Description

Arbeitsvorrichtung, insbesondere zur Verwendung im Haushalt, Garten und/oder zur gewerblichen NutzungWorking device, in particular for use in the home, garden and / or commercial use

The invention relates to a working device, in particular for use in the home, garden and / or commercial use, for example in industry, the craft and / or in the service industry, with a handle, with a tool for cleaning, cleaning or processing a floor and with a connecting device for (preferably releasable) connection of a tool-side connecting portion with a handle-side connecting portion.

From DE 198 27 061 A1 a working device is known which makes it possible to releasably connect a handle with different tools, for example a snow shovel, a broom, a shovel or the like. Such a working device has the advantage that only one handle must be kept ready, which can be used for a variety of tools.

The present invention has for its object to provide a working device which allows a particularly variable and efficient use of a tool.

This object is achieved in that at least one tool-side connecting portion is provided on the tool, which is aligned relative to the tool or alignable such that a longitudinal axis of the stem relative to a reference plane, which an active edge and / or an effective surface of the tool in Operating position of the tool in the vertical direction interspersed, inclined aligned or can be aligned.

The working device according to the invention makes it possible to connect a tool and a handle together so that the handle is inclined starting from the conventionally known straight orientation. This inclination makes it possible to operate the working device by gripping the handle in a conventional manner, wherein the effective edge and / or the effective surface of the tool of the inclination of the stem axis is inclined to the reference plane accordingly.

The effective edge of the tool is, for example, the lower edge of a snow shovel which, in the position of use of the snow shovel, rests on a surface to be cleared of snow. The active surface is, for example, a blade surface of the snow pusher. Due to the inclination of the stem axis of the stem can be handled in a conventional manner "in a straight line" (ie within the reference plane), while at least the effective edge of the tool and preferably the entire tool has a corresponding lateral inclination. This makes it possible to push snow or dirt or water, not only in the reference plane corresponding straight direction in front of him, but to push snow, dirt, water or the like during the forward sliding movement at the same time laterally outward. This eliminates a tedious and labor-intensive "reconnecting" the working device in which to be cleared snow, dirt, water or the like can be spent only in batches laterally. The working device according to the invention enables a continuous, continuous and thus more comfortable and much more efficient handling of the tool.

Corresponding advantages arise for the handling of a rake, which is guided with a backward movement. Due to the inclination of the stem when retraction of the rake in the direction of an operator, the debris, ie leaves, for example, not only swept in the direction of the operator, but at the same time be transported laterally.

It is preferred if a plurality of tool-side connecting sections are provided on the tool. This makes it possible to selectively connect the handle or its handle-side connecting portion with one of the tool-side held connecting portions. In this way, the inclination of the effective edge of the tool can be adjusted in a simple manner by selecting a suitably inclined tool-side connecting portion.

It is preferred if the connecting sections are arranged symmetrically with respect to the reference plane, so that identical tilt angles are adjustable on the left and right sides.

In a further preferred embodiment, at least one tool-side connecting portion is provided, the orientation of which is adjustable relative to the tool by means of an adjusting device. It is preferred if the adjustment range of the adjustment device allows an orientation of the tool-side connection portion inclined both within the reference plane and on both sides relative to the reference plane.

A particularly simple adjusting device can be created if it comprises a tool-side connecting section which can be pivoted about a pivot axis. This allows adjustment of the inclination angle by simply pivoting the tool-side connecting portion about the pivot axis.

Furthermore, it is preferred if the setting device comprises a fixing device for fixing the tool-side connecting portion in a desired pivot position, so that the tool or its effective edge can be held in a desired inclination.

A particularly simple operation of the fixing results when the fixing device comprises a clamping screw, which in particular is operated without tools.

In a further embodiment of the invention, at least one tool-side connecting portion is provided, which is aligned or orientable relative to the tool such that when connected to the handle-side connecting portion, the longitudinal axis of the handle extends within the reference plane. This makes it possible to use the working device in a conventional manner, so without a good to be swept away at the same time transported laterally.

In a further embodiment of the invention a spaced apart from a pivot axis of the handle attachment means is provided, which enables a stable fixation of the stem to the tool.

A particularly easy-to-handle fastening device is obtained if this is designed in the form of a hand-operated clamping device.

Preferably, the stem is pivotable about a pivot axis, in particular continuously, so that there is a particularly easy adjustability of a pivotal position of the stem.

The tool of the working device according to the invention is preferably a blade, in particular a snow shovel, or a shovel, a slider, a broom or a rake.

The invention further relates to a tool, in particular a tool mentioned above, for a working device described above.

Fig. 13 is a side view corresponding to FIG. 12 in a movable relative to the tool of the working device state of the stem.

In Figure 1, an embodiment of a working device is generally designated by the reference numeral 10. The working device 10 comprises a tool 12 which is connectable to a stem 16 extending along a stem 16.

The tool 12 is formed in the example shown in Figure 1 in the form of a blade 18, in particular in the form of a snow shovel.

The tool 18 has an operative edge 22 which rests on a base 20 to be processed in the position of use of the tool 12 and which delimits an active surface 23 in the form of a blade surface. The active edge 22 may be formed for example by a boundary of the active surface 23 or by a bottom edge of the blade 18 comprehensive metal edge 24.

To connect the handle 16 and the tool 12, a connecting device designated overall by the reference numeral 26 is provided. The connecting device comprises a handle-side connecting portion 28, which is formed by an end portion of the handle 16 facing the tool 12.

The connecting device 26 further comprises one or more tool-side connecting portions.

A relative to the tool 12 centrally arranged tool-side connecting portion is designated by the reference numeral 30. The connecting portion 30 is preferably in the form of a fixedly connected to the tool 12 (ie, for example, with the blade 18) connected to sleeve 32, in which the handle-side connecting portion 28 is pluggable receiving. The securing of the handle-side connecting portion 28 on or in the tool-side connecting portion 30 can be effected, for example, by a clamping action between the outer surface of the end portion of the stem 16 and the inner surface of the sleeve 32 and / or by additional securing elements, for example by screws or bolts.

The connecting portion 30 is arranged on the tool 12 and aligned relative thereto, that the stem axis 14 is within a plane 34 which is oriented vertically in the working or use position of the tool 12 and the active edge 22 and the active surface 23 in the vertical direction interspersed. Therefore, when using the tool-side connecting portion 30, the working device 10 can be used in a conventional manner, so for example, with the help of the blade 18 snow are pushed forward in a straight direction.

The working device 10 has at least one further tool-

side connecting portion

36, 38. These are also fixedly connected to the tool 12, but are inclined relative to the plane 34 (and relative to the tool-side connecting portion 30). This makes it possible to connect the handle 16 to one of the tool-

side connecting sections

36 or 38 as an alternative to a connection with the tool-side connecting section 30. If the handle 16 is connected to the tool-side connecting portion 36 and the handle 16 moves in use of the working device 10 in a conventional manner within the plane 34 forward, the active edge 22 is inclined from its basic position to the right, so that upon a forward movement of the working device 10 a goods to be swept (for example, snow) not only forward, but at the same time pushed to the right.

In a corresponding manner, the tool 12 can be aligned with the use of the tool-side connecting portion 38 relative to a forward sliding movement to the left inclined.

FIG. 2 shows a tool 12 in the form of a slide 40, in particular in the form of a water slide 44. This tool 12 also has a plurality of tool-

side connecting portions

30, 36, 38 for connection to a handle 16. The adjustable by the different orientation of the said tool-side connecting

portions inclination angle

42 and 44 are preferably identical, for example, between about 10 ° and about 50 °.

FIG. 3 shows a tool 12 on which a tool-side connecting section 46 is pivotably mounted about a pivot axis 48. Based on the reference plane 34, in which the tool-side connecting portion 46 assumes a straight basic position, the tool-side connecting portion 46 can be pivoted in mutually entge swivel directions by

inclination angle

42 and 44.

The pivot axis 48 is part of an adjusting device 50, whose structure and operation will be described below with reference to Figures 4 and 5.

The adjusting device 50 comprises a tool-side holder 52 (see FIG. 4), which is fixedly connected to a toothed counter-body 54 (cf. FIG. 5). The counter body 54 is penetrated by a pivot pin 56, which at least in the region of the counter body 54 has an external thread 58 which cooperates with a corresponding internal thread of the counter body 54.

The pivot pin 56 is part of a generally designated by the reference numeral 60 clamping screw, which comprises an actuating portion 62 (for example in the form of a wing handle) and a clamping body 64 which is rotatably connected to the pivot pin 56.

Along the pivot axis 48 of the pivot pin 56 seen between the counter body 54 and the clamping body 64, a rotary body 66 is arranged, which is part of the tool-side connecting portion 46 and is connected, for example, in one piece with a sleeve 32 shown in sections in FIG. The rotary body 66 has, on sides facing away from one another, projections 68 which, upon actuation of the clamping screw 60, interact in a form-fitting manner with recesses 70 which are formed on the clamping body 64 and the counter-body 54.

In the released state of the clamping screw 60 shown in FIG. 5, the rotary body 66 and thus the tool-side connecting section 46 can be pivoted about the pivot axis 48. Takes the tool-side connecting portion 46 a desired pivot position, the clamping screw 60 can be actuated so that the distance between the clamping body 64 and the counter body 54 is shortened so far that the rotary body 66 positively and thus rotatably received between the clamping body 64 and the counter body 54 is.

A further embodiment of a working device 10 shown in FIGS. 6 and 7 has a construction similar to the working devices 10 described above. Therefore, only the differences from the working devices 10 described above will be explained below.

In the working device 10 according to Figures 6 and 7, a handle-side connecting portion 28 is formed in the form of a perpendicular to the stem axis 14 of the handle 16 arranged opening. This opening is penetrated by a tool-side connecting portion 30 in the form of a pivot axis 48. In this way, the stem 16, starting from a straight basic position by

inclination angle

42 and 44 are pivoted about the pivot axis 48. In order to prevent the stem 16 from becoming detached from the pivot axis 48 in the axial direction, a securing element 49 passing through the pivot axis 48 (for example in the form of a cotter pin) may be provided.

For attachment of the stem 16 in the basic position or in an inclined position on the blade 18, a fastening device 68 arranged spatially separated from the pivot axis 48 is provided. The fastening device 68 is connected to the handle 16 and is pivoted together with this.

The fastening device 68 comprises a fastening bolt 70 with a free bolt end 72, which is designed to engage in one of a plurality of bolt receptacles 74. The bolt receivers 74 are arranged offset to each other on the tool 12, in particular in the blade 18, along a circular arc. The center of the circular arc is predetermined by the pivot axis 48.

The bolt 70 is held by means of a compression spring 76, which presses against a front, connected to the bolt 70 stop 78 in an engaged position of the bolt end 72 in one of the bolt receptacles 74. The stop 78 is welded to the bolt 70, for example, or secured to the bolt 70 by means of a securing element 80 (for example a splint).

The compression spring 76 is supported at its rear end on a rear stop 82, which is displaceable relative to the bolt 70. The rear stop 82 is supported on an outer side of the stem 16.

The stem 16 has a transverse, in particular perpendicular, to the stem axis 14 of the stem 16 extending bolt passage 84 for the passage of the bolt 70. The bolt 74 has at its end opposite the bolt end 72 a grip part 86.

By pulling on the grip part 86, the bolt 70 and thus also its bolt end 72 are pulled out of one of the bolt receptacles 74 against the action of the compression spring 76. This allows the pivoting of the handle 16 about the pivot axis 48 and the choice of another bolt receptacle 74, in which the bolt end 72 is latched by means of the compression spring 76.

To limit the Verschwenkwegs of the handle 16 12 Schwenkwegbegrenzer 88 are arranged on the back of the tool. These are either provided separately from or integrally formed with the tool 12 (for example, by bulges of the material of the blade 18).

A further embodiment of a working device 10 shown in FIGS. 8 to 13 has a construction comparable to the working device 10 described above with reference to FIGS. 6 and 7. Therefore, only the differences from the above-described working device 10 according to FIGS. 6 and 7 will be explained below.

In the working device 10 according to Figures 8 to 13, a fastening device 68 is provided with a fastening bolt 70 which passes through an arcuate recess 90 of the tool 12. The radius of curvature of the recess 90 corresponds to the distance of the fastening bolt 70 to the pivot axis 48 parallel thereto.

The

lateral boundaries

92 and 94 of the recess serve as Schwenkwegbegrenzer a pivoting path of the stem 16 about the pivot axis 48th

The fastening bolt 70 is connected on the front side of the active surface 23 of the tool 12 with a counter-holder 96. The counter-holder 96 is formed, for example in the form of a flat piece, which rests with its rear side on the active surface 23 of the tool 12.

On the side facing away from the counter-holder 96 of the fastening bolt 70, ie on the back of the tool 12, the fastening bolt 70 is connected to a clamping device 98. The tensioning device 98 comprises a hand-operated tensioning lever 100.

The clamping lever 100 is pivotable about a transversely, in particular vertically, to the fastening bolt 70 extending clamping axis 102. The tensioning lever 100 has a clamping surface 104 and a release surface 106. The clamping surface 104 and the release surface 106 are pivoted at a pivoting of the clamping lever 100 to the clamping axis 102 with. The clamping surface 104 and the release surface 106 preferably merge into one another continuously.

The distance between the clamping surface 104 and the clamping axis 102 is greater than the distance between the release surface 106 and the clamping axis 102nd

The fastening bolt 70 passes through the handle 16. A stop element 108 is provided on the side of the handle facing away from the tool 12. When the clamping surface 104 is clamped with the stop element 108, the tool 12 and the stem 16 are clamped between the counter-holder 16 and the clamping surface 104, so that the stem 16 and the tool 12 are fixed to each other and the stem in an initial position (see FIG. 8 and 9) or in a pivotal position (see FIGS. 10 and 11) is secured to the tool 12 (see FIG. 12).

When the tensioning lever 100 is aligned so that the clamping surface 104 is out of contact with the stop element 108 (see FIG. 13), the handle 16 is steplessly pivotable about the pivot axis 48 within the pivoting path defined by the recess 90. When the stem 16 assumes a desired position, the clamping lever 100 can be actuated again in order to clamp the clamping surface 104 with the stop element 108.

In a further embodiment, which is not shown in the drawing, the clamping surface 104 cooperates directly with a surface of the stem 16.

The tools 12 described above may be made of different materials, for example wood, metal, plastic or even composite materials.

The working devices 10 described above are particularly suitable for use in the home, but also in the commercial sector, for example in factories, in the construction industry, in gardening and landscaping, in agriculture, forestry or water.

It is understood that the stem 16 is connectable to different tools 12, such as the blade 18 or the slider 40. Also, similar tools 12 of different sizes and thicknesses may be provided.

The advantages described above with reference to the example of snow removal arise analogously for other materials such as sand, gravel, water, dirt or foliage.

The working device described above allows a considerable saving of human labor and allows a high ease of use.
