Definitions

  • the invention relates to a handle of a machine tool according to the preamble of claim 1.
  • a handle which is composed of two housing shells. He has a shell element on which a resilient tongue is formed with latching hook. The shell element is attached via the latching hook to a projection on a handle. A release of the shell element from the handle can be made possible via an opening in the handle housing by unlocking the tongue from the projection. The possibility of closing the opening is not provided here.
  • the handle has a handle member.
  • the grip element comprises a rigid base body and a covering covering the base body of a Soft component.
  • the soft component which may be formed for example of rubber, is sprayed onto the rigid body.
  • the invention relates to a handle of a machine tool, in particular a hand-held machine tool, with a handle element which is fastened by means of at least one locking element on the handle, wherein the locking element in the locked state of the handle member on the handle via a means formed by an opening operable and in his Release position can be brought.
  • the grip element attached to the handle can be quickly and easily detached from the handle nondestructive.
  • damaging a housing of the machine tool upon release of the handle member from the handle e.g. by levering with a screwdriver, or damaging the locking element can be advantageously avoided.
  • the grip element can advantageously be exchanged and reused. It can thus be used, for example, different damping behavior, depending on the use of the machine tool, grip elements.
  • the means is formed by an opening.
  • the locking element can be structurally simple, for example in the housing of the machine tool, be arranged and operated through the opening of the machine tool.
  • the locking element can advantageously be protected against damage during operation or transport of the machine tool and the function of the locking element can be guaranteed.
  • the opening may be provided specifically for the locking element. However, it can also find an opening as a means application, which is already provided on the power tool. An attachment of an additional opening for operating the closure element can thus be advantageously avoided.
  • the opening is closed by a closure element during operation of the machine tool.
  • the locking element can be particularly easily protected against contamination by abrasion, such. Drilling dust, grinding dust, etc., protected and the function of the locking element can be ensured.
  • the closure element can in this case by a separate component, such. from an adhesive strip, a separate tab, etc., or from an existing component of the machine tool, in particular the hand tool, be formed.
  • the closure element is an energy supply unit of the machine tool.
  • the closure element is thus formed by an already existing component of the machine tool, and it can be ensured that the opening is always closed during operation of the machine tool. If the power supply unit is designed such that it closes an opening which at least partially accommodates the power supply in the operating state of the machine tool, then this opening can be used as a means for operating the locking element. It is thus achievable means over which the locking element is easy and comfortable to use. In addition, a trained as a closure element power supply unit of Handle are removed to operate the locking element and thus to release the handle element from the handle.
  • the machine tool can not be operated when the power supply unit is removed, the work safety is increased in this way, since unintentional starting of the machine tool during the operation of the locking elements can be effectively avoided.
  • This is particularly advantageous if the handle element in the mounted state on the handle an opening in the housing of the machine tool, in particular a service opening, covered. With uncovered opening, the machine tool can not start.
  • a structurally simple locking element can be achieved by the locking element formed as a locking element and the handle element latching on the handle is fastened. Additional loose components, such as screws, etc., are advantageously avoidable.
  • the locking element can by an elastically deformable latching element, by a movable against a spring element latching element or by another, the expert appears reasonable as a detent element be formed. If the latching element is elastically deformable, the latching element can be made in one piece with the handle or with the gripping element and molded onto it in an injection molding process or another process that appears appropriate to a person skilled in the art. Costs, in particular production and assembly costs, as well as installation costs can be reduced.
  • an unlocking element is proposed, with which the locking element is operable.
  • the locking element can by the operator can be easily brought over the Entriegelüngselement in its release position, whereby a great comfort for the operator can be achieved.
  • the unlocking element may be attached to an outside of the housing and / or arranged in the housing of the machine tool.
  • the unlocking element can in this case, for example, a part of the handle member, a key located on the housing, a rod which secures the locking element form-fitting form, or it can be configured in another, the skilled person appear useful form.
  • the locking element is about the separate tool, in particular screwdriver, pens, etc., which are always available to the operator, brought into its release position.
  • the locking element has an actuating region, via which the locking element can be operated.
  • the operator can bring the unlocking tool over the operating area with the locking element positively and / or non-positively in abutment and move the locking element in its release position.
  • Fig. 1 shows a portion of a battery-powered angle grinder 10 with a housing 24 having two half-shells 26, 28 made of plastic.
  • the housing 24 is connected at its first end with a non-illustrated gear made of metal gearbox of the angle grinder 10 and has at its second end a receiving area 54 for an unspecified, formed by a battery pack power supply unit.
  • the receiving area 54 for the power supply unit comprises an opening 20 in the housing 24.
  • the power supply unit is inserted into the opening 20 and fastened there. This engage locking elements of the power supply unit in corresponding recesses 48, 50 which are integrally formed on the housing 24 of the angle grinder 10.
  • the opening 20 is closed by the power supply unit, which thus forms a closure element for the opening 20.
  • the housing 24 of the angle grinder 10 comprises a handle 18 with a gripping element 12.
  • the gripping element 12 comprises a rigid base body 30 onto which a soft component of thermoplastic elastomers (TPE) is directly injected.
  • TPE thermoplastic elastomers
  • the grip element 12 or the base body 30 has locking elements 14, 16, 32 and a plug-in element 34 on its side facing the housing 24, which are molded onto the base body 30 in an injection molding process.
  • the locking elements 14, 16, 32 extend perpendicular to the longitudinal extent 52 of the housing 24, while the plug element 34 extends in the longitudinal extent 52 of the housing 24 in the direction of the transmission housing.
  • corresponding elements 36 are integrally formed on a respective half shell 26, 28 in a part of the handle 18 facing the receiving region 54 to form the locking elements 14, 16.
  • the latching elements formed by locking elements 14, 16 When mounted in the handle 18 grip element 12, the latching elements formed by locking elements 14, 16 in the locked state and engage behind their locking surfaces 40, 42 positively locking surfaces 38 of the corresponding elements 36.
  • the handle member 12 is latchingly attached to the handle 18.
  • the locking elements 14, 16 In order to bring the locking elements 14, 16 in their release position, the locking elements 14, 16 are can be operated via the opening 20.
  • the power supply unit is removed and the opening 20 is released.
  • the locking elements 14, 16 are now on their actuation surfaces 44, 46 operable by the operator with a separate unlocking element 22 and brought into its release position.
  • the unlocking element 22 is in this case formed by a screwdriver.
