that the inner handle is not molded around the connection contour of the tool part, but is made independently of the connection contour.
- the inner handle is a plastic part.
- inner grips made of other materials can be used. Inner grips made of plastic will usually prefer due to the cost-effective production and greater variability in the material used, especially in the training of different geometries.
- connection contour of the tool part is designed so that the inner handle is torque-tight connected thereto.
- the connection contour is a plastic body encased around a section of the tool part, for example the screwdriver blade, formed as a polygon so that the inner grip element can be connected to the connection contour in a torque-locking manner with an inner complementary polygonal contour.
- the two polygonal contours are adapted to each other in such a way that a torque transmission from the inner handle is given to the connection contour. This does not have the necessary prerequisite that the inner connecting contour of the inner handle and the polygonal contour of the connecting piece must have the same geometry.
- Such a polygonal contour may be formed, for example, as a hexagon. This contour extends in the longitudinal extension of the tool part.
- the inner contour of the handle and / or the outer contour of the connection contour are coordinated with each other so that one or more Vergusskanäle remain free between them.
- the potting channels are used to connect the inner handle with the connection contour of the tool part, so that both parts are permanently connected to each other. Ultimately, these two parts can then no longer be separated from each other without destroying each other.
- the potting channels are potted with a compound intended for the compound.
- the handle of this hand tool has in addition to the inner handle on an outer handle, which is a plastic part and which is urgeformt to the inner handle.
- This process is performed after the inner handle is connected to the terminal contour.
- the casting channel (s) open to the outside are filled, so that in the case of the original shape of the outer grip piece the inner grip piece is simultaneously connected to the connecting contour of the tool part. Therefore, in principle for the connection of the inner handle to the terminal contour no separate manufacturing step and not the use of another material is needed.
- the patch on the contour of the tool part inner handle which thus addressed in this process as a lost inner Kunststoffurformwerkmaschinegne.
- the terminal contour and the outer handle are formed in a plastic injection molding tool in successive stages. produced. Due to the relatively simple geometries to be formed, this can be a so-called open-close tool, ie a tool which basically works without a slide or the like.
- the inner gripping piece produced in a separate tool typically produced in a separate injection-molded plastic tool, can also have a complicated surface geometry, as can perforations, channels, undercuts or the like. Due to the production of the inner handle in a separate plastic injection molding tool, the on-off tool otherwise used for production can be driven at a higher cycle frequency. In this tool, the semi-finished products comprising the tool part and placed on the connection contour of the tool part inner handle are inserted.
- one and the same original mold for forming the externa ßeren handle can be used to overmold also different tool parts in terms of their diameter.
- different inner grips for different diameters of the tool parts.
- the inner handle which then for the externa ßere handle the inner tool surface without having to make changes to the on-to-tool, also different handle designs.
- the inner handle In the original forms of the externa ßeren handle piece remaining in the mold cavity cavities are filled with the plastic material used to create the externa ßeren handle, so also the already mentioned Vergusskanäle.
- the design of the tool handle can be varied. Such a variation is possible, for example with regard to the geometry of surface portions of the inner handle, which also represent a portion of its outer surface in the finished tool handle.
- the inner handle preferably has a greater hardness (Shore) than the outer handle. In this way, such a handle can be equipped with a special grip. In another embodiment, it is provided that the inner handle has a lower hardness than the outer handle. In such an embodiment, the inner handle acts like a pillow that conforms to the hand of a person using the handle. In such an embodiment, the inner handle is typically totally enclosed by the outer handle, which is also compliant enough for the yielding cushion effect of the inner handle to be effective. Nevertheless, on the harder outer and with respect to the softer inner handle a shell-forming outer handle high torque can be introduced into the handle and thus into the tool.
- the inner handle is pushed onto the connection contour of the tool part, in a translatory Aufschiebeddling in the longitudinal extent of the tool part.
- the inner handle on the connection contour is fixed by a catch.
- the connecting contour carries two diametrically opposite, arranged on the outside latches, which are elastically adjustable in the radial direction.
- the inner handle carries at a respective location in each case a latching recess, in each of which a catch engages when the inner handle is in its intended position on the connection contour.
- this handle concept is especially suitable for the fact that in some areas the outer surface of the inner handle also represents the surface of the tool handle.
- these surface areas which are not to be coated by the further plastic component for creating the outer handle, it is provided in a preferred embodiment that these areas of the inner handle are delimited by a circumferential sealing lip.
- This sealing lip acts against the inner wall of the cavity for molding the outer handle and lies under a certain bias on the inner wall of the plastic forming tool.
- Such a sealing lip can be provided by a corresponding material thinning of the inner grip.
- the outer surface of the handle is provided by parts of the inner handle, it may be provided that these areas have a special design and / or geometry.
- a tool handle it is provided as a screwdriver handle that a plurality of circumferential rotational drive beads distributed on the outside are arranged in those regions of the inner grip piece which form the outer surface of the screwdriver handle.
- Such a configuration is not limited to the described embodiment of this tool handle as a screwdriver handle, but can also be used in other tool handles. At least some of these rotary body beads are inclined at least in sections relative to the handle longitudinal axis in their extension in the direction of the blade of the screwdriver handle counter to the screwing-in direction.
- rotational driving beads on their side facing away from the screwing-in direction at a low angle with respect to the envelope surface enveloping the handle inclined footprint.
- rotational driving beads are present, which are inclined with their longitudinal extent relative to the longitudinal extent of the handle and thus, in contrast to Drehit Vietnamesesicken from the prior art are not parallel to the longitudinal extent of the handle.
- the inclination of the longitudinal extension of these rotational drive beads is directed against the screwing when viewed from its rear end towards the blade.
- These rotational driving beads have at their side facing the direction of screwing a footprint, which is inclined at a slight angle to the lateral surface of the handle or the handle enveloping the lateral surface.
- Such a rotational driving bead designed in this way ensures not only an introduction of a torque in the screwdriver handle for screwing a screw due to the inclined execution of such a rotary driving bead with respect to the longitudinal extent of the screwdriver handle at the same time providing a longitudinal axial direction of the screwdriver handle towards the torque transmission contour of the blade acting moment. This moment serves to maintain engagement of the blade of the screwdriver with the rotary driving contour of the screw head when torque is applied.
- these rotational driving beads is a part of the torque introduced for the required Engaged moment. In this respect, it is not absolutely necessary in such a screwdriver handle to spend an additional pressing force. For particularly stiff screws, this may also be useful.
- this provided for the engagement position torque is coupled to the coupled torque.
- the footprint provided counter to the screwing-in direction is inclined at only a slight angle relative to the lateral surface of the handle or the lateral surface enveloping the handle. This prevents the skin of the inside of the hand from being pinched in the event of possible slippage between the hand of a person using the screwdriver and the screwdriver handle.
- inclined rotational driving beads can be provided in addition to already existing rotary driving beads, which follow with respect to their longitudinal extent of the longitudinal extension of the screwdriver handle. Likewise, it is possible that the screwdriver handle has only in the aforementioned manner inclined rotational driving beads.
- the rotational driving beads are curved with respect to their longitudinal extent, wherein the angle between the respective portion of the rotary driving bead and the handle longitudinal axis increases in the direction of the blade. Investigations have shown that it is sufficient if these spaced opposite to the longitudinal axis of rotary driving beads on a central portion of the screwdriver handle with respect to its Longitudinal are limited. Thus, these rotational driving beads are typically in the area of the screwdriver handle in which this has its largest diameter in relation to its typical barrel shape, in which portion of the screwdriver handle the maximum torque is applied.
- a particularly preferred embodiment of such a screwdriver handle is seen in that the screwdriver handle has a circumferentially roundish surface, in particular a cross-sectional geometry in which a plurality, typically three Zykloidbogen- sections are provided, which are interconnected by sections having a much smaller radius of curvature are.
- the rotational driving beads worked out by introduced into the outer surface depressions, in the field of Zykloidbögen.
- the lateral surface enveloping the tool handle is preferably not changed in terms of its geometry, so that the rotational spot beads are not ribs, beads or the like projecting beyond the lateral surface otherwise usual for such a handle.
- a recess is typically designed in a V-shape, wherein the opening width of the flanks is relatively large and typically exceeds an angle of 1 60 °. This implies that the depth of the recesses for working out the setting bevel for the rotational driving beads need not be particularly deep in order to provide a sufficiently large footprint. It is considered sufficient if the maximum depth of such a recess for forming such a footprint is 0.5 mm.
- the footprint Due to the small inclination of the footprint this is despite the small depth of the footprint working out recess sufficiently large, i. the footprint has a sufficient extension from the depth line of the recess to the upper end of the rotary drive link to derive one of an applied torque the desired longitudinal moment.
- the extent of that footprint of the rotary driving bead, which is opposite to the one has screwing direction, from its pointing to the rear end of the screwdriver handle end to its other end in the extension of the depth of the recess forming this footprint successively increases towards the upper conclusion.

- the sealing lip 1 6 is located at the boundary between these two areas.
- the sealing lip 16 is a thin material extension which extends over the surface 15 by a few tenths of a millimeter.
- the sealing lip 1 6 acts in the creation of the outer handle 6 against the inner wall of the mold cavity in which the outer handle 6 is urgeformt.
- Part of the inner handle 5 is, as shown in Figure 6, also a symbolism 17, through which the type of rotary driving contour 4 is symbolized. Since the rotational engagement contour 4 is a cross contour, the symbol 17 is also executed as a cross.
- the recognizable outer surface of the symbolism 17 in FIG. 6 is not overmolded by the synthetic material compound used to create the outer grip piece 6.
- the outer surface of the symbol 17 is also equipped with a circumferential sealing lip, as previously described at the radially facing surface portions of the inner handle 5, equipped.
