Abstract

PURPOSE: To accurately clock the movement of a kite between predetermined courses where deviated gates are placed by the movement of the kite by attaching the almost lower end part of an elongated rod to the almost upper end part of a support in a freely revolvable manner and providing the elastic means connected to the lower end part of the rod and the support in order to usually hold the rod to an erected state. CONSTITUTION: A vertical rod 12 is connected to a pipe 10 at the position of the part 14 adjacent to the upper end part thereof in a freely revolvable manner. A cord 30 is fastened to the lower end part 18 of the rod 12 and the outer end part of the rod 20 before nuts 26, 28 and the lower end part of the rod 12 is elastically connected to the pipe 10. Further, in order to improve the visual display of the revolution of the rod 12, a tray 74 is provided so as to be adjacent to the lower end part of the rod 12. When yarn of a kite comes into contact with the upper end part of the rod 12 and the rod 12 is clockwise moved up to a dotted-line position, a clock device 72 is operated for start or stop. By this constitution, the movement of the kite biased by the movement of the kite between predetermined courses where gates are placed can be accurately clocked.

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a device which can be used as a race gate. More particularly, the present invention relates to a racing gate operated by a kite string of a horizontally moving kite.

[0002]

2. Description of the Related Art Kite racing competitions are gaining popularity. There is a form of kite that is often referred to as a delta-wing kite, which is the end of a pair of kite yarns, as opposed to the traditional form of kite being a single kite yarn. Attached to the section. When the triangle wing kite is in the air, two threads extend down to the ground, where they are held separately by the hands of the person operating the kite. Without needing to discuss the principles behind the movement of these two-thread kites, the skilled worker will make these kites perform individual adjustments to do what is not normally possible with conventional single-thread kites. be able to. For example, according to these triangular wing kites, after being released into the air, these kites can be moved horizontally at a high speed at which the kite moves in a very delicate state.

When these triangular wing kites are run at high speed in the horizontal direction, these kites are allowed to compete in various horizontal and vertical patterns, and the time required for each kite to cross a predetermined course is recorded. It has become a habit recently to do. Thus, there was a kite racing competition.

[0004]

Presently, the method of timing a kite passing through a given course relies on a stopwatch and a visual observation (evaluation) of when the kite starts and ends the course. As far as the inventor knows, there is no gate that can accurately time the movement of a kite between predetermined courses where the gate is placed, by the movement of the kite.

Therefore, it is an object of the present invention to provide a kite race gate capable of accurately timing the kite movement between a predetermined course on which the gate is placed, depending on the movement of the kite.

[0006]

SUMMARY OF THE INVENTION The kite racing gate comprises a substantially vertical tube which at its lower end supports the tube on the ground, preferably the gate moves from one position to another. It has means for supporting it by piercing so that it can. An elongated rod is rotatably mounted adjacent to the upper end of the tube such that the rod projects into the path of the moving kite, or more precisely the path of the moving thread of the kite. Has an upper end. The lower end of the rod is elastically attached to the tube below the pivot point, so that when the rod is rotated by the horizontal movement of the kite thread that hits the upper end of the rod, the kite string passes by. Later, the bar is designed to return to its upright position. An electric timer, like a stopwatch, is connected to the tube. A timer lead extends upwardly from the tube and one of the leads is electrically connected to a conductive sleeve provided on the rod. The other lead wire is electrically connected to the second conductive sleeve, and the second conductive sleeve has the first sleeve and the second sleeve when the rod is rotated in a predetermined rotation direction. It is provided on the tube at a position where it contacts the sleeve. The elastic means are preferably provided such that the rod is slightly offset from the vertical in order to prevent an unexpected contact between the two sleeves in the counter-rotating state.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now to FIG. 1, a kite race gate is shown as comprising a vertical strut or support from a tube 10 which may be made of metal or preferably plastic. Become. The vertical rod 12 is the pipe 10.
It is rotatably connected to the tube 10 at the number 14 adjacent to the upper end of the tube. The rod 12 is a hollow tube made of metal or preferably plastic and may be provided with a telescoping extension 16 so that the effective height of the rod 12 can be varied as desired. The lower end 18 of the rod 12 is elastically connected to the vertical pipe 10.

The threaded rod 20 is the lower end 1 of the rod 12.
Underneath 8, it extends outwardly at right angles to the tube 10. Nut 2
2, 24 hold the rod 20 firmly to the tube 10. A pair of nuts 26, 28 are received on the outer end of the rod 20. Bungee cord 3
0 is fastened to the lower end 18 of the rod 12 and to the outer ends of the rod 20 past the nuts 26, 28. Nuts 26, 2
8 can be moved inward along the rod 20 when it is desired to change the angle of the bungee cord 30 and thus of the rod 12. Bungee Code 30 if desired
A spring (not shown) can be used in place of In any case, the bungee cord elastically connects the lower end of the rod 12 to the tube 10, as described above. As shown in FIG. 1, the rod 12 is upright, but not in the exact vertical position, and is actually placed slightly counterclockwise to the vertical for reasons that will become apparent later. Has been done.

Next, a method of rotatably attaching the rod 12 to the tube 10 will be described in detail with reference to FIGS. 2, 3 and 4. Threaded bolts 32 are threaded through a pair of aligned holes (not shown) adjacent the upper end of tube 10. The shank of the bolt 32 extends forward, as best shown in FIG. A nut 34 holds the bolt 32 snugly on the tube 10. Another nut 36 is attached to the outer end of the bolt 32 and welded to the metal sleeve 38. A brass sleeve 40 is received in the sleeve 38 and extends above and below the sleeve 38. The rod 12 is tightly received within the sleeve 40.

Another bolt 42 is attached to the tube 10 under the bolt 32 and at a substantially right angle to the bolt 32. The bolt 42 is held in place on the tube 10 by a nut 44. A hollow T-joint 46 is attached to the outer end of the bolt 42 and is held in place by a pair of nuts 48,50. The T-shaped joint 46 has a right angle portion 52.
The right-angled portion 52 is internally threaded to receive the shaft portion 54 of the elongated bolt 56. A brass sleeve 58 is received in the bolt 56 and held in place by a nut 60. A locknut 62 holds the bolt 56 in place on the threaded portion 52 of the Tee fitting 46.

A pair of insulated leads 64, 66 connect the tube 10
1 through a hole 68 in the cap located at the upper end of the tube, extending to a position adjacent the bottom of the tube 10 and out there through a suitable opening (not shown), It is connected to a suitable timing device 72 shown schematically. Details of the timing device 72, ie the electrically operated stopwatch, are considered to be commonplace and will not be described in detail. However, it is only mentioned that when the brass sleeve 40 contacts the brass sleeve 58, the timing device 72 is activated for starting or stopping. This state occurs when the rod 12 moves clockwise to the dotted position shown in FIG. Such movement of the rod 12
When the kite thread contacts the upper end of the rod 12, it is caused by the thread moving from left to right.

A circular member or dish 74 is provided adjacent the lower end of the rod 12, as best shown in FIG. The dish 74 is preferably painted in a light color to improve the visual indication of the pivoting of the rod 12. Tube 10
The lower end of is received in a metal tube 76 which is connected to a nail 78. The lateral member 80 is fixed to the nail 78.
When it is desired to position the gate shown in FIG. 1 at a predetermined position on the ground, simply place a nail at a desired position and press down with a foot placed on the lateral member 80 so that the gate pierces the ground.

It is envisaged to use more than one gate in a kite race. That is, the kite activates multiple gates in series with its thread, then returns and reactivates some or all of the same gates. The gate shown in FIGS. 1-4 activates one timing device 72, even if the plate 74 provides a visual indication of when the gate is tilted.
When the kite is moved from the right side to the left side and the gate shown in FIG. 1 is hardened by the kite thread, the rod 12 simply moves further in the counterclockwise direction, and the brass sleeve 40 moves to the brass sleeve 58.
, And thus in this moving mode of the kite, the timing device 72 does not operate. However, the next time the gate of FIG. 1 is actuated by a kite moving from left to right, the timer 72 will be stopped, assuming the gate was rotated by the movement of a similar kite.

When the rod 12 is placed in the correct vertical position, the brass sleeve 40 contacts the brass sleeve 58 by the reverse rotation after the initial contact, and the timer 72
It was found that an error occurred in the operation of. Therefore,
The rod 20 is provided such that the rod 12 is positioned slightly counterclockwise as shown in FIG. When the gate of FIG. 1 is used for both start and stop purposes, it is not necessary to provide the intermediate gate with a timing device such as timer 72. FIG. 5 shows a simple gate that can be used as an intermediate gate.
The gate of FIG. 5 comprises the same tube 10 and the same rod 12 pivotally connected to the tube 10 at position 82 in a manner similar to that described in connection with FIG. However,
The brass sleeve 40 has been removed, and the brass sleeve 58 and its supporting structure are not needed. Furthermore, the stick 12
Need not be tilted to a staggered state, so the rod 20 can be removed. Thus, the lower end of the rod 12 can simply be connected to the tube 10 at 82 by a spring 86 or other resilient means. Stick 12
A lightly colored dish 74 is also provided at the lower end of the rod 12 to improve the visual display from the outside.
The configuration for piercing the lower end of the tube 10 of FIG. 5 is basically the same as that shown in FIG. 1, as indicated with the same reference numerals 76, 78, 80.

While the present invention has been described with particular reference to the accompanying drawings, it should be understood that other modifications than those shown or presented herein may be made within the spirit and scope of the invention.
