DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a two-part connector for harness straps for use in aircraft canopies, parajuice navies, etc., and more particularly to a two-part connector for automatically releasing such harnesses. This invention relates to a harness release device.

The above-mentioned harness refers to a belt used to hold a passenger in an aircraft seat, a belt used by parachutes, or a belt used to hang luggage from a parachute.

There are many types of harness release devices currently in use.

One such harness release device is disclosed by John, A., dated May 18, 1965, assigned to the same assignee as the present application.
No. 3,183,568 to Gaylord.

The harness release device includes female and female strap connectors each having a rear end adapted to engage one and opposite ends of the harness strap.

The female strap connector has a forwardly projecting connector prong adapted to be engaged in a prong receiving groove in the female strap connector.

A transverse shaft or detent having a cutout or detent located in alignment with the tongue receiving groove is rotatably mounted within the female strap connector intersecting the tongue receiving groove. It is suspended.

The two ends of the harness are coupled together by a female strap connector tab inserted into the tab receiving groove and secured by the transverse shaft.

Devices have also been previously devised for power-release of such harness connectors in case of emergency.

One such device was purchased by Mr. John A. Gaylord on November 30, 1971, assigned to the same assignee as the present application.
No. 3,624,674.

Although these types of canopy release devices have proven reliable, there is a need for improvements in these harness release devices, particularly automatic harness release devices.

Accordingly, it is an object of the present invention to provide an improved harness release device.

Another object of the invention is to provide a power operated harness release device.

Another object of the present invention is to provide a power operated harness release device that can be opened automatically in an emergency situation when the harness is in a fluid medium such as water.

According to an exemplary embodiment of the invention, /'l-ness and
A two-part separable connector is provided, such as a female strap connector and a female strap connector having an interface with the strap, the protruding tab of the female strap connector being connected to the female strap connector. When inserted into the receiving groove of the connector, these tabs are secured within the receiving groove by a fixing or transverse shaft mounted within the frame of the female strap connector.

An internal release pin is used to automatically release the fixation.
By moving the release pin in an arc, the transverse or locking shaft is securely coupled to the transverse or locking shaft in the female strap connector for corresponding rotation.

This internal release pin is forced to move, ie moved in an arc, so as to rotate the transverse axis into the unlocked position.

An electro-optic actuator that senses the presence of a fluid medium, such as water, moves this internal release pin to separate the two-part strap.
It acts to trigger a force device that automatically releases or disconnects the connector.

The electro-optic actuator includes a sensing device that detects the presence of a fluid medium and an explosive device actuated by the sensing device.

This sensing device includes a light source such as a light emitting diode (LED) at one end of the light path, a photodetector that detects the light from the light source at the other end of the light path, and a combination of the light source and the photodetector. An intermediate prism device that transmits light from the light source to the photodetector only when immersed in the fluid medium and an electronic device capable of responding to signals from the photodetector can be included.

The explosive device includes a piston device mounted at a position where it engages with an internal release pin so as to be able to drive the release pin, and an explosive that is detonated by an electrical signal from an electronic circuit device.

In operation of the device of the invention, once the prism arrangement of the sensing device is immersed in water, light is transmitted along a controlled path consisting of a light source to a photodetector.

The output of the photodetector acts to activate an electronic trigger circuit, detonating the explosive charge within the detonator and causing the piston device to actuate the internal release pin.

The force applied to the release pin acts on the release pin to rotate the transverse or locking axis within the female strap connector, thereby causing the female and female strap connectors to rotate.
The connector can be separated and the harness can be released.

Other objects and features of the invention will become apparent to those skilled in the art upon reference to the following description and accompanying drawings.

This will be explained below with reference to FIGS. 1 to 8.

The harness release device according to the present invention has a female strap
2, including a connector 2 and a female strap connector 4;
consists of parts.

The female strap connector 2 has a frame body 6, and a shaft 10 is fixed in holes 8 on both sides of the frame body 6 to form a harness strap connection part.
One end of the strap is engaged by a loop on the harness strap.

At the front of the shaft 10 are protruding connector protrusions 12 and 1.
z, each having a detent recess 14 and 14'.

The female strap connector 4 has a frame 16 with a shaft 20 fixed in holes 18 on either side thereof to form a harness strap connection, the shaft 20 being connected to opposite ends of the harness strap. , is engaged by a loop of the same harness strap (not shown).

A pair of protrusion receiving grooves 22 and 2z are formed in the frame body 16. These receiving grooves are formed in the female strap connector 2.
The harnesses are connected to each other by receiving the projecting pieces 12 and 12', respectively.

The horizontal shaft 24 is pivotally supported by the frame 16 behind the projection receiving grooves 22 and 22'.
' assumes a rotational position in which the female strap connector 2 is secured by engagement with the projections 12 and 1z, respectively.

A notch (not shown) is formed on the horizontal axis 24 and is aligned with the sleep protrusion receiving grooves 22 and 2z.

When the harness is connected, the female strap
Projecting piece 12 of connector 2 and recesses 14 and 14 of 1z
' engages with the transverse shaft 24 of the female strap connector 4 to prevent the protrusions 12 and 1z from being pulled out of the protrusion receiving grooves 22 and 2z, respectively, thereby securing the harness release device.

When the horizontal shaft 24 is rotated counterclockwise as viewed from the viewing direction of FIG. and 1
4' 1, the protrusions 12 and 12' of the female strap connector 2 can be pulled out from the protrusion receiving grooves 22 and 2z, respectively, thereby converting the female strap connector 2 into a female strap connector. Separated from 4,
Release the harness.

The horizontal shaft 24 is a yoke lever, that is, a release lever 26
You can also rotate it manually.

The yoke lever 26 has lever arms 28 at both ends,
The inwardly facing teeth 30 fit into grooves 32 in the transverse shaft 24 that are separated by ribs 34 at both ends of the transverse shaft 24 .

Yoke lever 26 and transverse shaft 24 have a common central axis and each is capable of rotational movement about this common central axis.

When the yoke lever 26 is rotated counterclockwise, the tooth 3
0 contacts the rib 34 and rotates the horizontal shaft 24 counterclockwise, causing the horizontal shaft 24 to leave the recesses 14 and 14', and the protrusions 12 and 12' to be inserted into the protrusion receiving grooves 22 and 22, respectively. ’.

The transverse shaft 24 and yoke lever 26 are pivoted on support pins 36 on opposite sides of the frame 16.

The coil spring 38 supported by the support pin 36 and the frame 16 tends to rotate the horizontal shaft 24 clockwise.

The fixing flap 40 that fixes the yoke lever 26 is
It is mounted on the frame 16 by support pins 42 and 44 protruding from holes on both sides of the frame 16.

Coil springs 46, 48 supported by support pins 42, 44 and frame 16 act to rotate locking flap 40 counterclockwise to lock yoke lever 26 in a locked position.

The overlapping of the securing flap 40 over the yoke lever 26 is clearly shown in FIG.

To couple female strap connector 2 to female strap connector 4, tabs 12 and 12' are inserted into tab receiving grooves 22 and 22', respectively.

The forward ends of the tabs 12 and 12' push the tab 1 by pushing against the biased or spring-loaded transverse shaft 24.
2 and 12', respectively, protrusion receiving grooves 22 and 22'
The transverse shaft 24 is rotated counterclockwise against its direction of rotational bias until the notched portion of the transverse shaft 24 is rotationally displaced to permit complete insertion therein.

The arrangement including teeth 30, ribs 34 and springs 38 allows rotation of transverse shaft 24 without moving yoke lever 26.

When the front ends of the recesses 14 and 14' pass the transverse shaft 24, the spring 38 snaps the transverse shaft 24 into the fixed position.

To manually release the female strap connector 2 from the female strap connector 4 after it has been coupled, the locking flap 40 is pivoted and the yoke lever 26 is opened.

Then, the yoke lever 26 is rotated counterclockwise.

When the yoke lever 26 rotates counterclockwise, the teeth 30 of the yoke lever 26 engage the ribs 34 on the transverse shaft 24, causing the transverse shaft 24 to rotate counterclockwise, thereby causing the transverse shaft 24, and thus its By rotationally displacing the upper notch portion, the protrusions 12 and 12' can be pulled out from the protrusion receiving grooves 22 and 2z, respectively.

The coil springs associated with the yoke lever 26 and the locking flap 40 return the members to their original positions after the forces on the yoke lever 26 and the locking flap 40 are released.

Further details of the construction and operation of the harness release device described above may be found in U.S. Pat.
No. 83568, the disclosure of which is expressly incorporated herein by reference.

To provide an automatic, power-operated release device, the harness release device utilizes an electro-optic actuator 50, shown in FIG. 2, mounted within the female strap connector 4.

The electro-optic actuator 50 has an envelope 52 that includes a sensing device (FIG. 6), generally designated by the reference numeral 54, and an explosive device (FIG. 4), generally designated by the reference numeral 56. ), and both sensing device 54 and explosive device 56 are embedded in potting compound 57 to provide environmental and mechanical support for those parts.

The sensing device 54 in FIG. 6 is a light emitting diode (LED).
The light source 58 includes a light source 58 located at one end of the light path, and a photodetector 60 for detecting incident light from the light source 58 is disposed at the other end of the light path.

In the middle of the light path between the light source 58 and the photodetector 60 is a prism arrangement 62 surrounded by side walls 64, 66 and 68, which in this example has the configuration of a hollow triangular prism.

Reflector 70 is mounted on threaded enclosure 72 and mounted on tag side wall 64 .

This threaded connection ζ allows adjustment of the position of the reflector 70 relative to the side wall 64 to provide optimal reflection of the light beam to the photodetector 60.

Thus, a precisely defined light path can be created to protect against fluctuating light rays that might activate the photodetector 60.

In a preferred embodiment, the element 58 serving as a radiation source generally comprises a light emitting diode (LED) as a light source.
) rj, etc., and emits light in the infrared portion of the spectra.

The photodetector 60 is, for example, a photodetector tuned to a specific wavelength, specifically to detect infrared radiation.

Light from a light source 58 is emitted from an LED and follows a precisely defined light path and is reflected by a reflector 70 such that only the light of a particular wavelength is incident on the most sensitive portion of the photodetector 60. so that the light is filtered by at least one of filters 80 and 90.

Although two filters 80 and 90 are shown, it will be appreciated that in many cases only one filter is sufficient.

Light source 58 is mounted to frame 76 behind an aperture 78 in side wall 68 .

A plate or filter 80 made of a material that transmits the light rays emitted from the light source 58 is mounted in the aperture 78 .

O-ring 82 seals aperture 78.

Similarly, photodetector 60 is mounted within frame 84 behind an aperture 86 in sidewall 66 .

A plate 88 made of a material that transmits the light rays emitted from the light source 58 is mounted in the aperture 86 .

A filter 90 located behind plate 88 in the preferred embodiment attenuates all light waves other than the specific wavelengths that reach photodetector 60 .

The opening 86 is sealed by an O-ring 82.

Sensing device 54 also includes electronics that are activated by the output signal from photodetector 60 coupled thereto.

The electronic components of the electronic device are mounted on an electronic circuit board 74 secured within the enclosure 52.

FIG. 9 is a schematic diagram of the electronic circuitry of the electronic device, which will be explained in further detail below.

As shown in FIG. 7, when the hollow prism device 62 is placed in an air environment, the prism function does not occur, and the path of light from the light beam S is the fourth path R, P. ,1
, and passes through a hollow prism device 62 and a reflector 70 .

When the hollow prism device 62 is filled with water,
The light path is the second path R, P as shown in FIG.

Pass through 2.

Light rays incident from the light source S pass through the plate 80 into the water environment, are reflected by the reflector 70, enter the plate 88, and pass through it.

In operation, when electro-optic actuator 50 is in an air environment (see FIG. 1), light from light source 58 is directed toward reflector 7.
0 and does not reach the photodetector 60.

When the electro-optical actuator 50 is immersed in water (see FIG. 8), the water fills the hollow prism device 62 and light is reflected by the reflector 70 to the photodetector 60).

The photodetector 60 detects the wavelength of light emitted by the light source 58 and produces an output signal that is processed within the electronics and utilized to effect automatic release of the two-part harness in a manner described below. be done.

Essentially, electro-optic actuator 50 acts as a light switch that is open when in an air environment and closed when prism device 62 is filled with water.

Explosive device 56 includes two concentric cases 92 and 94, first and second, rigidly mounted within envelope 52.

In the first or lower case 92. An explosive charge 96 is loaded, and the explosive charge 96 is detonated by an electrical signal from the circuit of the electronic device shown in FIG.

Membrane 98 prevents explosives from escaping from the top of first case 92 prior to detonation.

A piston 100 is slidably mounted in the second or upper case 94.
02 and a downwardly outwardly projecting collar 104 which engages a shoulder 106 of the second case 94 in the piston-up position (FIG. 5) to move the piston into the second position after detonation. It is held in a case 94.

The release hinge 108 shown in FIG. 4 is fixed to the horizontal shaft 24,
It extends upwardly through an aperture in the frame 16 near the lever arm 28.

The release pin 108 has a head 110.
is in a position to engage with the upper end surface of the piston 100.

The explosion of the explosive charge 96 causes the expansion of the gas and the piston 100
Press upward to contact the tapered neck of the release pin head 110.

The rise of piston 100 causes release pin head 110 .
Therefore, the release pin 108 is driven in an arcuate manner, thereby
This results in a corresponding movement of the transverse axis 24 (FIG. 5).

However, at this time, the yoke lever 26 does not move.

Movement of piston 100 and release pin head 110 due to movement of piston 100
Rotation of the transverse shaft 24 due to movement of the release pin 108 aligns the notched portion of the transverse shaft 24 with the grooves 22 and 22'.
Release the tabs 12 and 12' of the female strap connector 2, respectively.

FIG. 5a shows a portion of the explosive device 56 shown in FIG. The state is shown fixed inside the outer enclosure 52 via a plug device 53 which is detachably attached to the outer enclosure 52.

According to the configuration shown in FIG. 5a, after the explosive charge 96 has been detonated, the first case 92 is removed from the enclosure 52 and the plug device 53 is then removed, thereby removing the detonated explosive charge and removing it. Instead, it becomes possible to reload new explosives 96.

Power for the electro-optic actuator 50 is provided by a battery 1121 held in a battery housing 114 which is slidable into the electro-optic actuator 50 by screws or other suitable means. is maintained.

As a further safety feature, electronic circuit board 74, light source 58 and photodetector 60 are provided to prevent accidental release of the harness.
Power is supplied to the readiness sensor (ar?) connected to the power supply.
mingsensor ) 116 and a readiness sensor 118 connected to electronics circuitry, a light source 58 and a photodetector 60 .

Submerging electro-optic actuator 50 in water creates a conductive path between these readiness sensors 116 and 118, completing an electrical circuit.

Referring now to FIG. 9, a schematic diagram of an electronic trigger circuit specifically configured as an electronic device generates an electrical control signal for detonating explosive charge 96 in response to the incidence of light on photodetector 60. An electrical diagram is shown.

In FIG. 9, the light source 58 is represented by a light emitting diode, indicated by t'l, LED, the photodetector 60 is represented by a phototransistor, indicated by PD, and the detonator for the explosive is Electric detonator (EE) with reference number 95
D).

As shown in FIG. 9, the LED of the light source 58 and the resistor R
1 is connected in series between the readiness sensor 118 and ground.

A positive voltage is applied to the circuit through the readiness sensor 116 and the fluid coupled between the readiness sensors 116 and 118.

As is well known, the phototransistor PD, which is the photodetector 60, has an electrical property that its electrical resistance changes depending on the incidence of light.

One terminal of the phototransistor PD is connected to the positive terminal of the power supply terminal, and the other terminal is connected to ground via a resistor R2.

Resistor R2 and phototransistor PD form a voltage dividing circuit.

The connection point between the phototransistor PD and the resistor R2 is the first
is connected to the anode A of the programmable unijunction transistor PUT1 and to the junction of resistor R13 and capacitor C1.

The gate G of the transistor PUT is connected to the voltage dividing resistor R5.
and connected to the connection point of R14 to the transistor PUT
The cathode of No. 1 is connected to ground via a resistor R3.

The cathode of the transistor PUT1 is also connected to a first timing circuit consisting of a variable resistor R6 and a capacitor C2.

This circuit controls the operation of a switching element such as the silicon controlled rectifier 5CR1, and is connected to the connection point between the GG-J variable resistor R6 of 5CR1 and the capacitor C2.

Variable resistor R7 and capacitor C3 form a second timing circuit, which is connected between the cathode output of silicon-controlled rectifier 5CR1 and ground.

Anode A of the second programmable unijunction transistor PUT2 is connected to the junction of variable resistor R7 and capacitor C3.

This second unijunction transistor PUT
The gate G of 2 is connected to the connection point between the resistor R0 and the anonide of the diode D1.

The other end of resistor R0 is connected to cathode K of silicon controlled rectifier 5CR1.

The cathode of this silicon controlled rectifier 5CR1 is also connected to a third timing circuit consisting of a variable resistor R11 and a capacitor C6.

A resistor RIO is connected between the cathode of diode D1 and ground.

The cathode of the transistor PUT2 is connected to ground via a resistor R8, and at the same time is connected to the anode of a diode D2.

The cathode of diode D2 is connected to the gate circuit of a second selectively energizable switching element, such as 5CR2.

The anode A of 5CR2 is the variable resistor R11 and the capacitor.

connected to the connection point.

5CR2 cathode It. It is connected to an electric detonator (EED) 95 that completely heats up and detonates when electric power is applied.

A resistor R12 is connected in parallel with the electric detonator 95. A capacitor C4 is connected between the gate (G) of 5CR2 and ground.

For operation of the trigger circuit shown in FIG. 9, when the trigger circuit is immersed in water, power is supplied to the circuit through the high power readiness sensors 116, 118, and light is supplied to the circuit through the LED of the light source 58. It is transmitted through the more water-filled prism device 62 to the phototransistor PD.

The light reduces the electrical resistance of phototransistor PD, photodetector 60, increases the current flowing through it, and increases the voltage at anode A of transistor PUT1.

When the voltage at the anode A of transistor PUT1 reaches a predetermined limit level, transistor PUT,
is switched on, its cathode causes current to flow through resistor R3, and the voltage across resistor R3 rises.

This increased voltage is applied to the gate G of the silicon controlled rectifier 5CR1 via the connection point between the variable resistor R6 and the capacitor C2 of the first timing circuit.

Variable resistor and capacitor C of the first timing circuit
After expiration of a first set time determined by 2, the silicon-controlled rectifier 5CR1 is switched into conduction, thereby energizing the two subsequent time-controlled trigger circuits.

The current is then transferred by the cathode of the silicon controlled rectifier 5CR1 to the two timing circuits, namely the variable resistor R
7 and a capacitor C3, and a third timing circuit including a variable resistor R11 and a capacitor C5.

Essentially, the third timing circuit functions to charge a capacitor C5 that stores a charge for igniting an electrical detonator (EED) 95.

After a set time determined by the variable resistor R7 and the capacitor C3 of the second timing circuit, the voltage at the anode A of the transistor PUT2 reaches the limit voltage;
The transistor PUT2 is switched to the on state, and its cathode causes current to flow through the diode D2 to the gate G of 5CR2, making 5CR2 conductive and causing current to flow through the electric detonator (EED) 95, causing it to heat up. Explosive charge 96 is detonated, pushing piston 100 upwardly and uncoupling female strap connector 2 and female strap connector 4.

Variable resistors R6, R7 and RttE are shown as variable so that the set time can be adjusted.

Although the prism device 62 in the above embodiment is shown as a hollow prism, when it is filled with air, it essentially does not have a prism function for the light rays incident from the light source.

Therefore, the first paths R, P, 1 shown in FIG. 7 are created for the incident light beam.

When the prism device 62 is filled with water, the prism function for the light rays incident from the light source is reflected, and the second paths R, P, 2 shown in FIG. 8 are created for the incident light rays. .

As the liquid environment in which the prism device 62 of the electro-optic actuator 50 is placed, in the above embodiment, a water environment was described as a typical example, but in an environment of liquids other than water, the liquid may When the inside of the hollow prism device 62 is filled as shown in FIG.
If the liquid has a refractive index that causes total reflection, the same effect as in the above embodiment will be achieved.

As a modification of the prism device 62 described above, a solid prism can also be used.

In that case, the prismatic function of a solid prism for a light ray is manifested by the reflection of the light ray when the solid prism is in an air environment.

On the other hand, when the solid prism is in a liquid environment, such as water, the prismatic function of the bezel is diminished.

Thus, the prism device will create two paths for the incident light ray, depending on the environmental conditions in which it is placed.

Therefore, when using a solid prism as the prism device 62, the light detector 60 enters the prism device 62 from the light source 58 on the opposite side of the prism device 62 from the light source 58, unlike the position shown in FIG. It is placed at a position where the light beam passing through the reflective surface 62 is incident.

Moreover, even in a liquid environment other than water, the solid prism 62
If the liquid has a refractive index such that the light beam incident on the liquid passes through the reflecting surface and is transmitted into the liquid, the same effect as described above will be performed.

It should be noted that while the above trigger circuit of the present invention has been illustrated and described for use with a three-part harness combined with one automatic harness/release device, it may also be used with a life jacket for controlling an inflator. It can also be applied to applications related to life rafts and the like, and has many other applications, such as, for example, applications in automatic control of liquid levels.
