Abstract

PURPOSE:To enable the easy execution of hovering training with ease by adopting the constitution in which pantographs, X-Y table and freely slidable imposing member are engaged in a perpendicular direction and that the load in the perpendicular direction is decreased in the state of mounting the plane body to be hovered. CONSTITUTION:The sliding blocks 55-58 are inserted to sliding shafts 59 and 60 horizontally mounted in parallel to the rear face of a base plate 71 of the X-Y table 7 and slide on the shafts 50, 60. The X-Y table 70 is, therefore, enabled to slide upward and downward in the perpendicular direction, i.e., the direction Z by the expansion and contraction of a pair of the pantographs 45, 46. A shaft 82 is implanted on the sliding blocks 80, 81 and the imposing member 83 to be imposed with the plane to be hovered is mounted freely rotatably and slidably with respect to the shaft 82. Further, tensile coil springs 94-97 are expanded near the fulcrum points 90-93 of the pantographs 45, 46 in such a manner as to extend the pantographs 45, 46 in the perpendicular direction by which the load in the perpendicular direction is decreased. The hovering training is thereby executed with ease.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a hovering training device for a radio-controlled helicopter.

(Prior art) In recent years, so-called aerial photography, in which images of the ground are photographed from the air using a flying object such as a helicopter, has been frequently carried out, but using a large actual aircraft for this aerial photography not only increases the cost. However, to prevent danger, it was not possible to shoot in any field. Therefore, by using remote radio-controlled, high-performance small helicopters equipped with still cameras, video cameras, etc., aerial photography is becoming more reliable and safe than with actual aircraft.

By the way, such a remote radio-controlled small helicopter
It requires skill to operate, and if you make a mistake, it will stall and crash.
There is a risk of damaging the expensive aircraft and onboard equipment. For this reason, an operator generally uses a radio-controlled small helicopter in a hovering training device IO with the configuration shown in Figure 3.
20 is mounted on the aircraft to conduct hovering training, which is the most difficult maneuvering technique. This hovering training device 10 consists of a pole 1 horizontally suspended on a support 11 so as to be swingable.
The structure is such that a small helicopter 20 is fixed to one end of the helicopter 2, and an MS 13 is attached to the other end to balance the two.

(Problem to be solved by the invention) Hovering like this! The structure of the II building equipment ftl0 not only restricts movement in the radial direction connecting the support 11 and the small helicopter 20, but also prevents flexible flight training. 11, it requires a relatively large space and has the problem of not being easy to train.

(Means for Solving the Problems) In order to solve such problems, the present invention provides an underframe having a horizontal IRM mechanism at its lower end and a pair of sliding shafts, and a frame having one end sliding on each of the sliding shafts. A pair of pantographs that are movably engaged and expand and contract in the vertical direction; an X-Y table that is slidably engaged with the other end of the pantograph in the horizontal direction; and a pair of pantographs that are movably engaged on the table. The mounting member is provided with a mounting member.

(Function) It can be moved freely in all directions including the Z direction by expanding and contracting the pantograph, the X and Y directions by the x-y table, and the θ direction by the swingable 8-position member, and the horizontal m node at the lower end. By adjusting m by, the sliding resistance of the entire device can be reduced.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a front view of the hovering training device according to the present invention, and FIG. 2 is a right side view of FIG.
Reference numerals 31 and 32 denote a pair of sliding shafts, the ends of which are fixed in parallel to support frames 33 and 34 with an appropriate gap therebetween, thereby forming an underframe 35. Support frame 3 of underframe 35
At each side edge of 3 and 34! lif! i screw 3
6.37.38 and 39 are screwed into the horizontal position f! to keep the underframe 35 horizontal. It constitutes the i mechanism 40.

A pair of sliding blocks 41 and 42 and a pair of sliding blocks 43 are respectively attached to the sliding shafts 31-32 of the underframe 35 configured in this way.
and 44 are inserted and slide on the sliding shafts 31 and 32. Lower open ends 47 and 48 and 49 and 50 of a pair of pantographs 45 and 46 are rotatably pivoted to these sliding blocks 41-44. Lower open ends 51 and 52 and 53 of pantographs 45 and 46
and 54 are also rotatably pivoted to sliding blocks 55 and 56 and 57 and 58, and these sliding blocks 55 to 58 are horizontally parallel to the lower surface of the base plate 71 of the X-Y table 70. It is inserted into the suspended sliding shafts 59 and 60 and slides on these shafts 59 and 60. Therefore,
By expanding and contracting a pair of pantographs 45 and 46,
The table 70 can move up and down in the vertical direction, that is, the Z direction.

The X-Y table 70 has the same structure for both the X-axis and the Y-axis, and has sliding blocks 74 and 75 inserted into sliding shafts 72 and 73, which are horizontally suspended in parallel on a base plate 71, and sliding blocks 74 and 75, respectively. Sliding shafts 77 and 78, which are horizontally supported at right angles to the sliding shafts 72 and 73 and parallel to each other, are inserted onto a base plate 76 that is horizontally supported on the moving blocks 74 and 75, and are connected to each other. It consists of sliding blocks 80 and 81.

A shaft 82 is installed on the sliding blocks 80 and 81 of this X-Y table 70, and the hovering aircraft is
A pillow ball 84 embedded in a mounting member 83 formed into a shape suitable for mounting is press-fitted into the tip of the shaft 82,
A mounting member 83 is attached to the shaft 82 so as to be rotatable and movable.

The outline of the hovering training device according to the present invention has been explained above, but due to its purpose of use, the hovering training device needs to be able to move freely in all directions with near zero resistance while carrying the hovering object. , For this reason, bearings (not shown) are used for each rotating or sliding part to reduce resistance, and the fulcrum 90.91 of the pantograph 45.48 is
．． Near 92 and 93, tension coil springs 9495.4B are installed to extend the pantograph 45.4B in the vertical direction.
9B and 97 are stretched to reduce the vertical load. In addition, in order to reduce the vertical load, use tension coil springs 94, 95, 96 and 97 as shown in the figure.
In addition to providing support frames 33 and 34 and t8vI block 4
1.42. A compression coil spring may be inserted between 43 and 44.

(Effects of the Invention) The present invention reduces the vertical load to zero by vertically engaging a pantograph, an X-Y table, and a slidable U-mounting member, and in a crutch configuration carrying a hovering aircraft. Because of this configuration, the hovering target aircraft moves in all directions with almost no resistance, and hovering training similar to that performed in the air can be performed.

In addition, since a pantograph was used for vertical displacement,
The J device can be made smaller, training can be performed even in narrow spaces, and it is easy to transport.
