Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a simple rail that can be easily installed and is suitable for use as a twin rail buried in the rough and fairways of a golf course, for example.

BACKGROUND ART Conventionally, golf bag transport carts installed at golf courses, for example, have been transported while straddling a straddle rail laid along the rough of the golf course.

However, since such rail structures are installed higher than the ground or buried in U-shaped grooves, they are not aesthetically pleasing even in rough areas of golf courses, and it is even more difficult to install them on fairways. This will significantly impede the Moreover, when the player has to pick up the ball in the opposite direction to the direction in which the rail is installed, there is a problem in that walking time is wasted and other players are also inconvenienced.

In view of the above, the present invention minimizes the walking distance of players by laying it in the center of the fairway of a golf course, and also improves the working conditions of the golf course without causing any hindrance. The main purpose of the present invention is to propose a method for laying this type of simple rail that does not become a hindrance to maintenance vehicles and workers, and also does not damage the overall scenery of the golf course.

An embodiment of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a sectional view showing an example of a pile structure suitable for use in the method of the present invention. Reference numeral 1 indicates a synthetic resin rail, which has legs 3 extending downward from both ends of a flat base 2. The legs 3 are formed with serrations 5 on the outer and inner surfaces so that they do not bulge up after being press-fitted into the ground, and the insides of both legs 3 are engaged with stakes 6 to prevent the rail 1 from floating due to frost, etc. that occurs in winter. An inner claw 7 is provided in the extending direction of the rail 1. The rail 1 is preferably made of a strong polymer of polypropylene and high-molecular polyethylene, both of which have good weather resistance. Further, when manufacturing the rail 1, the raw resin can be directly colored.

The stake 6 is made by welding a round member 6b having a square head 6a that engages with the inner claw 7 of the rail 1 to an L-shaped member 9. The L-shaped member 9 has a plurality of holes 9a formed therein so that earth and sand bite into it and prevent it from falling out when driven in with a hammer or the like. The width dimension _l1 of the head 6a is set to approximately match the inner distance between the legs 3, and is set larger than the distance _l2 between the inner claws 7.

Next, to explain an example of the method of the present invention,
First, in order to lay the rail 1 on the lawn surface, as shown in FIG. 2, first, the heads of the stakes 6 are driven directly onto the rail installation line at regular intervals using a pile hammer or the like until the shapes are buried. At that time, if the ground is not flat or if the distance between the twin rails is to be maintained accurately, as shown in Figure 3, a plate with rectangular holes for inserting the shape material at positions that match the distance between the twin rails on the plane is used. This is done using a rail laying jig 10 of the shape. This jig 10 is provided with a guide portion 14 to maintain accurate spacing between the rectangular holes 11, and a guide portion 15 to maintain the stake 6 at right angles. The guide portion 14 is made of a thick plate, and a rectangular hole 11 is bored in the center of the guide portion 14 . 16 indicates a handle for carrying.

Therefore, the jig 10 is placed so that its longitudinal direction is perpendicular to the rail installation line, and the shapes 9 are inserted into the rectangular holes 11 on both sides and cast until they are buried in the ground. Rails 1 are placed on piles 6 placed at meter intervals.
By placing the pile and pressing it from the top of the rail 1 with a pile hammer or the like, both legs 3 of the rail 1 are slightly expanded and the head 6a of the pile 6 is held between the legs 3. You will be stopped from leaving. Then, the rail 1 is driven into the ground 16 from the top using the rail driving tool 15 to complete the process.

Incidentally, the rail 1 between the piles 6 is similarly finished using the rail driving tool 15 while moving sequentially so as to be flush with the ground.

As shown in FIG. 4, the rail driving tool has a guide 19 that is slightly wider than the width of the rail 1 at the base 18, a hammer receiving part 20 is formed at the upper part, and the base 18 is moved in the direction of the rail 1. In order to facilitate movement, a curved surface 18 is formed in the front-rear direction of the rail 1.

As described above, according to the present invention, a pile consisting of an angular head and a section to be buried in the ground is fitted into a rail laying jig set at the rail spacing and driven into the pile, Before the pile reaches the ground, a synthetic resin rail with an inner claw that engages with the head of the pile is engaged and driven into the pile, so that the upper surface of the rail is flush with the ground and on the grass surface. Since the structure is configured to drive the rails to a lower position, it can be laid in a much shorter period of time compared to the conventional method of laying railroad ties and then laying the rails again. This has the effect of shortening the rail installation period.

Moreover, the rails can be installed almost flush with the ground, so even when the rails are installed in the center of the fairway of a golf course, they do not give the appearance of protruding into the grass surface.
By applying the same color or resin coloring to the surface of the rail, there is an effect that the scenery of the entire golf course is not obstructed. Furthermore, it is possible to prevent the rail from floating due to frost damage that occurs in winter.

Further, according to the present invention, even when it is necessary to walk from the position of the golf cart on the twin rails laid in the center of the fairway in the left and right rough directions, the player can minimize the walking distance.
