Definitions

  • the present invention relates to a hand tool housing with a first housing part, at the edge of a first stepped rabbet is formed and with a second housing part, at the edge of a second stepped rabbet is formed.
  • the first stepped rebate and the second stepped rebate are formed complementary to each other, so that the first housing part and the second housing part can be assembled in an assembly direction.
  • Such hand tool machines are basically known from the prior art and are used in hand power tools such as combi hammers or hammer drills.
  • a portable power tool housing of the type mentioned above in that at the edge of the first housing part a groove and at the edge of the second housing part, a spring is formed, which form a transversely to the direction of interlocking positive tongue and groove connection.
  • the tongue and groove connection is positively connected perpendicular to the composition direction and / or in the longitudinal direction of extension of the edge.
  • the invention includes the realization that hand tool housing are typically made of plastic, in particular by injection molding, which can cause distortion and shrinkage of the housing parts. As a result, the housing parts of the portable power tool housing may not be dimensionally stable.
  • the invention also includes the recognition that, in prior art portable power tool housings, a first shifter and second shifter shifter connection typically needs to be stabilized by internal reinforcing struts and / or reinforcing webs.
  • the disadvantage here is, on the one hand, that there is an accumulation of material in the area of the stepped rebate pairing, which leads to sink marks, for example, leaks on the outside of the handheld power tool housing.
  • the reinforcing struts or reinforcing webs typical in the prior art have a low strength, since they are typically made very thin for reasons of material parsimony become.
  • said reinforcing struts or reinforcing webs cause a disturbing geometry which adversely affects a ventilation flow of a cooling fan provided by generating unwanted air turbulence.
  • a tongue and groove connection is provided which makes it possible to dispense with the reinforcing struts and reinforcing webs just described, i. saves material and at the same time is particularly stable.
  • the groove is provided on the longer in the assembly direction portion of the first stepped rabbet.
  • the spring may be provided on the shorter in the direction of assembly portion of the stepped rebate. It has proven to be advantageous if the groove and the spring are arranged on the respective edges of the housing parts, that they are not visible from outside the housing when the first housing part and the second housing part are assembled.
  • the groove, together with the longer portion of the first stepped rebate, can form a first minor stepped rebate.
  • the spring may form a second secondary stage fold together with a longer portion of the second stage rabbet in the assembly direction.
  • the first Maustichnfalz and the second Maumenfalz are formed complementary to each other. Such results in a particularly advantageous cohesion of the first and second housing part in the assembled state.
  • the groove and / or the spring has a height-to-width ratio between 1: 1 and 1: 3.
  • a height-to-width ratio is preferably about 1: 2.
  • a height is to be understood to mean an extension of the groove and / or the spring parallel to the composition direction.
  • a width is to be understood to mean an extension of the groove and / or the spring transversely to the composition direction, in particular perpendicular to the composition direction and in the longitudinal extension direction of the edge.
  • the groove and / or the spring has a height of about 2 mm and a width of about 5 mm.
  • the spring has rounded or chamfered corners to facilitate insertion of the spring into the groove in the course of assembling the first and second housing parts.
  • the height of the groove and / or the height of the spring is greater than the rebate height of the first and / or second devisnfalzes in the assembly direction.
  • the first Maustichnfalz preferably in the assembly direction, a greater FalzHAN than the first stepped rabbet and / or the second Maustimenfalz, preferably in the assembly direction, a greater rebate height than the second stepped rabbet.
  • At least one further tongue and groove connection is formed on the edge of the first housing part and on the edge of the second housing part.
  • the further tongue and groove connection or the further tongue and groove connections are spaced from the first tongue and groove connection along the edges.
  • the first shiplap and the second shiplap can be designed such that they form their own tongue and groove connection.
  • first housing part and / or the second housing part is free of reinforcing struts and / or reinforcing webs, preferably free of those of a surface of the first housing part and / or the second housing part, the surface normal transverse to the composition direction is oriented, protrude and / or protrude freely over the edges.
  • the portable power tool housing is preferably made of plastic, and may be manufactured by injection molding.
  • the first housing part is an upper housing part and the second housing part is a lower housing part.
  • the hand tool housing is preferably comprised of a hand tool.
  • a hand tool housing 100 is fragmentary in Fig. 1 shown.
  • the portable power tool housing 100 has a first housing part 10 and a second housing part 20.
  • the first housing part 10 is a housing upper part and the second housing part 20 is a housing lower part.
  • the first housing part 10 has an edge 11, which is oriented downwards in the illustrated embodiment.
  • a stepped fold 13 is formed at the edge 11 of the first housing part 10 .
  • a second stepped fold 23 is formed.
  • the edge 21 of the second devisnfalzes 23 is oriented in the illustrated embodiment, upwards.
  • the first stepped fold 13 and the second stepped fold 23 are formed complementary to each other. In this way, the first housing part 10 and the second housing part 20 can be assembled in a composition direction Z.
  • a groove 15 is formed at the edge 11 of the first housing part 10.
  • a spring 25 is formed at the edge 21 of the second housing part 20, a spring 25 is formed.
  • Groove 15 and spring 25 form a tongue and groove connection.
  • the tongue and groove connection 15, 25 is transversely to the direction of composition Z positively.
  • the transverse direction Q which is characterized by the directional arrow, is in the present case oriented perpendicular to the composition direction Z. In other words, the first housing part 10 and the second housing part 20 when they are assembled, not in the transverse direction Q against each other movable.
  • the height H of the groove 15 and the spring 25 are greater than the rebate height F of the first stepped rebate 13 and the second stepped rebate 23 in the assembly direction Z.
  • the groove 15 is provided on the longer in the direction of assembly Z section 17 of the first devisnfalzes 13.
  • the shorter section 18 of the first stepped fold 13 lying next to the longer section 17 is free of a groove.
  • the spring 25 is provided on the shorter in the direction of assembly Z section 28 of the second devisnfalzes 23. More specifically, the spring 25 is formed in the present embodiment illustrated on the shorter portion 28 of the second stepped rabbet 23.
  • the longer portion 27 of the second stepped rebate 23 remains in the assembly direction Z free of a spring.
  • the groove 15, together with the longer portion 17 of the first devisnfalzes 13 a first Maustinum 19.
  • the spring 25 forms a second Maustinumnfalz 29 together with a longer in the assembly direction Z longer portion 27 of the second devisnfalzes 23.
  • the first Maustinumnfalz 19 and the second Maumenfalz 29th are complementary to each other, which leads to a particularly secure cohesion of the first housing part 10 and the second housing part 20.
  • the groove 15 and the spring 25 a height-width ratio of about 1: 1, wherein the reference H denotes the parallel to the composition direction Z oriented height of the groove 15 and the spring 25 and wherein the reference B is perpendicular to Composition direction Z oriented width B of the groove 15 and the spring 25 respectively.
  • a surface OF of the first housing part 10 and the second housing part 20, which is directed in the assembled state of the power tool housing 100 in the direction of the housing inner side, is also in Fig. 1 designated.
  • the groove 15 and the spring 25 are thus arranged on the respective edges 11, 21, that they are not visible from outside the portable power tool housing 100, ie in the present case from behind, when the first housing part 10 and the second housing part 20 are assembled.
  • Fig. 2 shows a plan view of the in Fig. 1 illustrated second (lower) housing part 20. Perpendicular to the transverse direction Q is a section line A - A, which extends through the spring 25 shown. A section line B - B passes through a portion of the second housing part 20, which is free of a spring. Again Fig. 2 can be removed, the shorter portion 28 of the second devisnfalzes 23 is equipped with the spring 25, whereas the longer portion 27 of the second devisnfalzes 23 remains without spring.
  • the second Crowstich 29 is formed between the spring 25 and in the assembly direction Z (shown by an arrow pointing in the plane of the paper) longer portion 27 of the second stepped fold 23.
  • Fig. 3 is now the section A - A of the second (lower) housing part 20 of the Fig. 2 shown. Again Fig. 3 can be removed, the second Maustinumnfalz 29 is formed identically with respect to groove 25 and longer portion 27.
  • Fig. 4 shows a sectional view B - B of the second housing part 20 according to the in Fig. 2 drawn cut line B - B.
  • the second stepped rebate 23 starts from the surface OF, which is oriented to the interior of the housing.
  • the width of the longer portion 27 and the shorter portion 28 of the second stepped rabbet 23 are approximately the same width in the illustrated embodiment.
  • the spring 25 extends over the entire width of the shorter portion 28 of the second Maustichnfalzes 23rd
  • both the first housing part 10 and the second housing part 20 are free of Reinforcement struts and reinforcing webs, which protrude from the surface OF of the first housing part 10 and the second housing part 20. This applies both in the direction of the surface normal of the surface OF perpendicular to the composition direction Z and in terms of an outward projection over the edges 11, 21 parallel to the composition direction Z. This applies, of course, with the exception of the spring 25 according to the invention.
