Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to the structure of a track block for vehicles running on a lawn such as a golf course.

[Prior Art] Recently, golf courses have been using transport vehicles to transport cargo such as golf bags and personnel such as players and players, and the portions where these transport vehicles travel relatively frequently are used as running paths for the vehicles. . Conventionally, the structure of this running road was paved with Alfa Alto or concrete along the running line, but with this structure, the paved road was relatively wide, exceeding the vehicle width of the above-mentioned transport vehicle. Therefore, there was a problem that the scenery of the lawn area deteriorated.

Therefore, as a running road structure that can solve the problem of the deterioration of the scenery mentioned above,
There is a method described in Publication No. 27002, in which a trench slightly wider than the transport vehicle is excavated along the travel line, a roadbed is constructed on this, and a concrete foundation is placed on the roadbed along the wheel trajectory. The concrete rail unit was connected and fixed on the foundation with mortar, and then the groove around the rail was backfilled.

[The problem that the idea attempts to solve]

However, in the conventional structure described in this publication, only the rail unit is exposed from the lawn surface, so problems such as deterioration of the lawn landscape can be reduced. However, with this conventional structure, as time passes after construction, soil for turf cultivation or dead grass after lawn mowing tends to accumulate on the rails, which causes trouble for vehicles when running.

This invention was made in view of the problems of the conventional structure described above, and an object of the present invention is to provide a track block structure for vehicles running on lawns that can prevent deterioration of the landscape of lawns and avoid troubles in running the vehicles. It is an object.

[Means to solve the problem]

The track block structure for a lawn vehicle according to this invention includes a plurality of track members each having a large number of protrusions on the upper surface thereof, which are installed between adjacent sleepers so that the upper ends of the protrusions protrude from the lawn surface. Furthermore, the plurality of protrusions are configured such that their heights are sequentially increased from the center of the track material toward both left and right sides in a plane perpendicular to the running direction, and the heights of the plurality of protrusions are arranged so that the heights of the protrusions increase sequentially from the center of the track material toward both left and right sides. A plate-shaped wall member having approximately the same height as the height of the protrusion connecting both protrusions is provided integrally with the protrusions between adjacent protrusions in the protrusion row in the direction.

[Effect]

In this invention, a plurality of track members having a large number of protrusions on their upper surfaces are installed between adjacent sleepers so that the upper ends of the protrusions protrude from the grass ground surface, so that the grass does not fall within the track of the vehicle. Can be made into vegetation. In addition, the height of the protrusions on the track material increases from the center of the track material toward both left and right sides in a plane perpendicular to the running direction, so each wheel of a running vehicle automatically moves to each track. This allows the vehicle to travel in the center of the road, thereby preventing the wheels from coming off the road on slopes or curves.
Furthermore, a plate-like wall member having approximately the same height as the projections is provided integrally with the projections between adjacent projections in the row of projections in the vehicle width direction of the traveling vehicle, which are separated by a predetermined distance.
It is possible to prevent the part buried in the sloped land tilted in the running direction of the vehicle from becoming a waterway where surface water of the lawn concentrates, thereby preventing the soil surrounding the large number of protrusions from being washed away.

〔Example〕

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

Figures 1 to 11 are for explaining one embodiment of the present invention, and a vehicle running on a track having the structure of this embodiment has two rear left and right rear sections, which are not shown. It is a tricycle-type vehicle with left and right rear wheels and a double-tire front wheel located at the center of the front.

4 and 5 are a plan view and a perspective view, respectively, showing the resin track block of this embodiment.
Figures a to f, Figures 2 a to f, and Figures 3 a to f are views showing the front wheel track material, the rear wheel track material, and the sleeper material, respectively, which constitute the track block. Here, in each figure, a is a side view, b is a top view, c is a bottom view, d is a cross-sectional view taken along line D-D in figure b, e is a cross-sectional view taken along line E-E in figure b, and f is F in figure b. -F line sectional view.

In the figure, 5 is a track block in the shape of a planar isosceles trapezoid, 7 is the front, rear, and middle thin sleepers that are reinforcements for the left, right legs, and center of the trapezoid;
These sleeper timbers consist of thin rod-shaped bodies with a generally inverted convex cross section. The narrow part 7d on the lower side of this pillow wood 7
serves as a reinforcing portion of the pillow timber 7. Further, connecting seats 7a and 7b are integrally formed on the left, right (Fig. 3 a to c) and center upper surfaces of the sleeper 7, and connecting holes 7c are bored in the connecting seats 7a and 7b. ,
The sleepers 7 are buried in the lawn 11a in a direction perpendicular to the traveling direction of the vehicle and parallel to the traveling direction.

Between the left and right connecting seats 7a of the front and rear sleepers 7 are the upper and lower bases of the trapezoid, and the first and second seats are slightly wider than the left and right rear wheels of the vehicle. 2
Rear wheel track members 28a, 28b are installed, and a front wheel track member 9, which is slightly wider than the double tire type front wheels, is installed between the central connecting seat 7b. Connector 10 such as a bolt or nut is connected to both ends and the center of 9.
are connected to the connecting seats 7a, 7b.

Further, the rear wheel raceway members 28a, 28b and the front wheel raceway member 9 are rod-shaped bodies having a T-shaped cross section and a horizontally elongated isosceles trapezoidal shape in plan, as shown in FIGS. The wheel rests 8a, 9a, which are the upper sides, are inclined so that both sides are slightly higher than the center, and each of the wheel rests 8a, 9a has a large number of truncated conical protrusions 8c, 9c over the entire surface. is installed protrudingly,
Moreover, the heights of these protrusions themselves increase successively from the center toward both left and right sides in a plane perpendicular to the travel direction. In addition, each track material 28a, 28b, 9
Between adjacent protrusions in a row of protrusions in the vehicle width direction separated by a predetermined distance, there are soil flow stoppers 8e and 9e, which are wall members having approximately the same height as the protrusion height connecting both protrusions.
is provided, which is formed integrally with each of the above-mentioned protrusions. Further, oval-shaped connecting holes 8f, 9f, which are long in the track direction, are formed in the connecting portions at both ends and the center of the track members 28a, 28b, and 9. Furthermore, guide material grooves 9d for mounting guide materials are recessed at both ends of the front wheel raceway material 9 and at the center of the connecting portion at the center. Further, the buried portions 8b, 9b, which are the vertical sides of the track materials 28a, 28b, 9, are the placement portions 8a, 9a.
This is a reinforcing part to prevent deformation. Each track material 28a, 28b, 9 is connected to the lawn 11.
The upper ends of the projections 8c and 9c are exposed from the surface of the lawn 11a.

Next, the pillow timber 7, the track materials 28a, 28b, 9
A method for burying the grass in the lawn 11a will be explained.

FIG. 6 shows a golf course in which a running path has been created using the track block 35 of this embodiment, in which 11 is a fairway, 12 is a playing ground, and 1
3 is a green, 14 is a bunker, 15 is a management road around the course, and 16 is a rough road.
It is created by traversing the area.

The above-mentioned burying method will be explained using FIGS. 7 to 11. (1) First, a running line of the running vehicle is set, and the width of the running track of the running vehicle is about the same as the width of the vehicle, that is, the track block 5. A groove 17 is formed by peeling off the entire surface of the lawn 11a corresponding to approximately the same width and excavating the exposed soil of the roadbed shallowly to place the track block 5.
A is formed, and the depth of the roadbed of the groove 17a is regulated and compacted to form a foundation roadbed 17b (see FIGS. 7a and 7b).

(2) Next, sleepers 7 are arranged on the foundation roadbed 17b at equal intervals in a direction substantially perpendicular to the traveling direction of the traveling vehicle, that is, approximately along the multiple wheel trajectories created by one traveling vehicle. A sleeper line that intersects at equal intervals is set, and the sleeper 7 is arranged along this sleeper line, and then the first and second rear sleepers are placed on the sleeper 7 along the travel trajectory of the rear and front wheels of the vehicle. The wheel raceway members 28a, 28b and the front wheel raceway member 9 are arranged (see FIGS. 7c and 7d).

Here, the traveling path 17 has a straight road portion and a curved road portion, but in the track block of the structure of this embodiment, in the work of arranging track materials for the straight road portion, as shown in Fig. 8, both sides of the straight road are each,
The shorter first rear wheel raceway material 28a and the longer second rear wheel raceway material 28b are arranged alternately, and when the raceway material is placed on a curved road section, as shown in FIG. The short first one on the inside of the road
A second track member 28b, which is longer, is successively arranged on the outside of the track member 28a.

Thereafter, the connecting portions of the track members 28a, 28b, 9 and the connecting seats 7a, 7b of the sleeper 7 are connected using connectors 10 such as bolts and nuts.

(3) Finally, backfill soil up to the height of the upper surface of the track material placed on the foundation subgrade 17b (Fig. 7e), and fill the entire surface including the upper surface of the track material or the soil excluding the track material portion. If grass is pasted on the sections (FIG. 7f), the track materials 28a, 28b,
The protrusions 8c and 9c of 9 are exposed from the lawn (FIGS. 10 and 11), and in this way a running path 17 is formed along the running line.

As described above, in this embodiment, since the lawn in the area that will become the running path of the vehicle is completely removed, the lawn removal work does not have to be carried out for each wheel track of the vehicle, but can be done at once. Moreover, there is no need to cut the grass roots before burying the track materials and sleepers, and since the excavation depth of the track arrangement groove 17a is shallow, the amount of soil for backfilling is small.
The workability of burying sleeper timbers can be improved.

Further, in the vehicle running path of this embodiment, since the track block 5 has an isosceles trapezoidal shape, both straight road sections and curved road sections can be easily and reliably constructed. In addition, in this track block 5, since the sleepers 7 are arranged not only at both ends of the track members 28a, 28b, and 9 but also in the center, the wheel mounting portions 8a, 9a and reinforcing portions of the track members are made thinner. Moreover, since the sleeper wood 7 itself is thin, it is possible to significantly reduce the weight. Furthermore, each of the above-mentioned raceway materials 28a, 28
In cases b and 9, the protrusions 8c and 9c are gradually higher from the center toward both sides, so that the running path 17
It is possible to prevent wheels from coming off at sideways sloped sections and curved sections, and the ground contact area of the wheels is increased, thereby improving braking performance. Moreover, a wall member 8 having the same height as both protrusions is provided between predetermined adjacent protrusions.
Since the grooves e and 9e are formed, they act as a stopper for the soil to flow and prevent the soil on the track material from flowing away due to the water flowing on the surface of the lawn.

Further, after construction, the only exposed objects are the protrusions 8c and 9c, which are hardly visible to the player and therefore hardly spoil the landscape of the lawn. Furthermore, the connection hole 8 of the connection part of the raceway members 28a, 28b, 9
Since f and 9f have an oval shape, if the raceway material expands during high temperatures in summer, this expansion can be absorbed by the connection holes 8f and 9f, and furthermore, if the raceway material 28a, 28b, 9, etc. are damaged. In this case, the track material can be replaced by removing the connector 10, and repair work can also be facilitated.

In addition, in the above embodiment, the case where the track material laying work is performed after the sleeper timber laying work is performed is shown, but these works may be performed at the same time.In other words, one of the front and rear sleeper timbers 7 and The track blocks 5 may be temporarily assembled by assembling the track members 28a, 28b, 9 to the central sleeper 7, and this temporarily assembled track block may be placed and connected within the foundation subgrade 17b; in this case. Work time can be significantly reduced.

Furthermore, in the above embodiment, the case of a traveling vehicle with a double tire type front wheel was explained, but the present invention can of course be applied to a traveling road for a traveling vehicle with a single tire type front wheel, and in this case, the front wheel track material is Just make it a little wider than the tire-shaped front wheel. Furthermore, the present invention can also be applied to a four-wheeled vehicle running track where four running trajectories occur; in this case, two track materials for the front wheels and two track materials for the rear wheels are provided,
Further, the guiding material groove may be recessed in the center of each sleeper.

Furthermore, in each of the above-mentioned embodiments, a case was explained in which a running path for vehicles was created at an existing golf course.
The basic construction method of the present invention can also be applied to creating a driving path on a golf course under construction, that is, a course without grass. A shallow part of the ground corresponding to the width of the running vehicle is excavated, and the course is then compacted, the sleepers and track materials are laid, the sleepers and track materials are connected, and the soil is backfilled. At the time of turfing, it is sufficient to turf this part of the running path as well. In this case, the same effects as those of the above embodiments can be obtained except for the above-mentioned lawn removal work.

[Effect of idea]

As described above, according to the track block structure for lawn vehicles according to the present invention, between adjacent sleepers,
A plurality of track members each having a large number of protrusions on the upper surface thereof are constructed so that the upper ends of the protrusions protrude from the grass ground surface, and the heights of the plurality of protrusions are placed on the track members in a plane perpendicular to the running direction. The height of the projections is increased from the center toward both the left and right sides, and between adjacent projections in the row of projections in the vehicle width direction of the traveling vehicle, there is provided a wall member of approximately the same height as the height of the projections. Since it is provided integrally with the protrusion, it is possible to prevent the wheels from coming off on horizontally sloped or curved sections of the running path, and it is also possible to prevent the soil on the track material from being washed away by running water on the lawn surface. This has the effect of reliably growing the lawn and preventing deterioration of the landscape of the lawn.
