Description

Grass protection mat {GRASS PROTECTION MAT}

The present invention relates to a grass protection mat that can be used for lawn protection in a golf course, grass field, park lawn, or the like, or can also be used for grass growth. More specifically, it is prevented from slipping on the mat, in particular after construction of the mat. By preventing the mat from sinking in the ground, the grass protection by the mat is continuously maintained, and the grass growth space of the hexagonal or octagonal shape is formed, so that the grass is smooth and the grass damage is caused by the mat buffer wing. And a grass protection mat to facilitate the construction of the mat connection through the hook while maintaining the overall mat firmness.

In the grass growing areas such as golf courses, lawn fields, and lawns of parks, lawns in the main road areas where mainly aisle parts and vehicles, for example, carts in golf courses, are constantly pressed and damaged. Renovation of the turf will require significant costs.

Therefore, a grass protection mat for preventing the damage of the grass while buffering the load even if a person or vehicle passes in order to prevent the lawn damage in the grass moving area, such as people or vehicles, such as the grass growing area.

On the other hand, the conventional grass protection mat known so far is not shown in a separate drawing, but generally has a rectangular grass turf space, the lugs supported on the ground vertically formed in the lower portion of the body of the checkerboard form, the upper portion of the body There are vertical pillars supporting a person or a vehicle, especially when a cart of a golf course passes, at regular intervals. Between these vertical pillars, the upper part of the body is smoothed by the wheel of a person's shoes or a vehicle (cart) passing through the mat. Cushioned wings are provided to provide a cushioning function to distribute the load while being pressed, and hooks are connected to the outer parts of the body to connect the mats.

However, in such a conventional grass protection mat, since the edge of the buffer blade is sharp, the grass is pressed and damaged or severely cut at this sharp edge, since the openings of the hooks connecting the mats face upward. When the mats are connected, the mats must be connected in the direction of lifting the mats, so the mating work is also inconvenient, especially since the bodies are connected in a rectangular shape to form a checkerboard as a whole. There are various problems, such as the growth of the grass and the slippage of the grass, because the space is narrower than the hexagonal or octagonal shape.

On the other hand, another conventional grass protection mat has been proposed in the registration utility model 20-0346130 registered by the applicant of the present invention dated March 15, 2004 to improve the problems caused by the conventional grass protection mat of the checkerboard type.

That is, another conventional grass protection mat disclosed in the registration utility model is not shown in a separate drawing, but the edge of the buffer blade to smooth the edge of the grass to prevent damage, in particular by connecting the body in a hexagonal shape to form a body portion In addition, by expanding the growth space of the turf to smooth the sliding through the mat after the construction of the mat, while improving the firmness of the mat through the reinforcing ribs provided between the lugs.

However, in other conventional grass protection mats such as this, after the grass protection mat is constructed on the ground, the grass is grown and covered with sand for the protection of the grass, or the ground is softened by moisture in the rainy season, so that the mat easily sinks. There was a problem, and the grass protection mat so recessed there was a problem that can not provide a normal function to protect the grass.

In addition, other conventional grass protection mats have a smooth surface on the cushioning wings that contact most people's shoes, so that people who pass on the mat can easily pass through the snow in winter or in the autumn when morning dew occurs frequently. It slips, which causes a safety accident for a person who passes through the area where the lawn protection mat is installed.

In addition, in order to further expand the turf growth space, there has been a need for other types of lawn protection mats that form the body of the mat by connecting the bodies in an octagonal form.

The present invention has been devised to improve the above-mentioned problems, and its purpose is to more effectively prevent a person passing through a grass protection mat from slipping on the mat, and to easily remove it from the ground even after the grass protection mat has been constructed. The grass protection by the mat can be continuously maintained because it is not recessed, thus extending its service life, and since the bodies are formed in a hexagonal or octagonal shape, the grass growth space is expanded than the existing square, so that grass growth on the mat The present invention provides a grass protection mat that improves grass protection as a whole.

1 to 4 show the overall configuration of the grass protection mat 1 according to the present invention in a perspective view, a bottom view, a top view and a front view. The grass protection mat 1 of the present invention has a large skeleton of the mat. The body part 10 and the lug 20 supported on the ground, the protrusion pillar 30 which receives a load, the buffer wing 40 which distributes and buffers a load, and the outer frame part 50 which hold | maintain the outer frame of a mat It includes, and is provided with a lug prevention means (60) provided on the lug to prevent the ground depression of the mat, and a non-slip means (70) provided on the cushioning wings, these components (10, 20) Looking at (30) (40) (50) (60) (70) as follows.

First, Figures 1, 3 and 4 shows the body portion 10 of the lawn protection mat 1 of the present invention in detail, the body portion 10 of the present invention is such as grass growth or lubrication A plurality of bodies 12 are integrally connected to form a grass growth space (12a) of the hexagonal shape to improve the sex to form a skeleton of the overall mat.

That is, since the bodies 12 of the grass protection mat 1 of the present invention are connected to each other to form a hexagonal shape, the grass growth space 12a is wider than the conventional rectangular mat, and the grass photosynthesis action is more smoothly. In this way, the mat is more smoothly grown or slid after the construction of the mat, in fact, the hexagonal body portion 10 can maintain the optimum strength.

And, as shown in Figure 1, the body 12 is formed so as to round the at least the upper surface (12 ') of the protrusion pillar 30 or the buffer blades 40 to be described later integrally formed integrally It is preferable to prevent this, if the upper surface of the body 12 is angled to form a corner, because the grass is pressed against the upper edge of the body and damaged when a vehicle wheel such as a person or a cart passes. .

Next, FIGS. 1, 2 and 4 show the lugs 20 of the lawn protection mat 1 of the present invention, which is provided at the bottom of the bodies 12. In this case, the lugs 20 may be preferable in that the bodies 12 are formed at the connection parts, that is, the intersection points, to maintain the strength of the mat.

However, since the lugs 20 of the present invention have a body 12 formed in a hexagonal shape and installed at the bottom thereof, an intersection point of a body connection portion is increased rather than a quadrangular shape, and the lugs 20 protrude vertically to this portion. Because of this, the number of lugs 20 installed on the mat as a whole can be increased to improve the firmness of the mat.

At this time, as shown in Figures 4 and 10, the gap portion 24 between the lugs 20 is formed in an arc shape, minimizing turf damage by avoiding pressing the grass from the lug portion as much as possible after mat construction I will.

Next, FIGS. 3 and 4 illustrate the protruding pillar 30 of the grass protection mat 1 of the present invention, and the protruding pillar 30 of the present invention includes a body of the body portion 10. 12) It is formed so as to support the load is formed integrally perpendicular to the upper surface.

That is, similar to the lug 20, the protruding pillar 30, the body 12 is configured in a hexagonal connection, can be installed perpendicular to the intersection point that the body 12 is connected, which is a square The number of installations is increased rather than the shape, so that even if a person or a vehicle (golf cart) passes, the turf is reliably supported while minimizing turf damage.

Next, Figures 1, 3 and 8 shows the buffer wing 40 of the grass protection mat (1) of the present invention, such a buffer wing 40 of the present invention is the body portion 10 of the The body 12 is formed vertically integrally between the protruding pillars 30, wherein the buffer wings 40 should be formed longer than the protruding pillars 30.

Therefore, when a person or a cart of a golf course passes over the grass protection mat 1, first, the contact with the buffer wings 40 having the longest height and the largest number of installations is bent, and the buffer wings 40 are bent. The turf is protected by the mat because the load for pressing the turf is dispersed and buffered, and then is supported by the protrusions 30.

At this time, as shown in Figure 8, the buffer blades 40 are formed so that the edge portion 42 is further protruded relative to the center line rounded gently, so that the grass edges 42 of the buffer blade (40) It is prevented to be pressed while being damaged by.

In addition, the buffer blades 40 are formed between two protrusions integrally formed between the protruding pillars 30, but are not necessarily limited thereto, and the flat surfaces 40a of one side are arranged so as to face each other opposite to each other. By bending the wings 40 to be opposite to each other, the buffering effect can be enhanced.

On the other hand, as shown in Figure 1, the buffer blade 40 is provided with a non-slip means 70 is integrally formed on the surface.

That is, when the buffer wing 40 is formed, it is to be provided with a non-slip means 70 formed on the surface of the knurled surface.

Therefore, since the surface of the cushioning blades 40 in direct contact with the sole of the person passing through the mat is provided with non-slip means 70 formed of a knurling surface, the person passing through the grass protection mat slips. This will effectively prevent them, especially during winter and rainy seasons with heavy snow, or when slipping on the morning dew will minimize slippage on the mat.

Next, FIGS. 1 and 3 illustrate the outer frame portion 50 of the grass protection mat 1 of the present invention, and the outer frame portion 50 of the present invention is the outer portion of the body portion 10. It is integrally connected in a rectangular shape and substantially maintains a mat shape.

In addition, the lugs 52 are arranged at a predetermined interval on the bottom of the outer frame portion 50, and the buffer wings 40 are formed at a predetermined interval on the upper portion thereof.

Meanwhile, hooks 54 are installed at one side of the outer frame part, which is shown in detail in FIG. 9.

That is, when the hooks 54 shown in FIGS. 3 and 9 are connected to the mats, an opening portion 56 is formed to which the outer frame portion 50 of the adjacent mat 1 is fitted, and such hooks 54 are formed. It is integrally formed in an L-shape integrally bent on the upper surface of the outer frame portion 50, the lower end is formed with a projection (54a) supporting the outer frame portion 50 is integrally formed.

At this time, the hook 54 of the present invention, as shown in Figure 9, the opening 56 is facing down to facilitate the construction while pressing the mat (1).

Next, Figures 1 to 4 shows the depression preventing means 60 of the grass protection mat (1) of the present invention, as described above, to prevent the depression of the mat excessively in the ground 60 is provided on the lug 20.

That is, the depression preventing means 60 of the present invention is provided in a suitable position or shape in the lug 20 supported on the ground, thereby preventing the mat 1 from sinking in the ground, for example, a grass protection mat ( After the construction of 1) in a golf course, the sand cover to protect the growth of the grass, or the rain is rainy rainy season, the ground softens the lug 20 is excessively lodged in the ground, the sinking prevention means (60) It is to solve the problem that the grass can no longer protect the grass while being immersed in the ground even after the actual grass protection mat (1) is constructed.

On the other hand, the depression preventing means 60 can be arranged in various ways as needed, for example, as shown in Figure 3 it will be possible to arrange uniformly at five points on the basis of the entire mat.

In addition, as shown in Figure 6, it may be possible to arrange between the lugs 20 in the form of a checkerboard, or as shown in Figure 7, to arrange the anti-depression means 60 in a diagonal direction with respect to the center It would also be possible.

Next, Figure 5 shows several embodiments of the sink preventing means 60 of the present invention.

That is, as shown in Figure 5a, the depression preventing means of the present invention may be composed of a bar-shaped first integral depression prevention means (60a) integrally connected between the lower end of the adjacent lugs 20, this In the case of making the mat integrally formed, it will facilitate the production.

Next, as shown in Figure 5b, the depression preventing means of the present invention may be composed of a second integral depression preventing means (60b) formed integrally in a conical shape that the outer diameter is extended to the lower end of the lug 20, this In this case, since the portion of which the outer diameter is expanded is considerably wider than the lug 20, it will effectively prevent the mat from sinking in the ground, and in this case, it will be easy to manufacture because it is formed integrally during the mat manufacturing.

In addition, as shown in Figure 5c, the depression preventing means of the present invention is to be composed of a locking type depression preventing means (60c) for fastening a wire, for example, an electric copper wire or the like fastened between adjacent lugs (20). In this case, it will be desirable to form a fastening groove 22 in the lug 20 to facilitate the fastening of the fastening-type depression preventing means 60c, which is a wire such as an electric copper wire, and at the same time, also to fasten the fastening state. .

Therefore, in the case of using the fastening type depression preventing means 60c in the form of a wire such as an electric copper wire, it will be practical since it will be possible to use the grass protection mat 1 that is already being constructed or stored because it is not integrated. .

Finally, as shown in Figure 5d, the sinking prevention means of the present invention may be composed of a detachable sinking prevention means (60d) formed of separate moldings sandwiched between adjacent lugs (20).

At this time, such a detachable depression preventing means (60d) is formed of a molding consisting of a detachable portion 62 to be fitted to the lug 20 and a connecting portion (64) connecting between the fastening type depression preventing means ( Like 60c) it will be possible to use in the grass protection mat (1) already in use or stored, and can be used as a separate component, the detachable portion 62 is inserted into the lug 20 in the form of interference fit. For example, the inner diameter of the hole of the detachable part 62 may be varied so that once it is fitted in the lug 20 in the form of interference fit, it is no longer necessary to rise upward along the lug 20.

Otherwise, the inner diameter of the detachable portion 62 of the detachable depression preventing means 60d may be constant, and the lug 20 of the detachable portion 62 may be manufactured in a form in which the outer diameter decreases toward the lower end of the lug 20. Fixing will be possible.

Accordingly, in the turf protection mat 1 of the present invention, the lug 20 vertically formed on the lower part of the body 12 is provided with one of the first, second, first, and second types of recess preventing means 60. By doing so, it is possible to continuously protect the grass by preventing the grass protection mat 1 from being excessively recessed on the ground, and furthermore, the mat is prevented by the non-slip means 70 of the knurled surface formed on the buffer wing 40. Prevent accidents caused by slipping of people passing by.

Next, FIG. 11 shows the reinforcement ribs 80 provided between the lugs 20 of the grass protection mat 1 of the present invention, and the reinforcement ribs 80 of the present invention have the body portion 10. It is formed integrally connected between the bottom of the body 12 and the bottom side lugs 20, 52 of the outer frame portion 50, the reinforcing rib 80 is the depression preventing means 60 is the lug 20 In contrast to being connected to the lower side of the, the upper side of the lug 20 is formed integrally adjacent to the body 12 to maintain the overall firmness of the mat.

At this time, as shown in Figure 11, the reinforcing ribs 80 are disposed in the diagonal direction with respect to the center of the mat is most preferable in terms of maintaining the mat firmness, the reinforcing ribs 80 and the depression preventing means 60 Since silver is formed with a height difference in a lug, even if the arrangement | positioning overlaps, it does not become a problem.

Next, FIG. 12 illustrates a mat in which the body 12 is octagonally connected to the grass protection mat 1 according to the present invention, thereby widening the grass growth space 12a more than the hexagonal shape of FIG. 1.

That is, as shown in FIG. 12, since the bodies 12 are formed by connecting the bodies 12 in an octagonal form, the grass growth space 12a inside the bodies 12 is the hexagonal shape of FIG. 1. Rather wider, which will make turf growth or lubrication easier.

By the way, since the case of the body 12 in the hexagonal form is easier in terms of production and better in strength than in the case of the octagonal form, the body portion 10 of the hexagonal or octagonal shape depending on the environment of the construction area It may be desirable to configure, for example, the grass protection mat constituting the octagonal body portion 10 of the grass more photosynthetic action is more smooth in areas where sunlight is not good, and in the sunny areas than octagons Easy to manufacture and excellent strength should also use a grass protection mat composed of a hexagonal body portion 10.

On the other hand, the grass protection mat (1) of the present invention is a structure that is injection molded integrally as a resin material, specifically, it is preferable to be molded of a soft polyethylene (LDPE), in this case hard or hard when passing through This is because the buffering capacity will be better than the material.

In addition, the grass protection mat (1) of the present invention is installed in a golf course, etc., and thus continuously exposed to sunlight (ultraviolet rays), so the life is shortened, in order to prevent this, for example, polyethylene and UV blocking material, which is a resin material during injection molding of the mat, It is also possible to combine the Ultra Biolet sunscreens (UV sunscreens) together to form an integral injection molding or to coat the surface of the injection molded mat 1 with a sunscreen coating, in which case the use of a grass protection mat Will extend the life.

In addition, since most domestic golf courses are grass grown mainly in the summer, not in the four seasons, there is a difference in the color of the grass during the dormant period from the growing season to the late autumn and winter seasons. In the dormant phase, it would be more desirable to have a straw color.

Thus, according to the present grass protection mat provides the following excellent effects.

First, after the lawn protection mat is installed on the ground by the depression preventing means provided between the lugs of the mat, it is possible to protect the lawn continuously by preventing the depression.

Second, the surface of the cushioning wings of the grass protection mat is not slippery to further reduce the blur of the passengers or vehicles passing through the grass protection mat in winter.

Third, in addition to the hexagon, the grass growth space of the octagonal form is formed if necessary to increase the grass lubrication by a more smooth photosynthesis action.

Finally, the edges of the cushioning wings are smooth to prevent turf damage, wider air gaps between the lugs to prevent grass from being squeezed, reinforcement ribs to increase mat firmness, while the hooks open downwards It is to facilitate the connection construction to provide a more practical grass protection mat as a whole.

While the present invention has been shown and described in connection with specific embodiments so far, it is understood in the art that the present invention may be variously modified and changed without departing from the spirit or the scope of the present invention provided by the following claims. Those of ordinary skill will want to know easily.
