Definitions

  • the invention relates to a housing for a hand-held tool according to the preamble of claim 1.
  • a hand-held tool with two housing halves is known.
  • One housing half has a rib on its outer wall which is introduced into a groove in the outer wall of the other housing half by means of a press fit. This creates a separation resistance between the two housing halves.
  • Such housings can be damaged in particular when falling from waist height.
  • the invention is based on the object of developing a generic housing in such a way that it is of stable design.
  • the first rib protrudes beyond the parting plane into the second housing shell.
  • the parting plane there are numerous first measuring points from which the second shell height can be determined.
  • first measuring points exist in the parting plane, at which the first rib height is at least 30%, in particular at least 45%, preferably at least 60% of the second shell height.
  • the second housing shell expediently has a second rib which extends in the transverse direction and protrudes beyond the parting plane into the first housing shell.
  • the second rib has a second rib height measured in the transverse direction starting from a second measuring point in the parting plane up to a second end of the second rib facing the first housing shell.
  • the first housing shell has a first shell height measured in the transverse direction starting from the same second measuring point of the parting plane up to a first inside of the first housing shell facing the second housing shell.
  • At least one second measuring point advantageously exists in the parting plane, at which the second rib height is at least 30%, in particular at least 45%, preferably at least 60% of the first shell height.
  • the first rib has a first maximum wall thickness measured perpendicular to the transverse direction in a wall thickness direction.
  • a rib spacing measured in the direction of the wall thickness between the first rib and the second rib is advantageously less than the first maximum wall thickness, in particular less than two thirds of the first maximum wall thickness.
  • the housing is stiffened in the area in which the rib spacing is less than the first maximum wall thickness, in particular less than two thirds of the first maximum wall thickness.
  • the stiffening is achieved through the interaction of the first and the second rib.
  • Thicker ribs in only one housing shell would also lead to greater stiffening.
  • thicker ribs would have the further disadvantage that visually unsightly sink marks can occur opposite the bottom of the rib on the outside of the first housing wall. This can be avoided when the housing is reinforced by first and second ribs with a rib spacing of less than the first maximum wall thickness, in particular less than two thirds of the first maximum wall thickness. The result is an attractive visual design with high stability and strength of the housing at the same time.
  • a stiffening by the rib spacing of less than the first maximum wall thickness, in particular less than two thirds of the first maximum wall thickness can be achieved in a simple manner, in particular in comparison to the use of a separate stiffening component that is inserted between the two housing shells.
  • the rib spacing is advantageously at least 1%, in particular at least 5% of the first maximum wall thickness. This ensures that in the event of an external deformation of the housing, for example during an impact, the first rib and the second rib come to rest against one another and energy can be transferred from one rib to the other.
  • the rib spacing is expediently essentially constant.
  • a wall thickness of the first rib measured in the direction of the wall thickness advantageously deviates in the transverse direction by less than 10% from the first maximum wall thickness.
  • the first rib extends on both sides of the parting plane.
  • the first rib has at least one first region which is arranged at a first distance from the second outer wall, measured in the parting plane perpendicular to the second outer wall. This also increases the stability of the housing in the area spaced apart from the outer wall.
  • the first rib is expediently fixed on the first outer wall.
  • the first rib is fixed in the transverse direction with its first rib base on the first outer wall.
  • the first rib is made of the same material as the first outer wall. This creates a stable connection between the first rib and the first outer wall.
  • the first rib has a first shell distance measured in the transverse direction from the second housing shell and that the first shell distance is greater than 40% of the first maximum wall thickness of the first rib.
  • the housing can be designed in such a way that the first rib and the second rib overlap over a large area with respect to the transverse direction.
  • the first rib is supported close to a second rib base of the second rib, so that forces can be absorbed and passed on well.
  • the first housing shell has at least two first ribs.
  • the at least two first ribs expediently have a point of intersection, seen in the transverse direction. The crossing of the first ribs creates a stable structure that increases the stability of the housing.
  • the intersection point has a first cross spacing from the first housing wall.
  • the at least two first ribs expediently extend, viewed in the transverse direction, starting from the intersection point as far as the first housing wall.
  • forces can be transmitted between the point of intersection and the first housing wall.
  • the at least two first ribs can help absorb forces via the intersection point. As a result, forces are distributed more evenly and can be absorbed more easily by the housing without damage.
  • the first housing shell expediently has several first ribs.
  • the second housing shell has a plurality of second ribs.
  • the plurality of first ribs and the plurality of second ribs have a total length measured in the parting plane.
  • the plurality of first ribs and the plurality of second ribs are delimited in the parting plane by an enveloping polygon.
  • the corner points of the polygon lie on the end points of the several first ribs and the plurality of second ribs in the parting plane.
  • the polygon has a polygonal area.
  • the quotient of the total length of the multiple first ribs and the multiple second ribs and the polygonal area is at least 0.2 mm ⁇ 1 . This results in a sufficiently large rib density for a high stability of the housing.
  • the first rib expediently has a first recess.
  • the second housing shell has a second reinforcing rib.
  • the second reinforcement rib extends from the second housing wall in the transverse direction in the direction of the first housing shell.
  • the second reinforcement rib extends exclusively on one side of the parting plane.
  • the second reinforcement rib is a second rib of the second housing shell and protrudes beyond the parting plane into the first housing shell.
  • the second reinforcing rib advantageously protrudes in the transverse direction into the first recess of the first rib.
  • the second reinforcement rib crosses the recess of the first rib in the direction perpendicular to the transverse direction. If the housing is deformed, the first rib of the first housing shell and the second reinforcing rib of the second housing shell can be supported on one another, and forces can be transmitted between them. This also increases the stability.
  • the plurality of first ribs viewed in the transverse direction, form a structure that encircles the transverse direction in a closed manner. Due to the closed structure, the plurality of first ribs of the second part of the plurality of first ribs can transmit forces to one another. This increases the stability of the housing.
  • the first housing shell and the second housing shell are expediently injection molded parts.
  • the housing is a handle housing.
  • An operating element for operating the implement is expediently arranged on the handle housing.
  • the first rib intersects the parting plane over a summed up first length and that the first rib has first measuring points over at least half of the summed up first length at which the first rib height is at least 30%, in particular at least 45%. , preferably at least 60% of the assigned second shell height.
  • the rib spacing between the first rib of the first housing shell and the second rib of the second housing shell over at least half the sum of the first length of the first rib is less than the first maximum wall thickness of the first rib, in particular less than two thirds of the first maximum Wall thickness of the first rib is.
  • the second rib intersects the parting plane over a summed up second length and that the second rib has first measuring points over at least half of the summed up second length, at which the second rib height is at least 30%, in particular at least 45%, preferably at least 60% of the assigned second shell height is.
