Description

  The present invention relates to a structure for connecting schemat or artificial turf, and more specifically, it is easy to connect and separate a plurality of schemats or artificial turf, and the connection state during use is stable. It is related to the connecting structure of the schemat or the artificial turf.

  The present invention relates to a schemat in which the work of connecting and separating the schemats is easy and the connection state during use is stable, and further, natural skiing by skiing and snowboarding can be obtained. It is about schemat that can be.

  Conventionally, as a connecting structure between unit mats such as schemat or artificial turf, a male connecting portion or a male engaging portion and a female connecting portion or a female engaging portion are provided on the side portions of adjacent unit mats, There has been proposed a structure in which unit mats are forcibly connected to each other by using elastic deformation by strongly pressing each other (see Patent Document 1 and Patent Document 2).

  However, in the conventional connecting structure between unit mats, a plurality of male connecting portions or male engaging portions and female connecting portions or female engaging portions provided for each unit mat are strongly pressed against each other and connected. There is a problem that it takes a lot of work to perform, and there is a problem that it takes a great force or a tool is required to separate unit mats once connected.

  In order to alleviate the above problem, it is conceivable to reduce the number of connecting portions provided in the unit mat, but in that case, since the load concentrates on each connecting portion, it is necessary to increase the strength of the connecting portion, Eventually, there arises a problem that the connecting work and the separating work are troublesome, and there is a problem that the followability to the uneven shape at the place where the mat is laid is deteriorated.

  Therefore, if the connection strength of the connection part is reduced without reducing the number of connection parts, the burden of the connection work is reduced, but the connection state between the unit mats becomes weak, and in the case of a schemat laid on the slope, it is snowy. The problem of not being able to sufficiently withstand the weight of the vehicle, or being unable to sufficiently withstand the vertical or lateral force applied to the unit mat by the load or friction applied by the skier.

  In addition, in the conventional schemat, if you slide on it with little or no snow, you can feel the natural gritty feel, or the frictional resistance is too large or too small to slide on the snow. I couldn't get a feel.

  In particular, since skis and snowboards differ in the action of load and frictional force applied to the schemat during skiing, the unit mats are connected to each other so that both skiers and snowboarders can obtain a natural skiing condition that is satisfactory. There was no schemat.

  Next, a description will be given of the connecting portions provided on the edge portions 11 and 12 of the schemat 10 of the present embodiment. The schemat 10 shown on the left side in FIG. A first engaging protrusion 1 formed in a columnar shape is provided on the edge portion 11 in the vertical direction.

  On the other hand, the schemat 10 shown on the right side in FIG. 1 includes, as a second unit mat, an engagement hole 2 into which the first engagement protrusion 1 can be inserted from the vertical direction at the edge 12 thereof. ing. And the 1st connector A is comprised from said 1st engagement protrusion 1 and the engagement hole 2, and the relative movement and engagement hole in the horizontal direction of the schemats 10 are connected at the time of connection of the schemats 10. The downward relative movement of the schemat 10 having 2 is regulated.

  Further, a second engagement protrusion 3 formed in a horizontal direction is provided on the edge portion 12 of the schemat 10 provided with the engagement hole 2 (shown on the right side in FIG. 1). It is formed on the side of the engagement hole 2.

  On the other hand, the lower surface of the edge portion 11 of the schemat 10 (shown on the left side in FIG. 1) provided with the first engagement protrusion 1 is formed at the tip of the second engagement protrusion 3. A locking surface 5 that abuts the provided locking upper surface 4 is provided. A second connector B is composed of the second engaging protrusion 3 (more precisely, the locking upper surface 4) and the locking surface 5.

  As shown in FIG. 4, the second engagement protrusion 3 includes the engagement upper surface 4 on the distal end side thereof, and an engagement end surface 6 provided in the vertical direction on the rear surface on the proximal end side. It is formed in an L-shape, and is configured such that a gap G is generated between the locking upper surface 4 and the locking surface 5 of the other unit mat 10 when both unit mats (schottts) 10 are connected. Has been.

  In the state where the gap G is maintained, even if both the unit mats 10 are to be rotated relative to each other, the locking end surface 6 is provided on the edge portion 11 of the other unit mat 10. , The relative rotation of both unit mats 10 is prevented, and the united state of both unit mats 10 can be maintained.

  Further, the rotation regulating end surface 7 and the upper surface 7a of the edge portion 11 constituting the rotation regulating end surface 7 are connected to each other by the second connector B when the schemats 10 are connected to each other. The relative movement in the horizontal direction and the relative movement in the vertical direction of the schemat 10 provided with the second engagement protrusion 3 can be restricted.

  On the other hand, in the state where the locking upper surface 4 is brought into contact with the locking surface 5 of the other unit mat 10 by slightly lifting the edge 12 so as to eliminate the gap G, the engagement The stop end surface 6 does not contact the rotation regulating end surface 7 of the other unit mat 10, the relative rotation of both unit mats 10 is allowed, and the connected state of both unit mats 10 can be released.

  The outline of the dimensions of the connecting portion in the connected state of the schemat 10 employed in the first embodiment to enable the above configuration will be described. The size of the gap G is 1 mm, the locking end surface 6 and the rotation regulating end surface. 7 is set to 1.5 mm, the shortest distance between the locking surface 5 and the rotation restricting end surface 7 at the edge 11 is set to 5.1 mm, and the second engaging projection 3 is engaged. The distance between the rear end portion of the stop surface 4 and the lower end portion of the locking end surface 6 is set to 3.7 mm.

  Note that when the two unit mats 10 are relatively rotated, the engagement holes 2 formed in the edge portion 12 of the schemat 10 are both set so that the relative rotation of both unit mats 10 is smoothly allowed. Although it is a long hole extending in the rotation direction of the unit mat 10 (direction perpendicular to the edge portion 12), it may be implemented as a truncated cone hole that expands downward (on the other unit mat side) In this case, the connection state between the unit mats 10 when the first engagement protrusion 1 and the engagement hole 2 are coupled becomes stronger.

  That is, the shape of the engagement hole 2 is not limited as long as the first engagement protrusion 1 is formed so as not to hinder the relative rotation of both unit mats 10. The upper end portion is circular and the lower end side is the unit mat 10. It may be a long hole extending in the rotation direction.

  Further, when connecting the two connectors A and B to each other, the respective parts are not particularly forcedly deformed, and it does not take time and effort to press the connecting part when connecting the unit mats. A large number of pairs of connectors A and B can be formed adjacent to each other on the edge portions 11 and 12 (alternately arranged in this embodiment), and the connection strength between the unit mats and the follow-up to the installation surface can be achieved. The property can be made excellent.

  Therefore, even when the installation surface of the schemat 10 is not flat, the tight connection state of the edge portions 11 and 12 by the connectors A and B is maintained, so that the schemat 10 has an uneven shape on the installation surface. It follows flexibly and the connection state is stable, and a suitable sliding state by skiing or snowboarding can be obtained.

  Further, when the schemat 10 according to the first embodiment is connected to another schemat 10, the annular portion 2a around the engagement hole 2 formed in the edge portion 12 has the first engagement. It is formed in a shape that matches the shape of the arcuate recess 11 a of the edge 11 around the protrusion 1.

  Further, by forming the shape of the base portion 3 a of the second engaging protrusion 3 into a shape that matches the shape of the rectangular recess 11 b of the edge portion 11 of the other schemat 10, the edge portion of the schemat 10 The connection strength between 11 and 12 and the followability to the installation surface can be improved, and the connecting portion is smooth, so that the appearance form is not impaired, and the skiing performance by skiing or snowboarding can be further improved. it can.

  Moreover, since the shape of the edge parts 11 and 12 was matched at the time of connection as above (refer FIG.1 and FIG.5), it is also possible to make the arc-shaped recessed part 11a or the rectangular recessed part 11b act as a rotation control end surface. is there.

  Furthermore, the engagement protrusion 1 and the engagement hole 2 of the first embodiment are arranged at the intersection of the mesh where the rod-shaped protrusion 15 is not formed, and further, the rod-shaped protrusion 15 on the base of the second engagement protrusion 3. As a result, the mesh pattern formed by the rod-shaped protrusions 15 on the upper surface of the schemat 10 that is connected and installed in a large number is not disturbed.

  Therefore, the schemat 10 of the present embodiment 1 has a natural sliding performance due to the rod-like protrusions 15. Further, the schemat 10 of the present embodiment preferably has viscoelasticity such as polyethylene and EVA as a whole. It is molded in one piece with a synthetic resin and blended with a lubricant and weathering agent, so that smooth sliding performance can be obtained even when there is no snow, and it can withstand long-term use at a ski resort. It is like that.

  When connecting the edge portions 11 and 12 of the two schemats 10 configured as described above to each other, the first engagement protrusions 1 are inserted into the engagement holes 2 so that both the schemats 10 are connected. When connecting to each other, as shown in FIGS. 6A to 6E, the upper surface 4 of the second engagement projection 3 is inclined upward (in this embodiment, the other mat is about 40 to 45). From the side of the edge portion 11 of the schemat 10 provided with the locking surface 5, and then the two schemats 10 are relatively rotated to align the upper surfaces of the two schemats 10. Thus, the two schemats 10 are connected to each other.

  In this connected state, (1) the second engaging protrusion 3 facing the rectangular recess 11b and (2) the front surface of the rectangular recess 11b between the locking end surface 6 and the rotation restricting end surface 7. Since a slight gap is formed between the front surfaces of the unit mats 10, there is no problem in the above connecting operation and the following separating operation between the unit mats 10.

  In order to release and separate the connection state of the above-mentioned schemats 10, the gap G is naturally eliminated by lifting up so as to cause one of the schemats 10. Therefore, the reverse procedure of the above-described connection operation is performed. Thus, the both schemats 10 may be simply rotated relative to each other.

  Therefore, in the schemat 10 that employs the connection structure of the present invention, the edge portions 11 and 12 in the connecting operation and the separating operation of the first and second connectors A and B provided on the edge portions 11 and 12 are performed. It is not necessary to forcefully deform the connectors A and B by pressing down or using a tool, and these operations can be easily and easily performed without requiring labor and effort for connecting and separating a large number of schemats 10. Can be done quickly.

Next, the connection structure by the connector C formed in the edge portions 13 and 14 on the short side of the schemat 10 will be described with reference to FIGS.
In the connection structure of the schemat 10 according to the present invention, the unit mats are elastically deformed by overlapping the unit mats in the vertical direction on the other edge portions 13 and 14 where the connectors A and B are not formed. A third connector C that can be combined is provided.

The edge 13 corresponding to the upper side of the locking surface 5 is an inclined surface 13c cut in a taper shape, which is different from the case of both the connectors A and B.

  Accordingly, by pressing the second engaging protrusion 3 from above the inclined surface 13c (above the locking surface 5), the tip end portion 3c of the second engaging protrusion 3 is elastically deformed to be below the locking surface 5. Further, the engagement state between the locking upper surface 4 and the locking surface 5 is weaker than that in the case of the connector B, and the unit mat 10 is pulled up to rotate the two relative to each other. The connected state by the third connector C can be forcibly released relatively easily.

  In particular, in the schemat 10 of the present embodiment, there is no need to press the connecting portion on the edge portions 11 and 12 on the long side, and connectors A and B suitable for quick connecting work are provided. Since the connector C that is required to press the connecting portion to the edge portions 13 and 14 is provided, a configuration advantageous in terms of work efficiency in which a large number of schemats 10 are laid side by side in a wide range like a slope. It has become.

Therefore, the sliding surface constituted by the connected schemat 10 can be made uniform as a whole.

  As described above, the schemat 10 according to the present embodiment employs the above-described connection structure using the connectors A, B, and C in the edge portions 11 to 14. It can be firmly connected to provide excellent followability to the installation surface and can be laid cleanly, providing a natural gliding feeling for both skiing and snowboarding. Furthermore, the rod-shaped protrusions 15 are arranged in a mesh pattern. The snow retaining space 16 and the upper surface 16a of the schemat 10 in the space portion that avoids geothermal heat have excellent snow retaining power.
