Abstract

PURPOSE:To obtain a superior workability of putting together and dismantling of a lane, and to prevent from the contamination and the damage to an indoor facility, and the hindrance to other games by placing a plurality of square board bodies with stiffness in order, and forming into one united body by connecting the whole. CONSTITUTION:On the upper surface of a stiff board 2 of a hard urethane resin reinforced by mixing glass fiber, surface layer material 3 made from urethane resin with satin surface is laminated with adhesive, along the long sides of both sides of which banking parts 4 are provided. The lower surface of outside of this banking part 4 is a cutout part 5 of square of section which is reinforced by attaching angle material 6. On a rising surface near both ends of the cutout part 5 of the board body 1, a male fitting 7 or a female fitting 8 as a connecting clamping fitting is attached. The board bodies 1, 1 placed in order with short pieces abutted are fastened and connected by engaging a connecting lever 9 of the male fitting 7 to the female fitting 8 and pushing down a lever 10, and are released the connection by pushing up the lever 10.

Description

[Detailed description of the invention] [Industrial application field] This invention relates to lanes for tug-of-war competitions.

[Problem to be solved by the invention]

Conventionally, when tug-of-war competitions are held indoors such as in gymnasiums, the lanes are generally made of thick pile fabric in order to provide appropriate softness, friction, etc. to the lanes. In such lanes, the tension of the rope during competition acts on the fabric through the athletes' feet, so if the fabric is simply laid down, the fabric will move and interfere with the competition. Therefore, conventionally, the back side of the fabric and the floor surface were fixed using double-sided adhesive tape or the like. For this reason, it took time and effort to lay and remove the textiles, and there were many cases in which sticky substances adhered to the textiles, staining the floor surface, and interfering with other competitions.

In addition, the lanes are approximately 28 meters long at most, and since the lanes are formed from continuous sheets of fabric, the fabrics are heavy and large and require a great deal of effort to transport, lay, and remove. There were drawbacks.

This invention was made in view of the above circumstances. The purpose is to propose a lane for tug-of-war competitions that has excellent workability when assembling and dismantling the lane, and that does not contaminate or damage indoor facilities such as gymnasiums or cause problems in other sports.

[Means and Embodiments for Solving the Problems] This tug-of-war competition lane is characterized by having a plurality of rectangular rigid plates arranged side by side and connected together as a whole.

Figure 1 shows the lane of the example, and the width is 1.10.
0 ms, 14 rectangular plates l with a length of 2,000 mm,
Lay out the short pieces and lay them out. 1. The lanes were connected together to form a lane with a width of 1,100 *■ and a length of 28 m.

As shown in Figure 2, the plate 1 is a rigid substrate 2 (thickness 24 m) made of highly rigid hard urethane resin reinforced with glass fiber.
), a surface material 3 (thickness 5 mm) made of urethane resin with a matte surface is adhesively laminated on the top surface, and raised portions 4 (width W LOOw, height 875 mm) are formed along the long sides on both sides.
is set & j. The outer lower surface of this embankment portion 4 forms a cutout portion 5 having a rectangular cross section, and an angle member 6 is attached to the cutout portion 5 for reinforcement.

. A male fitting 7 or a female fitting 8 of a connecting fastener shown in FIG. 3 is attached to the rising surfaces of the plate body 1 near both ends of the notch 5. As shown in FIG. 4, the plate body 1.1, which is made up of short pieces butted and arranged side by side, is connected by locking the connecting rod 9 of the male metal fitting 7 to the female metal fitting 8, pressing down the lever 10, and tightening the lever 10. Release the push-up connection. Note that both the female and male fittings of the connecting fastener are sized to fit within the notch 5 and do not protrude from the bottom or side surface of the plate 1.

The board used in this lane must have the rigidity to not buckle even when a horizontal compressive force commensurate with the tension applied to the rope during competition is applied when it is laid on a horizontal base. . In addition, in order to convert the athlete's force into rope tensile force using the sole of the shoe as a fulcrum, the plate surface must have an appropriate coefficient of friction and softness.For this reason, in the above embodiment, the rigidity is The above two requirements were satisfied by laminating a high substrate and a surface material to form a plate. As such a substrate, in addition to the fiber-reinforced synthetic resin board described above, various materials such as a synthetic resin-reinforced wood board, plywood, or a laminate thereof can be used. At this time, the thickness is adjusted depending on the rigidity of the substrate used to provide strength that will not buckle.

[For production]

This invention consists of the above configuration. The force that acts on the lane in a tug-of-war competition is an opposing horizontal force from both sides of the lane toward the center of the lane, but since this lane is made up of multiple highly rigid boards connected and integrated, the seats of the boards are The deformation of the lane due to bending does not occur, and the forces that act during competition do not act outside the lane, so the lane does not move relative to the underlying surface.

To assemble or dismantle this lane, you can install or remove plates in units, connect them with metal fittings, handle large and heavy fabrics, or use adhesive tape, etc. There is no need to stick to the underlying surface, and workability is excellent, and there is no risk of contaminating the underlying surface or interfering with other sports.

In addition, like the lane in the example, raised parts are provided on both side edges,
It is preferable to provide a notch in the lower surface and store the connecting fastener so that the metal fittings do not protrude from the side edge. Furthermore, when installing or removing the plate, the plate can be raised by inserting the tip of a finger into the notch, making it easy to handle.

〔Effect of the invention〕

This invention is as described above, and this lane for tug-of-war competitions: ■ satisfies the requirements for conducting tug-of-war competitions; at the same time; ■ has excellent workability in assembly and disassembly; and ■ prevents contamination of the floor of the gymnasium. It will not be damaged and become a hindrance to other sports, and ■The boards can be stored in a stack, so they can be stored in a small space.
