Description

[Detailed description of the invention] mat The present invention collects leaves, wood chips, and other debris from surfaces such as tennis court surfaces. This relates to mats that can be used.

The outside of a competition court, such as a tennis court, often has its surface regularly removed. Leaves and other debris that should be removed tend to accumulate.

According to the present invention, a mat for cleaning the ground is obtained, and the mat has a gap. , debris such as leaves and wood chips can pass through them and collect on the top surface of the mat. .

The mat may be constructed of a semi-rigid material such as rubber or a suitable polymeric material. It is desirable that

The gaps are long and narrow, and the longitudinal axis of each gap is approximately in the direction of mat movement. preferably facing the

The trailing edge of each gap should preferably be chamfered to lift debris to the top of the mat. It is desirable that The trailing edge of each gap faces perpendicular to the direction of travel or e.g. It can also be tilted at 45°. In this mat, all gaps are moved tilted relative to the direction of movement, or slightly relative to something else perpendicular to the direction of movement Can be tilted.

In one particularly useful form, mats are used to "back" clay tennis courts. A lattice-like structure is provided for the purpose of There is.

Therefore, the "backing" of a court during regular competition also occurs when the surface of the court is removed. and other debris.

Embodiments of the invention will now be described, by way of example only, in a diagrammatic representation of a mat according to the accompanying disclosure. side view, Figure 2 is an enlarged perspective view showing a portion of the trailing edge of one of the gaps; FIG. 3 is a plan view of a mat component formed in accordance with the present invention; 4 is a side view of the mat component of FIG. 3; FIG. 5 is similar to that of FIG. 3; a perspective view of a mat component incorporating a modified aspect; FIG. 6 is a plan view of a modified form of a mat formed in accordance with the present invention; FIG. 7 is a perspective view of the mat component forming portion of the mat of FIG. 6; FIG. 8 is a partially illustrated plan view of another type of mat component.

As shown in Figure 1 of the attached drawings, the mat backing the clay tennis court contains a grid of semi-rigid material. Preferably the mat is a lattice structure each having an outer edge 6 surrounding 7 and about 45 to the axis of the grid or to the edge of the component 4. Consisting of a row of separately formed rectangular elements 4 extending in ° This is desirable. The components 4 protrude from the edge 6 of one component and connect to the adjacent component. are fastened together by a protrusion that fits into a correspondingly formed hole in the adjacent edge of the element. Form a mat.

The strip 8 on the leading edge of the mat is provided with a lobed handle lO, by means of which the cord The mat can be drawn along the surface of the mat.

At least some of the components 4 form long gaps 12 within the lattice structure 7. ing. The first row 14 of the components 4 forming the mat will normally be compressed during the dragging operation. Since it is partially lifted from the Although it is not necessary to provide a gap 12, it is preferable to provide a gap 12 in each of the other components as much as possible. It is desirable that However, it is important to provide clearance for all other components. Only a few other components are properly distributed along the length and width of the mat. As long as the gap is provided, sufficient results can be obtained.

The longitudinal dimension of each gap 12 corresponds in this case to that of the grid. Cedar cradled pa To define a turn, the gap 12 between adjacent components in the same row is preferably It is desirable to slope in the opposite direction. Alternatively, some or all of the gaps 12 , may be substantially perpendicular to the direction of movement.

As shown in FIG. The protruding edge portion 18 is chamfered by shaping. As shown, this As a result, a finger element 18a that protrudes forward is formed. The chamfered part of the trailing edge is Facilitates lifting of debris to the top of the mat. The front edge 20 of each gap 12 is also chamfered. can be used.

In a modified embodiment with a gap inclined with respect to the direction of movement, the protruding edges of the grating 7 The abutment portion 18 can be tilted for direct alignment with the direction of movement of the mat. Ru.

The lower edge 22 of the protruding edge portion I8 also extends below the lower surface of the grid 2 to Lifting of debris to the upper surface can be further facilitated.

As the mat is dragged along the clay court to back the surface, , which also coats and maps debris such as leaves by passing it through the gap. It has the effect of collecting on the top surface of the object. Not all of the debris is necessarily collected in one pass. Although not guaranteed, continuous backing of the coat will ensure that all debris is completely removed. It will help you.

The gap also acts to reduce the frictional drag of the mat.

The mats specifically described are primarily used to remove debris while backing the coat. Although designed for clay courts, this mat can also be used simply for foliage or other clay courts. For the purpose of removing other debris, such as lawns and playgrounds, people's courts or It can also be used on the grassy surface of the pond. This mat is also suitable for concrete Hard materials such as “Plexipave J” (trade name) It has also proven effective in collecting leaves and other debris on surfaces.

This mat can also be used to clean beaches and other surfaces to remove debris. Can be used. For this purpose, this mat does not necessarily have to have a grid-like structure. . If it is likely to consist of debris, bottles or other relatively large materials, the gap should be The size is suitable for accommodating.

The mat component 4a in FIG. 3 and the component 4b in FIG. It is generally similar to that of Figures X, 2, 3, 4 and 5. Similar parts are designated by like reference numerals. In these examples, the component side A gap 12 extends from the front to the side, and a central reinforcing rib 30 extends from the front to the rear. is provided. Figures 3, 4 and 5 also show that the outer edges actuated in conjunction with each other. The protrusions 32 and recesses on 6 are shown and they are structural elements to form a mat together. Allows for a plain snap fit.

In FIG. 5, component 4b is a lattice-like structure defining the leading edge of gap 12. A portion thereof is provided with a row of upright protrusions 36. These are the pickups on structure 7. It helps to retain the broken debris. They are placed on the side edges or rear of the structure 7. may be provided in additional or alternative positions of components 4.4a, 4b, such as can. It is also possible to have more than one column, such as these staggered columns. Tsuki The outlet may be in the form of a spigot as shown, or alternatively, it may be straight. It may also be formed by an upright fence-like structure.

The modified mat shown in FIG. 6 is of similar form to that of FIG. 1, but with the components 4C is in this case of hexagonal form, as shown in detail in Figure 7, and the gap 12 is , extending at 90° with respect to the parallel sides 6a, 6b of the edge 6 extending front to back.

Component 4c snaps together in a similar manner to components 4.4a, 4b. It will be done. As shown, an upright protrusion is provided in this case as well. Component The anterior portions of 4C may together be adapted to impart a serrated leading edge to the mat. However, the present applicant et al. 4C and snap-fit them to components in the mat to create straight edges. It is considered preferable to form a mat.

In this case as well, the component is provided with reinforcing ribs 30 that extend forward and backward. , these extend from the front tip of the component to the rear tip.

The mat component 4d of FIG. 8 is somewhat similar to that of FIGS. 6 and 7.

The mat components 4c, 4d have a gap located intermediate between their front and rear ends. 12, but these gaps are located closer to the front or rear end. You may do so. The former is shown in FIGS. 6, 7 and 8. In any case, As shown, gaps 12 lined up in component 4C or 4d are located at the edges of the mat. It can be aligned in the direction from the end to the end.

The above-mentioned mats may be made of plastic material, for example, or may be made of other materials. It can also happen. For example, forming it from a relatively hard material such as metal Can be done. Preferably in this case too, the material is thereby relatively flexible and/or A resilient structure should be formed. In any case, this, however, is formed. The structure is a tennis court with an overall end-to-end dimension of approximately 2 to 3 m. dimensions larger than those used in typical structures designed primarily for , may be of different sizes.
