Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for separating para;/v, -1.

Conventional Paranco-1/Cut 117 flj l ~ 1 - 1 - Small diameter pipe with a piston held in advance by a spring to prevent it from operating due to the impact force when the Parancoat is opened. The structure is such that when the piston moves a predetermined distance by pushing the grease outward through the piston 11, the inertial body can move.

However, in such conventional parapet cutting equipment, the grease is affected by the environment in which it is used (especially temperature) and changes over time. The time varies considerably, and due to stiffness, the object (hereinafter referred to as "payload-1" is '1!'
If the JUJ separation occurs or does not separate, the payload and para-B at the time of payload landing on the water may be separated.
) There is a problem that reliable separation cannot be expected.

The present invention attempts to solve these problems by using a timer mechanism that does not use grease.
To provide a parachute separating device which can reliably separate a parachute from a payload without being affected by the usage environment or aging.

For this reason, the paranie 1 and separation device of the present invention is provided with a main body connected to the paranie 1 and the same main body,
The spring receiver is connected to the member, the payload nut is engaged with the member via the first movable engagement member, and the spring receiver described in F is biased in a direction to separate the payload nut from the main body. a spring interposed between the member and the payload nut;
an inertial body engaged via a movable engaging member; a trigger part tJ attached to the inertial body and provided with a return spring; The spring receiver is a timer mechanism that can start operating in response to a trigger action and move the second movable engagement member from an on position to an off position after a predetermined time to release the engagement state between the spring receiver and the inertial body. , and the timer mechanism normally supports the second movable retaining portion 'AA in the on position, but is capable of moving the second movable retaining portion 147J to the off position in accordance with a predetermined rotational displacement.'' The present invention is characterized in that it is provided with a timer for temporally regulating the rotational displacement of the cam portion opening.

Hereinafter, a parasitic system as an embodiment of the present invention will be explained with reference to the drawings.
-1. To explain the disconnection device, Fig. 1 is an explanatory diagram showing its action, Fig. 2 is a sectional view thereof, Fig. 3 is a schematic diagram to explain the action of the cam member, and Fig. 4 is an explanatory diagram showing its action. This is a front view showing a timer lock part (2) of the timer mechanism, and a cylindrical spring retainer 4 is provided in a main body 2 connected to a pallet 1 with a bearing 3 interposed therebetween.

This spring holder is connected and fixed to the payload 5 with a screw in the member 4, and a part of the payload nut 6 is inserted.Furthermore, the spring holder has a hole 7 on the circumference of the member 40 is formed in the hole 7, and a recess 6a of the payload nut 6 is formed in the hole 7.
A ball 8 serving as a first movable retaining member placed inside is engaged with this, and the spring receiver of the repay load naso 6 is engaged with the member 4 via the ball 8. 0
A spring 9 is interposed between the member 4 and the payload nut 6 in the spring receiver, and the spring 9 biases the payload nut 6 in a direction to separate it from the main body 2 side.

Further, in the main body 2, an annular inertial body 10 is fitted on the outside of the member 4 of the spring receiver, and this inertial body 10 is attached to a second
The spring holder is connected to the part 4 through the ball 11 as a movable retaining part.
A return spring 12 is interposed between the inertial body 10 and the main body 2, and this return spring 12
As a result, the inertial body 10 is biased toward the opposite side of the payload, that is, in the direction opposite to the direction in which the inertial force acts.

By the way, when Paran-1-1 is opened, the trigger (Tr
bottle 1 as a trigger part ladle that performs the action
3 is provided, and this bottle 13 is connected to the parang 1.3. - is connected to the tip of the center cord 17I.

The timer mechanism 15 starts operating in response to the trigger action of the bottle 13, moves the ball 11 from the on position to the off position after a predetermined period of time, and the spring receiver releases the engagement state between the member 4 and the inertial body 10. However, the spring holder in Part 4 is built into the space opposite to the partial space (+11).

This timer mechanism 15 is a cam that rotates counterclockwise in FIG. 3 and can move the ball 11 from an on position (a position shown by a solid line in FIG. 3) to an off position (a position shown by a chain line in FIG. 3). The cam member 16 is connected to a timer 17 having a spiral spring and a gear mechanism therein, and the timer 17 allows the cam part 1q'16 to time-regulate its rotational displacement. It is designed to receive.

However, a disc 18 as a timer lock member is attached to the timer 17, and the set hole 18 of this disc 18
Insert pin 3 into a.

Note that this disc 18 is also used for winding the spiral spring of the timer 17.

By inserting the pin 13 into the set hole 18a of the disc 18 in this way, the clocking action of the timer 17 is locked.
When it is pulled out from 8a, the timer lock state described in ``2'' is released and the mainspring spring is loosened, so that the timer 17 starts counting, and the cam member 16 starts to rotate accordingly. When the ball 11 rotates by a predetermined amount θ (this rotation takes a predetermined time), the ball 11 falls into the recess 16a of the cam member 16, and the ball 11 moves from the on position to the off position. 4 and the inertial body 10 are released.

In addition, a stopper] 9 is provided on the main body 2 side,
The grooved inertial body 10 has a claw 20 that can be engaged with the stopper 19.
is provided, and due to stiffness, the spring receiver is unable to release the engagement between the member 4 and the inertial body 10, and then the payload 50
When the inertial body 10 moves against the return spring 12 by a force of 1- due to a landing impact, the pawl 20 can engage the stopper 19.

With the above-mentioned configuration, the payload 5 having this device is transferred from the aircraft 21 to the release cable 22 as shown in FIG.
After that, the release cable 22 comes off the cover and the tipping cord 23 is released. ---
1.1 is pulled out 0 Then, the paranute 1.1 is fully opened and the tiploining cord 23 is cut, but the shock when this paranite 1 is opened causes the tip of the paranute center cord 14 to be tied to the tip. The pin 13 is pulled out from the set hole 18a of the disc 18.

When the pin 13 is pulled out from the seven-way hole +8a in this way, the timer mechanism 1 is triggered by the pin 13.
5 starts operating and its cam member 16 starts rotating, so after a predetermined time period when the cam member 16 has been rotationally displaced by a predetermined amount θ, the ball 11 falls onto the four parts 16a of the cam member ]6, and the ball 11 is turned on. The spring receiver moves from the position to the off position, whereby the retaining state between the member 4 and the inertial body 10 is released (1), and the inertial body (10) becomes free (0) After that, when the payload 5 lands on the water, due to the landing impact, Free inertial body 1
0 moves to the right in FIG. 2, and the claw 20 and the stopper 9 engage with each other.
Since the payload nut 6 becomes free, the payload nut 6 is reliably separated from the main body 2 by the biasing force of the spring 9.

Note that as the timer 17, in addition to using a spring spring type one, an electronic type that combines a quartz (crystal oscillator) and a gear mechanism can also be used.

As described in detail above, according to the paranito cutting and releasing device of the present invention, by skillfully combining the trigger member that performs a triggering action when the paranito is opened and the timer mechanism equipped with the cam member (9),
It is possible to make the time from the opening of the para-1 to the time when the spring receiver' member is released from the inertial body retaining state, and this force is enough to prevent the payload from separating early or becoming unable to separate. It has the advantage of preventing

Well, the present invention's paran--1.The disconnecting device is equipped with a timer mechanism that does not use grease.
It also has the advantage of being less susceptible to changes over time, and as a result, maintenance and inspection work can be performed extremely easily.
