Definitions

• the invention relates to a handle of a machine tool according to the preamble of claim 1.
• a machine tool is known from the document DE 199 18 118 AI, the handle of which has a grip element.
• the grip element comprises a rigid base body and a covering of a soft component covering the base body.
• the soft component which can be made of rubber, for example, is sprayed onto the rigid base body.
• the grip element is fastened to the handle via a plug-in element which is positively inserted into a recess on the handle and via a locking element which snaps onto the housing.
• the invention is based on a handle of a machine tool, in particular a hand-held machine tool, with a handle element that can be attached to the handle using at least one locking element.
• the locking element in the locked state of the handle element on the handle can be operated via a means and brought into its release position.
• the handle element attached to the handle can be quickly and easily removed from the handle without being destroyed.
• damage to a housing of the machine tool when releasing the handle 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.
• handle elements with, for example, different damping behavior can thus be used.
• a structurally simple locking element can be achieved in that the locking element is designed as a latching element and the handle element can be latched to the handle. Additional components that can be lost, such as screws, etc., can advantageously be avoided.
• the locking element can be of an elastically deformable locking element, of a locking element that can be moved against a spring element, or of another locking element that appears useful to a person skilled in the art be educated. If the latching element is elastically deformable, the latching element can be made in one piece with the handle or with the handle element and molded onto it in an injection molding process or in another process which seems sensible to a person skilled in the art. Costs, in particular production and assembly costs, as well as assembly costs can be reduced.
• the means is formed by an opening.
• the locking element can be arranged in a structurally simple manner, for example in the housing of the machine tool, and can be operated through the opening of the machine tool.
• the locking element can advantageously be protected from damage during operation or transportation of the machine tool and the function of the locking element can be ensured.
• the opening can be provided specifically for the locking element.
• an opening can also be used as a means that is already provided on the handheld power tool. An attachment of an additional opening for operating the closure element can thus advantageously be avoided.
• the opening is particularly advantageously closed by a closure element during operation of the machine tool.
• the locking element can be protected particularly easily against contamination by abrasion, such as drilling dust, grinding dust, etc., and the function of the locking element can be guaranteed.
• the closure element can be a separate component, such as an adhesive strip, a separate tab, etc., or a pre- existing component of the machine tool, in particular the handheld power tool, be formed.
• the closure element is advantageously a power 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 energy supply unit is designed in such a way that, when the machine tool is in the operating state, it closes an opening that at least partially receives the energy supply, this opening can be used as a means for operating the locking element. A means can thus be reached via which the locking element can be operated easily and comfortably.
• a power supply unit designed as a closure element must be removed from the handle in order to operate the locking element and thus to release the handle element from the handle.
• the machine tool cannot be operated when the power supply unit is removed, occupational safety is increased in this way, since unintentional starting of the machine tool when operating the locking elements can be effectively avoided.
• the grip element when mounted on the handle, covers an opening in the machine tool housing, in particular a service opening. The machine tool cannot start if the opening is not covered.
• an unlocking element is proposed with which the locking element can be operated.
• the locking element can be can simply be brought into its release position via the unlocking element, which means that great convenience for the operator can be achieved.
• the unlocking element can be attached to an outside of the housing and / or can be arranged in the housing of the machine tool.
• the unlocking element can, for example, form part of the grip element, a button located on the housing, a rod that secures the locking element in a form-fitting manner, or it can be designed in another form that appears useful to a person skilled in the art.
• the unlocking element is a separate tool, a structurally simple and robust locking element can be achieved which is inexpensive to manufacture.
• the locking element can be brought into its release position via the separate tool, such as, in particular, screwdrivers, pens, etc., which are always available to the operator.
• the locking element particularly advantageously has an actuation area, via which the locking element can be operated.
• the operator can bring the unlocking tool into positive and / or non-positive contact with the locking element via the actuation area and move the locking element into its release position.
• Fig. 1 shows a section of a battery-operated angle grinder with a handle element
• Fig. 2 shows an enlarged section of the handle element mounted on a handle with a locking element in the locked state.
• FIG. 1 shows a part of a battery-operated angle grinder 10 with a housing 24 which has two half-shells 26, 28 made of plastic.
• the housing 24 can be connected at its first end to a gear housing of the angle grinder 10, which is not shown in detail, and has at its second end a receiving area 54 for an energy supply unit, not shown, which is formed by a battery pack.
• the receiving area 54 for the energy supply unit comprises an opening 20 in the housing 24. To operate the hand power tool 10, the energy supply unit is pushed into the opening 20 and fastened there.
• locking elements of the energy Supply unit in corresponding recesses 48, 50 which are integrally formed on the housing 24 of the angle grinder 10.
• the housing 24 of the angle grinder 10 comprises a handle 18 with a handle element 12.
• the handle element 12 comprises a rigid base body 30, onto which a soft component made of thermoplastic elastomers (TPE) is sprayed directly.
• TPE thermoplastic elastomers
• the grip element 12 or the base body 30 has locking elements 14, 16, 32 and a plug 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 extension 52 of the housing 24, while the plug element 34 extends in the longitudinal extension 52 of the housing 24 in the direction of the gear housing.
• elements 36 corresponding to the locking elements 14, 16 are formed on a half-shell 26, 2-8 in a part of the handle 18 facing the receiving area 54.
• the locking elements 14, 16 formed by locking elements are in the locked state and engage with their locking surfaces 40, 42 in a form-fitting manner locking surfaces 38 of the corresponding elements 36.
• the locking elements 14, 16 can be operated via the opening 20.
• the energy supply unit is removed and the opening 20 is released.
• the locking elements 14, 16 can now be operated by the operator via their actuating surfaces 44, 46 with a separate unlocking element 22 and brought into their release position.
• the unlocking element 22 is expediently formed by a screwdriver.
