[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION The present invention relates to towing capable of separating and dropping a towing sleeve body used as a target for advertisement display on a third party or equipment facilities on the ground, at sea, or in the air, or as a target for shooting training with a military aircraft. Related to body devices.

[0002]

2. Description of the Related Art Various methods have been put into practical use as a method of towing a towing body or a sleeve body for advertisement or targeting, and among them, a typical one is a typical one. There are the following two methods.

A. A sleeve body is attached to the towing aircraft via a towing line in advance, and the towing line and the sleeve body are placed on the runway of the airfield so that they do not slack, take off as it is, take off, return to the airfield, and then return to the towing line. How to disconnect.

B. Take off with the tow line of the tow body wound around the reel device of the aircraft, and when it arrives at the destination, pull out the tow line from the reel device, tow the tow body, use it as a target, and wind up the tow line on the reel device How to return the towed body to the aircraft.

The above method A is particularly suitable when the sleeve body is used for advertising and promotion, and can also be used for targeting, but has the following problems.

(1) It is necessary to manually deploy a tow line and a tow body on a runway before flight.

(2) Since the takeoff must be performed with the tow line and the tow body being deployed on the runway, the tow line and the sleeve body rub against the runway surface during takeoff and wear occurs. The rope may be vibrated, rotated, twisted, or the like, and there is a problem in safety during takeoff of the aircraft.

(3) Since it is necessary to perform towing flight from the takeoff point to the point required to display the sleeve with the tow rope and sleeve body causing air resistance deployed, the resistance is large and inefficient.

(4) The tow line is 600 to 8 for target
00m long and 100-15 for advertising
Because it has a length of about 0 m, if the tow line is cut off with the sleeve attached to the end of the tow line, it is difficult to collect and clear it (the long tow line scattered on the ground must be wound up) In addition, there is a possibility that the detached sleeve body is flown in the air and falls outside the airfield.

On the other hand, the above method B is widely used for targets because it does not have the above-mentioned problem at takeoff, but has the following problems.

(1) When a relatively large towing body for a target is drawn to the vicinity of an aircraft by pulling in the towing line, there is a risk that the turbulence generated near the aircraft may deteriorate the flight stability of the towing body and the towing line. is there.

(2) When the towing body attached to the towing line extended in the air lands, the towing body is rotated or shaken, and the drawn towing body may collide with the aircraft.

[0013] In addition to the above method, the aerial towing sleeve is folded in a streamlined tube, the tail end of the tube is cleaved, and the air inside the tube is opened by the local vacuum generated there. A method for releasing the towing sleeve was proposed (Japanese Patent Publication No. 7-2)
No. 006), this method does not allow timely and smooth opening of the sleeve body. Therefore, this method has never been adopted.

Accordingly, it is an object of the present invention to provide an apparatus which can take off in a stowed state and easily disconnect an aerial towing sleeve opened at a desired point.

[0015]

Means for Solving the Problems In view of the above problems, as a result of diligent research, the present inventor has attached a foldable arm to a sliding cylinder provided on a towing body, which is movable back and forth, and a sleeve of a sleeve body is attached to the tip of the arm. It has been discovered that if the armature is detachably engaged, the arm can be rotated backward by the retraction of the sliding cylinder, and the sleeve body can be easily and reliably separated, and the present invention has been conceived.

That is, the aerial towing sleeve body 3 of the present invention.
(A) a sliding cylinder 13 protruding rearward of the towing body 1 and movable back and forth; and (b) a plurality of arms pivotally attached to a rear end of the sliding cylinder 13. 12, an arm 12 in which each of a plurality of crown-shaped fittings 19 attached to the open end of the sleeve body 3 is detachably mounted on a distal end portion; and (c) the arm 12 in a tow state of the sleeve body 3. (D) a drive mechanism for moving the sliding cylinder 13 back and forth, and the sleeve 14 is attached to the distal end of the expanded arm 12 while the sleeve 3 is towed. Coronal bracket 19
When the sliding mechanism 13 is pulled into the towing body 1 by the drive mechanism, the arm 12 rotates backward, and the crown fitting 19 is detached from the arm 12. Thereby, the sleeve body 3 is separated from the towing body 1.
