Definitions

• the invention is based on a
• Hand tool housing part according to the preamble of claim 1.
• the identification element is made of a first type of material and is glued as a sticker on a made of a second type of material housing shell part.
• the invention is based on a
• Hand tool housing part of at least two types of material with an information carrying label element.
• the identification element of a first type of material penetrates an area of a second type of material.
• Hand tool can be achieved.
• the region of the second type of material can be made particularly grippy by the marking element, especially if the marking element as a raised profile is trained. It is therefore also increased reliability of the power tool.
• the tag element passes through the region of the second type of material if it is at least substantially, i. at least 90%, surrounded by the second type of material.
• Different materials may be assigned to a same type of material if they have at least one recognizable similar property.
• Hand tool housing can be achieved if at least one of the material components has a high elasticity.
• materials with high elasticity in particular come with materials
• E modules below 2000 GPa such as soft PVC or flexible polyurethane foam into consideration.
• a risk of injury can be reduced in particular if the elastic material component has a hard
• Material component for example made of hard plastic or metal, at least partially covered.
• a particularly high grip comfort can be achieved if at least one of the types of material is a soft material containing a high proportion of natural rubber, such as a type of material known as "soft grip" type.
• advantageous heat insulation can be achieved when at least one of the types of material has heat-insulating gas inclusions.
• a particularly accurately fitting material connection between the first type of material and the second type of material can be achieved if the identification element of the first type of material is encapsulated with the second type of material. Additional manufacturing steps can be avoided if the two types of material are connected in a two-component injection molding process.
• Handheld power tool housing part can be achieved with very low initial investment, when the second type of material is bonded to the first type of material.
• identification element of the first type of material and the area of the second type of material jointly form a continuous surface, repulsion of edges at a transition between the types of material can be avoided and good cleaning properties can be achieved.
• a particularly high-quality impression can be conveyed if the first type of material and the second type of material are inlaid.

• Hand tool housing part that a
• Fig. 4 is a section along the line IV - IV by the power tool housing part of FIG.
• FIG. 1 shows an electric hand tool machine designed as a cordless screwdriver with a housing 16 made of plastic.
• the housing 16 comprises a cigar-shaped base body 20, in which a drive motor for driving a nut runner chuck 14 is arranged, and also comprises a handle 18 on which an accumulator pack 22 is releasably attached to an end facing away from the base body 20.
• the accumulator pack 22 comprises a hand-held machine tool housing part which is designed as a housing lower shell and is made of two types of material PA, TPE.
• FIG. 2 shows the hand-held power tool housing part in a separate representation detached from a remainder of the housing 16.
• the hand-held power tool housing part On a lower side, which faces away from the handle 18 when the accumulator pack 22 is fastened, the hand-held power tool housing part has an identification element 10 formed as a lettering, which is formed from a first material type PA is and that engages an area of a second material type TPE.
• Material type PA in the present embodiment is a red-colored polyamide having a smooth surface structure and a modulus of elasticity of about 2 GPa, while the second material type TPE is a black, elastic, thermoplastic elastomer with a high content of natural rubber, a grippy surface structure and a modulus of elasticity of a few hundred MPa is.
• a support part 24 of the first material type is cast (FIG. 3).
• the marking element 10 is as over a Surface of the support member 24 raised, relief-like profile formed.
• the marking element 10 and an area surrounding the marking element 10 12 are encapsulated with the second material type TPE.
• a thickness of the sprayed-on material layer of the second material type TPE in the region 12 corresponds to a height of the profile of the
• Identification element 10 so that after encapsulation the identification element 10 of the first material type PA and the region 12 of the second material type TPE form a continuous surface 26.
• the hand-held power tool housing part In order to support a material bond between the region 12 of the second material type TPE and the carrier part 24, this has a plurality of small recesses 30.
• the hand-held power tool housing part also has four screw holes 28-28 arranged in an edge region of the underside for screwing the hand-held power tool housing part to a further housing part 28 (FIG. 1) of the accumulator pack 22.
• the encapsulation of the identification element 10 with the second material type TPE can be carried out independently of the production of the carrier part 24 or in the context of a two-component injection molding process in which the carrier part 24 is produced in direct connection with the region 12.
