The present invention relates to a grass protection mat that can be used for grass protection in a golf course, grass field, park grass field, etc., or can also be used for grass growth, and more particularly, in order to prevent the phenomenon of sinking into the ground. It is provided with a depression preventing means to be compressed, and the bottom surface of the depression prevention means is formed in a concave shape of the center portion relates to a grass protection mat is configured to generate a greater bearing force.

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 turf damage, especially in the copper moving area in which such people or vehicles move.

Such known conventional grass protection mats are disclosed in Korean Utility Model Registration No. 20-0354896 filed by the applicant of the present invention.

For example, although not shown in a separate drawing, the conventional grass protection mat is largely the body portion constituting the skeleton of the mat, the lugs supported on the ground, the projection pillar supporting the load and the cushioning wings for dispersing and cushioning the load, and the mat It includes the outer frame part to keep the outer frame of the base.

In addition, the outer frame portion has hooks that enable connection construction of the mats and openings to which hooks of adjacent mats are fastened are formed at predetermined intervals on opposite sides along the outer frame portion.

Therefore, the lugs and the protruding pillars support the load applied by the person or the vehicle passing through the mat, and the cushioning blades distribute the load applied to prevent the damage of the grass that grows as a whole.

On the other hand, the registration utility model has been disclosed to prevent the depression of the mat.

For example, after the grass protection mat is installed on the ground, the grass grows and covers the sand to protect the grass, or during the rainy season, the ground softens by moisture, causing the mat to easily sink into the ground. Recession of the grass protection mat as described above has a problem that it is difficult to protect the grass normally and continuously, or the mat is depressed into the ground can not normally protect the grass grown. The sink preventing means is to prevent the above problems, it is configured to prevent the phenomenon that the grass protection mat is buried underground by increasing the area in contact with the ground.

However, in the registration utility model, the depression preventing means proposed by the applicant of the present invention has been proposed in the form of a wire simply extending between a pair of adjacent lugs or in the form of a flat plate coupled to the lower end of the lug. In this case, when the depression preventing means is formed in the form of a wire, the effect of increasing the area in contact with the ground is insignificant. When the depression preventing means is formed in the shape of a flat plate, the effect of preventing depression is greater than that in the case of being formed in a wire shape, but load is applied. Repeatedly there is a problem that the depression prevention means of the flat plate shape is also recessed into the ground.

The present invention has been made in order to solve the above problems, it is an object of the present invention to provide a grass protection mat configured to improve the phenomenon of sinking into the ground after receiving a repetitive load applied to the ground. .

Hereinafter, with reference to the accompanying drawings will be described in detail an embodiment of a lawn protection mat according to the present invention.

1 is a plan view of a grass protection mat according to the present invention.

Lawn protection mat according to the present invention is a structure for protecting the grass from the user or moving body that is settled on the ground where the grass is embossed, as shown in Figure 1 to have one or more grass passing space 110 It is coupled to the body portion 100 and the lower surface of the body portion 100 is provided on the lower side of the body portion 100 is formed in the plate-shaped depression preventing means 200 is seated on the ground, so as to project downward Two or more lugs 300 are to be coupled to the upper surface of the body portion 100 to protrude upward and the bending buffer 400 having elasticity to be restored when the load is released by being bent by the load applied to the upper side of the mat And a protrusion pillar 500 coupled to the upper surface of the body portion 100 to protrude upward to support a moving body load such as a person passing through the mat.

The body part 100 includes a plurality of grass passing spaces 110 so that the grass grows in the sunlight, the grass passing spaces 110 are arranged along the ground, that is, in the horizontal direction. At this time, the body portion 100 is formed in a bar shape (bar) so that the grass passing space 110 can be more widely secured, it is preferably formed in a hexagonal shape to maximize the durability and stability in the horizontal direction. Accordingly, in the present embodiment, the grass passing space 110 is formed in a hexagonal shape, but the shape of the grass passing space 110 is not limited thereto and may be changed to a polygon or a circle such as a quadrangle.

In addition, the fastening protrusions 120 and the fasteners 130 are formed on the outside of the body portion 100, so that the user can continuously connect a plurality of grass protection mats.

The depression preventing means 200 is a component for preventing the phenomenon that the grass protection mat according to the present invention is installed in the ground and the ground caused by the load of a user or a moving object, etc. passing over the grass protection mat, the contact with the ground It is formed in a plate shape having a width in a direction parallel to the ground to increase the area. Therefore, the grass protection mat according to the present invention is prevented from sinking into the ground because the depression preventing means 200 is supported on the ground even if the bottom surface is pressed against the bottom by receiving a downward load to support the downward load.

At this time, the depression preventing means 200 may be coupled to the body portion 100 to be disposed between the different lugs 300, as shown in Figure 1, may be coupled to the lower end of the lug 300 have. When the depression preventing means 200 is disposed between the different lugs 300, both the bottom of the depression preventing means 200 and the lower end of the lug 300 serve to support the downward load, so that the depression into the ground There is an advantage that the phenomenon can be prevented more effectively, when the depression preventing means 200 is coupled to the lower end of the lug 300, the configuration of the product due to the integration of the lug 300 and the depression preventing means 200 is integrated The simplicity has the advantage of easy manufacturing.

The lug 300 is a component for separating the body part 100 from the ground, and is uniformly arranged to evenly support each part of the body part 100. That is, when the body part 100 is formed in a polygonal shape, it is coupled to each vertex of the body part 100, and when the body part 100 is formed in a circular shape, a predetermined interval along the body part 100 is provided. Put together to be arranged. In addition, the protruding pillar 500 is a component that receives a user or moving body load passing through the mat, similar to the lug 300, when the body portion 100 is formed in a polygon, each of the body portion 100 It is coupled to the vertex, when the body portion 100 is formed in a circular shape is coupled to be arranged at regular intervals along the body portion (100).

Since the lug 300 and the protrusion pillar 500 are the same as the lug and the protrusion pillar which are applied to the conventional grass protection mat, detailed description thereof will be omitted.

The buffer blade 400 is formed between the protrusion pillars 500 of the body portion 100, the buffer blades 400 formed in this way is formed longer than the height of the protrusion pillar 500, the load first Disperse

That is, the user or the moving object passing over the grass protection mat first comes into contact with the buffer blades 400 having the longest height and the largest number of installations, and the buffer blades 400 are bent by the load of the user or the moving object. It serves to distribute and cushion the load. In this case, the direction in which the shock absorbing blade 400 is bent and the effects thereof will be described in detail with reference to the accompanying drawings.

FIG. 2 is a partial cross-sectional view of the grass protection mat according to the present invention cut along the AA line shown in FIG. 1, and FIG. 3 is a partial cross-sectional view of the grass protection mat according to the present invention cut along the BB line shown in FIG. 4 and 5 show an example of use of the lawn protection mat according to the present invention.

One of the greatest features of the grass protection mat according to the present invention, as shown in Figures 2 and 3 is that the bottom of the depression preventing means 200 is concave, that is, all or part of the outer end of the bottom is lower than the center It is formed. At this time, the bottom surface of the depression preventing means 200 may be formed such that both ends in one direction extend downward and the recess is concave, as shown in the present embodiment, the entire outer end is extended downward and only the center point portion may be concave. have.

When the bottom surface of the depression preventing means 200 is formed concave, when the ground is compressed by the downward load (shown by the solid arrow) as shown in Figure 4 soil particles are inclined of the depression prevention means 200 The bottom surface is concentrated in the middle (shown by dashed arrows), so the soil particles are compressed more densely. As such, when the soil particles are compactly compressed, the soil becomes harder, and the depression preventing means 200 has an advantage of supporting the downward load more stably.

In addition, when the downward load is very large and the depression preventing means 200 is flattened as shown in FIG. 5, both ends of the depression preventing means 200 are advanced toward the outside, respectively, and thus the depression preventing means. (200) The soil located at both ends of the soil is compressed to densify the particles, and the soil is compressed to generate a reaction force that prevents the sink preventing means 200 from being flattened.

Therefore, the downward load applied to the depression preventing means 200 is dispersed by the force of depressing the depression preventing means 200 into the ground and the force of flattening the depression preventing means 200, so that the depression preventing means ( 200) is greatly reduced the phenomenon that the depression into the ground by the downward load. That is, the depression preventing means applied to the conventional aphid protection mat can support the downward load as much as the soil can support the depression preventing means upward, the depression preventing means 200 applied to the present invention is The soil may support a downward load by the amount of the force supporting the depression preventing means 200 upward and a reaction force that prevents the depression preventing means 200 from being flattened.

In addition, as shown in FIG. 5, when the downward load is removed while the depression preventing means 200 is flattened, the depression preventing means 200 returns to its original state, that is, the bottom surface is concave by its elastic force. The depression preventing means 200 is raised to the center because the bottom surface is supported by the soil. Therefore, since the body portion 100 coupled to the upper side of the depression preventing means 200 is raised by a height at which the center portion of the depression preventing means 200 rises, the phenomenon of sinking into the ground is further prevented.

6 is a bottom perspective view of the depression preventing means 200 applied to the grass protection mat according to the present invention, Figure 7 is a perspective view of a second embodiment of the depression preventing means 200 applied to the grass protection mat according to the present invention. 8 is a perspective view of a third embodiment of the depression preventing means 200 applied to the lawn protection mat according to the present invention.

The depression preventing means 200 applied to the present invention, it is preferable that the groove 210 is formed on the bottom surface so as not to slide in the copper wire direction of the user or moving body.

In general, when the grass protection mat is installed in a place where a constant copper wire direction is designated, such as a golf course, the groove 210 may be pushed in the copper wire direction as the movement of the user or the moving object is repeated to one side. In order to more effectively prevent the slip in the direction, as shown in Figure 6 it is preferably formed long in the direction crossing the direction of the user.

In this case, the groove 210 may be formed to be inclined sidewalls in a direction wider toward the inlet side, so that the soil is filled in the inside more effectively to prevent slipping, more preferably may be formed in a thread shape.

In addition, when the user or moving body is installed in a place where the movement direction is not constant, the groove 210 is radially formed as shown in FIG. 7 so as not to slide in any direction as well as the movement direction, or in FIG. 8. As shown, it may be formed in an octagonal groove shape. In this case, the shape of the groove 210 may be formed in various polygonal or circular shapes such as triangle, square, hexagon, etc. as well as the octagonal shape shown in FIG. 8.

9 and 10 are plan views showing a direction in which the shock absorbing blade 400 is bent in accordance with the installation direction of the grass protection mat according to the present invention.

Since the shock absorbing blade 400 applied to the present invention is formed to have a width in the longitudinal direction of the body part 100, the shock absorbing blade 400 is bent only in a direction perpendicular to the longitudinal direction of the body part 100, and the copper line of the user or the moving object is constant. When limited to this, the buffer blade 400 may be broken as the bending phenomenon is repeated several times. In particular, when the copper wire direction of the user or the moving object coincides with the direction in which the shock absorbing blade 400 is bent, since the loads are all transmitted in the direction in which the shock absorbing blade 400 is bent, the shock absorbing blade 400 may be more easily damaged. There is.

That is, as shown in FIG. 9, when one side of the body part 100 is disposed at a right angle with the copper line direction, the cushioning blade 400 coupled to the upper and lower sides of the body part 100 is in the same direction as the bending direction. There is a risk of breakage more easily.

Therefore, as shown in FIG. 10, the body portion 100 is preferably arranged such that the bending direction of any one of the shock absorbing blades 400 does not coincide with the copper wire direction. When the shock absorbing blade 400 is configured to be bent in the direction crossing the copper wire as described above, the shock absorbing blade 400 is bent while sliding with the user or the moving object, so the angle of bending is reduced, thereby causing a risk of damage. Is reduced.

While the invention has been shown and described in connection with specific embodiments so far, it will be appreciated that various changes and modifications can be made in the art without departing from the spirit or scope of the invention as set forth in the claims below. Those of ordinary skill will want to know easily.

The grass protection mat according to the present invention can be used for a long time because the soil is not recessed even in a soft place, and can support a larger downward load without increasing the horizontal area of the sinking prevention means. There is an advantage that the risk of breakage is reduced.
