Hand-Held Power Tool Device, Hand-Held Power Tool having the Hand-Held Power Tool Device, and Accessories having the Hand-Held Power Tool Device

PRIOR ART

A hand-held power tool device for a hand-held power tool, in particular an angle grinder, has already been proposed, having at least one attachment hood for connection to a protective hood for at least partially covering a working tool of the hand-held power tool.

DISCLOSURE OF THE INVENTION

The invention is based on a hand-held power tool device for a hand-held power tool, in particular an angle grinder, having at least one attachment hood for connection to a protective hood for at least partially covering a working tool of the hand-held power tool.

It is proposed that the attachment hood has at least one positive connecting element which is provided to cooperate with a collar-like and free-standing outer region, running in a circumferential direction, of the protective hood and at least contribute to the connection.

Advantageously, an ease of use for a user may be improved by means of the design according to the invention of the hand-held power tool device. In particular, a particularly simple and/or rapid attachment of the attachment hood to the protective hood is permitted by connecting the attachment hood to the protective hood by means of the positive connecting element. Advantageously, a hand-held power tool device may also be provided with a high degree of functionality and flexibility. The protective hood may be used, on the one hand, without the attachment hood as a protective hood for roughing and/or grinding operations and may be additionally used in conjunction with the attachment hood as a detachable protective hood. Moreover, an occupational safety for a user may be advantageously increased. In particular, advantageously a user may be motivated by the particularly simple and rapid connection to maintain occupational safety regulations for operations which require the use of a detachable protective hood. Moreover, production costs and also procurement costs may be advantageously reduced thereby for a user. In particular, a production of an attachment hood is more cost-effective than a production of a complete detachable protective hood which is configured in one piece. Moreover, the attachment hood is advantageously compatible with most common and commercially available protective hoods, so that by purchasing an accessory with a hand-held power tool device according to the invention, users may advantageously complement a protective hood for a hand-held power tool which is already in their possession with an attachment hood and use this in conjunction with the attachment hood as a detachable protective hood.

A “hand-held power tool device” may be understood to mean, in particular, a part, in particular a functional constituent part, in particular a structural and/or functional component, of a hand-held power tool or a part, in particular a functioning constituent part, in particular an additional functional component, of an accessory for a hand-held power tool.

For partially covering the working tool, the protective hood forms, in particular, at least one protective surface which in an operating state of the hand-held power tool at least covers a partial region of a first main surface of the working tool. In particular, the first main surface is a largest side surface of the working tool facing a drive unit of the hand-held power tool in the operating state of the hand-held power tool. A second main surface of the working tool may be arranged, in particular, without being covered by the protective hood in the operating state. In particular, the second main surface of the working tool is a largest side surface of the working tool which faces away from the drive unit of the hand-held power tool in the operating state and which, in particular, faces a workpiece to be machined in the operating state. The protective hood may be configured, in particular, as a protective hood for roughing and/or grinding operations, in particular for material-removing machining methods with large volumes of removed material being produced on the workpiece side.

The attachment hood is provided, in particular, for at least partially covering the second main surface of the working tool. The attachment hood is provided, in particular, in conjunction with the protective hood to form a detachable protective hood, in particular a detachable protective hood of the C-type according to the Standard EN 62841-2-3. “At least partially covering” is intended to be understood to mean, in particular, a covering of a partial region of an object which advantageously corresponds to at least 20%, advantageously at least 30%, particularly advantageously at least 40%, preferably at least 45%, and particularly preferably at least 50% of a total surface of the object.

An “outer region of the protective hood” is intended to be understood to mean, in particular, a region of the protective hood which comprises an external edge which defines an extent of the protective hood and which extends in the direction of the second main surface of the working tool.

“Provided” is intended to be understood to mean, in particular, specifically designed and/or specifically equipped. An object being provided for a specific function is intended to be understood to mean, in particular, that the object fulfils and/or performs this specific function in at least one use state and/or operating state.

It is further proposed that the attachment hood has at least one fixing unit for fixing an angular position of the attachment hood relative to the protective hood. Advantageously, a fixing of the connection of the attachment hood to the protective hood may be permitted thereby. The fixing by the fixing unit may be carried out positively and/or non-positively. For example, it might be conceivable that the fixing is provided by the fixing unit by means of a clamping connection and/or a latching connection and/or a tensioning connection and/or a screw connection and/or the like. Advantageously, the attachment hood and the protective hood have an extent which is at least substantially of the same size relative to a circumference of the working tool of the hand-held power tool. “At least substantially” in this context is intended to be understood to mean, in particular, that a deviation from a predetermined value deviates, in particular, by less than 25%, preferably by less than 10% and particularly preferably by less than 5% of the predetermined value. An “angular position” in this context is intended to be understood to mean, in particular, an angle of a circular sector of the working tool which is only at least partially covered by the protective hood in a state in which the attachment hood is connected to the protective hood and is fixed by means of the fixing unit. If a value of the angle of the angular position in which the attachment hood is fixed by means of the fixing unit relative to the protective hood is for example 0°, the protective hood and the attachment hood in each case at least partially cover the same circular sector of the working tool, wherein the protective hood at least partially covers the first main surface in the region of the circular sector and the attachment hood at least partially covers the second main surface of the working tool opposing the first main surface in the same region of the circular sector. If a value of the angle of the angular position in which the attachment hood is fixed by means of the fixing unit relative to the protective hood is for example 90°, the protective hood covers the first main surface of the working tool in region of a circular sector at an angle of 90°, whilst the second main surface of the working tool is not covered by the attachment hood in the region of this circular sector.

The fixing unit may be provided for fixing in exactly one specific angular position of the attachment hood relative to the protective hood. Advantageously, it is proposed that the fixing unit permits the fixing in an angular position between the attachment hood and the protective hood which is selectable by a user. Advantageously, a flexibility for a user may be improved thereby. The fixing unit could permit the fixing in different steps of angular positions which are selectable by the user. Preferably, the fixing unit permits a stepless adjustment of the fixing in an angular position which is freely selectable by the user.

It is additionally proposed that the fixing unit has at least one fixing element which is configured as a clamping lever. Advantageously, a particularly simple fixing of the attachment hood to the protective hood, in particular without the use of tools, may be permitted thereby. A “clamping lever” is intended to be understood to mean, in particular, an operating part which provides a tensioning force for fixing a first object to a second object. Preferably, a fixing may be produced by means of the clamping lever without the use of tools and may be released again without the use of tools. The clamping lever may be configured, in particular, as a tensioning lever and, in particular, have a tensioning hook or the like which for the fixing engages in a mating contour, for example a tab or a groove or an aperture or an edge, in particular an edge of the protective hood, and/or partially encompasses this edge and is braced with this mating contour. The clamping lever may be configured, in particular, as a tensioner, quick-release tensioner or eccentric lever. The clamping lever may have, in particular, a lever element which may be connected to a further element of the clamping lever, in particular a bolt or a resilient tensioning element and which may be braced by the lever element for the fixing.

Alternatively or additionally, it is proposed that the fixing unit has at last one fixing element which is configured as a clamping screw. Advantageously, a reliable fixing may be implemented thereby by simple technical means. Advantageously, the clamping screw forms at least one contact surface for the fixing. The clamping screw has at least one external thread. The external thread of the clamping screw may be configured to be fully threaded or partially threaded. The clamping screw may be configured in one piece, wherein the external thread of the clamping screw may be screwed, in particular, into a corresponding internal thread of the attachment hood for the fixing. In the case of a clamping screw configured in one piece, the contact surface may be configured, in particular, as a planar lower face of the clamping screw. Alternatively, the clamping screw may be configured in multiple parts, in particular in two parts.

The clamping screw which is configured in multiple parts may have, in particular, a cylindrical connecting element, for example a bolt, in particular a threaded bolt, and/or a threaded rod or the like which may have, in particular, the external thread, and may have at least one counter connecting element corresponding to the connecting element, for example a clamping nut and/or tensioning nut, which may have in particular an internal thread corresponding to the external thread of the connecting element, and/or a tensioning pin and/or a split pin and/or the like. In the case of a clamping screw configured in multiple parts the contact surface could be arranged, in particular, on the cylindrical connecting element and could be configured, in particular, in one piece therewith. Alternatively or additionally, it might be conceivable that the contact surface is configured as a washer and/or as a rubber pad or the like.

Alternatively or additionally, it is further proposed that the fixing unit has at least one fixing element which is configured as a stop element. Advantageously, a particularly simple and releasable fixing which may be produced, in particular, without the use of tools may be permitted thereby. The stop element may be configured, for example, as a grip element and, for the fixing, provided to encompass a partial region of the protective hood, in particular the outer region of the protective hood, in particular positively. Alternatively or additionally, the stop element could be configured as a latching element, for example as a latching cam or the like and, for the fixing, provided to be latched to a counter latching element arranged on the protective hood, for example a latching groove or a latching opening or the like, and/or to an external edge of the protective hood.

Alternatively or additionally, it is further proposed that the fixing unit has at least one fixing element which is configured as a wedge element. Advantageously, a particularly simple and releasable fixing, in particular which may be produced without the use of tools, may be permitted thereby. In particular, a simple release of the fixing is permitted, even in the case of significant contamination in the region of the fixing unit which, for example, may be caused by cooled sparks or the like. A “wedge element” is intended to be understood to mean, in particular, an element with at least two tapering side surfaces which form at least one wedge surface which cooperate for the fixing with at least one further surface, in particular a surface of the protective hood and/or the positive connecting element and which permit the fixing to be maintained by means of a force, in particular a frictional force.

It is further proposed that the positive connecting element is configured as an annular holding element. Advantageously, a particularly reliable positive connection may be achieved thereby. By the holding element being “annular” is intended to be understood to mean in this context, in particular, that a largest extent of the holding element has a shape of a circular segment at least in a state of a positive connection with the outer region of the protective hood. The annular holding element may extend, in particular, along a total circumferential extent of the collar-like and free-standing outer region of the protective hood. Alternatively, it is conceivable that the annular partial element extends over a partial circumference of the collar-like and free-standing outer region of the protective hood. The annular partial element could be configured, for example, as a rigid element, the main extent thereof substantially corresponding to the circumferential extent or a partial region of the circumferential extent of the collar-like and free-standing outer region of the protective hood. Preferably, the annular holding element is configured as a resilient element and is produced from a resilient material, for example from a plastics from the group of elastomers. A “resilient element” is intended to be understood to mean, in particular, an element which may be repeatedly deformed without the element being mechanically damaged or destroyed thereby and which, in particular after a deformation, automatically strives to return to an original shape.

It is further proposed that the attachment hood has at least one protective element for protecting the outer region of the protective hood from damage. Advantageously, by simple technical means the outer region of the protective hood may be protected thereby from damage, for example from scratching or the like. The protective element may have, for example, a textile woven fabric, for example felt or the like and/or be configured therefrom. Alternatively or additionally, it is conceivable that the protective element is configured as a resilient element, for example as a rubber lip or the like. It is also conceivable that the positive connecting element, in particular the positive connecting element configured as an annular holding element, functions at the same time as the protective element for protecting the outer region of the protective hood from damage.

It is further proposed that the attachment hood comprises a first attachment hood element and a second attachment hood element which may be positively connected to the first attachment hood element. Advantageously, a flexibility for a user may be increased thereby. The first attachment hood element may have, in particular, the positive connecting element and, in particular, may be connected to the protective hood without the second attachment hood element. It is conceivable, for example, that the first attachment hood element has a first protective function of the attachment hood, for example a covering of a first partial region of the working tool of the hand-held power tool, and the second attachment hood element has a second protective function of the attachment hood, in particular complementing the first protective function, for example a covering of a second partial region of the working tool of the hand-held power tool. For example, the first attachment hood element and the second attachment hood element could be positively connectable together so as to be offset relative to one another in an angular range. As a result, advantageously a particularly large region of a circular sector of the second main surface of the working tool may be covered by the covering cover. The first attachment hood element and the second attachment hood element could cooperate for the connection to the protective hood and, in particular, form a common positive connecting element. For example, it is conceivable that the first attachment hood element cooperates with a first side of the outer region of the protective hood and the second attachment hood element cooperates with a second side of the outer region. It is conceivable, in particular, that regions of the first attachment hood element and the second attachment hood element form the fixing unit and that a fixing of the attachment hood relative to the protective hood is permitted without further fixing elements. For example, the first attachment hood element could have a first geometry, for example in the form of a latching cam, which for the fixing engages in a second geometry of the second attachment hood element, for example a latching recess.

It is further proposed that the fixing unit is arranged between the first attachment hood element and the second attachment hood element.

As a result, by means of the fixing unit, in addition to the fixing of the attachment hood in the angular position relative to the protective hood, at the same time advantageously the positive connection may be fixed between the first attachment hood element and the second attachment hood element. Preferably, a fixing element of the fixing unit arranged between the first attachment hood element and the second attachment hood element is configured as a wedge element. The second attachment hood element may have an aperture through which the fixing unit may be actuated.

In this case, the hand-held power tool device according to the invention is not intended to be limited to the above-described use and embodiment. In particular, the hand-held power tool device according to the invention may have a number of individual elements, components and units which differs from a number cited herein for fulfilling a mode of operation described herein. In the case of value ranges specified in this disclosure, values lying within the aforementioned limits are also intended to be regarded as disclosed and are able to be used in any manner.
