Description

[0001] The invention relates to a lawn squeegee.

[0002] A lawn squeegee is used, for example, to sand lawns.

[0003] Based on this, the task is to create an improved lawn rake.

[0004] This object is achieved by a lawn squeegee according to claim 1. Advantageous embodiments and further developments emerge from the subclaims.

[0005] Advantageously, handling of the lawn squeegee can be made easier if one corner of the lawn squeegee is designed with a shape that deviates from a right angle.

[0006] A suitable lawn squeegee has the following features: a floor part with a surrounding frame and a plurality of struts extending within the frame, wherein at least one corner section of the frame is formed as an arch or as a slope; and a fastening device arranged on the base part and shaped to attach a handle for handling the lawn squeegee.

[0007] The base section can be pulled across the lawn using the handle, for example. The shape of the base section can be used to distribute sand on the lawn, for example. The base section with the frame and the struts can be shaped like a known lawn squeegee, apart from at least one corner section. The frame can be rectangular, with the frame segments, which for example run in a straight line, not converging at right angles at one, two, three or all four corners of the frame, but being connected by a corner section that is, for example, curved or diagonal to the longitudinal axes of the straight frame segments. The corner section can be understood to be a corner segment of the frame that has a center line several centimeters long that is curved or diagonal to the longitudinal axes of the adjacent frame segments to be connected.Thus, the corner section may differ from a right-angled corner segment that is merely provided with a slightly rounded or slightly bevelled edge.

[0008] The lawn squeegee, also known as a squeegee, differs from conventional lawn squeegees according to one embodiment in particular in that the corners are rounded, which prevents them from jamming on uneven grass surfaces. This prevents the turf from being damaged, whereas sharp 90-degree corners could cut into the turf if they jam. Since there is no sudden stop due to jamming, the squeegee described here is easy and comfortable to work with. In general, this squeegee glides very well. In addition, the squeegee glides better when spreading the sand on the lawn, which makes work considerably easier. The technical improvement implemented here enables the same result with significantly less labor. The lawn squeegee according to one embodiment is shaped with rounded corners or corners at a 90-degree angle.

[0009] The fastening device can, for example, comprise one or more elements with which the handle can be attached to the base part. Known fastening methods can be used. Depending on the design, at least one corresponding element of the fastening device can be formed as a component of the base part. The fastening device can be shaped to movably fix the handle to the base part.

[0010] At least one corner section of the frame can be shaped as an arch or a slope with an outer length of more than 3 cm or more than 5 cm. By making the corner section large, tilting of the floor section when moving it across the floor can be prevented. The arch can have a circular curvature or a different type of curvature.

[0011] For example, the at least one corner portion of the frame may be formed as an arc with an outer radius of more than 5 cm.

[0012] When the at least one corner portion of the frame is formed as the arc, an outer side of the corner portion may have a different curvature shape from an inner side of the corner portion or the same curvature shape.

[0013] If the frame has four corner sections, these can be shaped identically or differently. Thus, a first corner section of the frame can be shaped as an arch or a slope, a second corner section of the frame can be shaped as an arch or a slope, a third corner section of the frame can be shaped as an arch or a slope, and a fourth corner section of the frame can be shaped as an arch or a slope. The shapes of the arches or slopes of the individual corner sections can be the same or different.

[0014] The frame can have a first longitudinal section connecting the first corner section and the second corner section, a second longitudinal section connecting the third corner section and the fourth corner section and opposite the first longitudinal section, a first transverse section connecting the first corner section and the third corner section, and a second transverse section connecting the second corner section and the fourth corner section and opposite the first transverse section. For example, the longitudinal sections can each be straight. The transverse sections can each be straight or curved. For the squeegee to function very well, the long sides are straight. The short sides, however, can also be curved if this supports the intended use.

[0015] The longitudinal sections can be longer than the transverse sections.

[0016] For example, the longitudinal sections can be between 50 cm and 100 cm long. For example, the transverse sections can be between 20 cm and 40 cm long.

[0017] For example, the corner sections and / or the longitudinal sections and / or the transverse sections may have a width between 2 cm and 5 cm.

[0018] The frame may have a floor and an outer wall. An edge connecting the floor and the outer wall may be at a right angle. This can facilitate manufacturing.

[0019] Alternatively, the edge connecting the floor and the outer wall can be rounded. This can improve the handling of the lawn squeegee.

[0020] This allows the corners to be rounded toward the bottom. For example, the squeegee has a rounded edge with a radius of R10. Alternatively, a design with a 90-degree angle can also be realized.

[0021] The edge can have a radius between 5 mm and 15 mm.

[0022] The base part can be formed from sheet metal. For example, several parts formed from sheet metal can be welded or soldered together.

[0023] The fastening device can comprise at least one support element. The support element can be arranged transversely to the plurality of struts. Optionally, the support element can have a through-hole for receiving a bolt that can be passed through the stem. For example, two corresponding support elements can be arranged parallel to each other. The support element can be integrally connected to the frame and / or the struts.

[0024] The lawn squeegee may include the handle attached to the attachment device.

[0029] The frame 110 is rectangular, but does not have right-angled corners, but rather curved corner segments, which here are formed by a first corner section 121, a second corner section 122, a third corner section 123, and a fourth corner section 124. The frame 110 further comprises a first longitudinal section 131 connecting the first corner section 121 and the second corner section 122, a second longitudinal section 132 connecting the third corner section 123 and the fourth corner section 124 and opposite the first longitudinal section 131, a first transverse section 133 connecting the first corner section 121 and the third corner section 123, and a second transverse section 134 connecting the second corner section 122 and the fourth corner section 124 and opposite the first transverse section 133. The longitudinal sections 131, 132 are each formed as rectilinear sections.The transverse sections 133, 134 are also each formed in a straight line, but can alternatively also be curved.

[0030] According to one embodiment, the longitudinal sections 131, 132 and the struts 112, 114, 116 are arranged parallel to one another. The struts 112, 114, 116 are spaced apart from one another and from the longitudinal sections 131, 132. The number of struts 112, 114, 116 is chosen merely as an example.

For example, the outer length of the corner sections 121, 122, 123, 124 is more than 3 cm, more than 5 cm, or more than 10 cm. For example, the corner sections 121, 122, 123, 124 each have an outer radius of more than 5 cm.

[0032] According to one embodiment, the corner sections 121, 122, 123, 124 also have a curved profile over their entire inner length.

[0035] According to one embodiment, both the frame 110 and the struts 112, 114, 116 are formed from sheet metal. Alternatively, the base part 102 is made of plastic, for example.

[0036] According to an alternative embodiment, not all corner sections 121, 122, 123, 124 are designed as an arc, but at least one of the corner sections 121, 122, 123, 124 is rectangular or shaped as a slope. A corresponding slope has, for example, an outer length of more than 5 cm. The slope can be rod-shaped and aligned obliquely to the adjacent longitudinal section and the adjacent transverse section. All corner sections 121, 122, 123, 124 can also be shaped as slopes.
