RELEASABLE PARACHUTE HARNESS Filed June 19, 1956 5 Sheets-Sheet 3 INVENTOR.

Edward A.6imalouski (a P BY United States Patent 1 2,986,362 RELEASABLE PARACHUTE HARNESS Edward A. Gimalouski, Manchester, Conn., assignor, by

mesne assignments, to Pioneer Parachute Company,

Inc., Manchester, Conn., a corporation of Delaware Filed June 19, 1956, Ser. No. 592,343 4 Claims. (Cl. 244-151) This invention relates to parachute harnesses capable of being readily released from a wearer and is directed particularly to actuating means for releasing connectors employed in such harnesses.

The parachute harness shown and described in my issued Patent No. 2,726,832 is typical of a type of harness which is releasable from a wearer so that the wearer may free himself from the harness promptly after landing and even though heavily laden with cumbersome equipment. Harnesses of this type are particularly useful for paratroopers, fire fighters and others who may have occasion to make a parachute jump while carrying arms, floats, fire extinguishers, shovels or other bulky equipment. However, because the harness can fall away from the wearer when released, it is essential that the actuating means used to effect such release shall be foolproof and incapable of accidental operation. At the same time, it must be capable of ready operation even when the user is wearing thick or heavy gloves or mittens.

In accordance wtih the present invention, a parachute harness having releasable elements is provided with actuating means which are readily operable when required, but are normally locked against movement so as to prevent accidental operation thereof. The construction preferably is such that at least two and preferably three, successive movements or operations are required in actuating the device. However, each movement is capable of being performed readily with gloved hands and by either the right or left hand as may be necessary in an emergency.

For this purpose the present invention provides harness releasing means with an actuating device having an operating handle formed with telescoping elements. The handle elements are held in collapsed and locked relation during normal usage of the harness so that the handle will not project outward to a position in which it might be accidentally actuated or catch upon clothing or articles carried by the wearer. However, when the parachutist is approaching the ground the handle may be easily manipulated to cause the elements to expand so that the handle will be prominently positioned and easily movable to release the harness from the wearer. More over, if the handle should be struck or otherwise acci dentally caused to expand to an unlocked condition, the wearer will immediately be aware of this fact by reason of the projection of the handle and can restore it to its locked condition again. The construction also may be provided with a loading position for the handle in which the handle may be retained while leaving both hands free to fasten and adjust the harness and fittings. Similarly, the handle may be locked in open position preventing accidental return of the elements to locked relation.

One of the objects of the present invention is to pro vide a parachute harness with novel means for effecting release thereof from a wearer.

Another object of the invention is to provide a parachute harness with releasable means requiring successive movements to actuate the same.

A specific object of the invention is to provide actuating means for releasing a parachute harness and including a handle embodying telescoping elements movable from a collapsed and locked position to an expanded operating position.

These and other objects and features of the present invention will appear from the following description thereof in which reference is made to the figures of the accompanying drawing.

In the drawing:

Fig. 1 is a perspective illustrating a typical form of parachute harness and actuating means embodying the present invention;

Fig. 2 is a plan view of the actuating device of Fig. I mounted on a removable chest piece of the harness with parts thereof broken away;

Fig. 3 is a vertical sectional view taken on the line 3-3 of Fig. 2; and

Fig. 4 is a sectional view taken on the line 4-4 of Fig. 2.

In that form of the invention chosen for purposes of illustration in the drawings the harness is of the type shown and described in Patent No. 2,726,832. The harness embodies a sling having a seat portion 2 terminating in attaching links 4 located near the wearers hips. Leg straps 6 are secured to the seat portion and arranged to extend forward and upward between a wearers legs, terminating in loops 8 which loosely engage the seat portion near the ends thereof. The links 4 are releasably engageable with

connectors

10 and 12 secured to the lower ends of

side riser portions

14 and 16, respectively, of a chest piece 18 of the harness.

The upper ends of the

side riser portions

14 and 16 of the chest piece are provided with

connectors

20 and 22, respectively, adapted to be releasably engaged by. links 24 carried by shoulder portions 26 of the harness. The shoulder portions are arranged to pass rearwardly over a wearers shoulders for attachment to a parachute contained in a back pack or seat pack (not shown) which may be secured to the harness. The harness also may have other straps such as the body engaging straps 28 as desired for securing the harness in place on a wearer.

The harness may, of course, be of any other suitable type embodying quick release elements operable simultaneously to permit the wearer to disengage various straps of a harness in removing the same. However, in the preferred form of the invention the harness includes a removable chest piece having separable side riser portions releasably connectable with the seat portion and shoulder portions of the harness. The attachment of the free ends of the leg straps to the seat strap may be effected by means of the loops 8 as shown, or in any other suitable way as, for example, by connectors as illustrated in my issued Patent No. 2,726,832. The

side riser portions

14 and 16 of the harness preferably are provided with attaching rings 30 to which a chest pack 32 may be secured. The harness also may have other rings or means (not shown) for attachment of other types of equipment thereto as desired.

The

connectors

10, 12, 20 and 22 by which the chest piece 18 and

side riser portions

14 and 16 are connected to the seat portion and shoulder portions of the harness may be of any suitable or preferred type and may be actuated by cables or the like upon operation of the actuating device 34. As shown, the connectors are of the type illustrated and described in copending application Serial No. 479,566, filed January 3, 1955. Such connectors are formed with a body 36 having a pair of latching elements 38 therein engageable by one or another of the

links

4 and 24 to hold them in connected relation. However, the latching elements are movable to link releasing position by means of a slide 40 operable by a cable 42. The latching elements and slide are normally urged toward their link retaining positions by

springs

44 and 46, respectively, but are movable against the action of said springs by the cable 42 and pivoted arms 43 upon operation of the actuating device 34. The latching elements Patented May St), 196 1 have pins 45 thereon which project into openings 47 in the slide 40 and are held in the restricted part 49 of the recess when the harness is secured on the wearer whereby the, latching elements are held against outward, movement to release the link therefrom.

'Ihe actuating device employed for. Qulli gon cables, 42- preferably is enclosed within a housing. 48. mounted. near. the center of a rather stiff base 50 on thechest, piece 18. A. drum 52 is secured to a stud 5.4 rotatably mounted within the housing 48 and has thev ends of each. of the cables 42 attached thereto. Four cables may be provided so that one. cable may extend to each Oi t e.

connectors

10, 12, 20 and 22 on the ends of the side riser portions, of the chest piece for simultaneous operation ofthe' con: nectors upon rotation of the drum 52.v When rotated the cables 42 are wound upon the drum pulling the ca les and moving the slide 40 and latching elements 38 of the connectors to release the links on the seat portion; and shoulder portions of the harness. The

slide riser portions

14 and 16 of the chest piece 18 are thereby disengaged from the harness whereby the; chest piece may'fall away and the harness as a whole may bedisearded by the wearer without difliculty.

In order to rotate drum 52, the actuating device 34 is provided with a handle 56 which is formed at its lower end with a slot which receivesthe flattened or squaredend, 58. of the rotatable stud 54 projecting to the exterior of the housing 48. The handle is thus movable-in an arc to rotate the stud 54 and drum S2 to pull on the cables 42 and actuate the connectors 10,112 20 and 22 The handle 56 is arranged to extend through a slot 60 formed in an outwardly projecting flange 62 whichmay be formed integral with the marginal base 64 oi the housing 48. The slot 60 is provided with enlarged opem.

ings

66 and 68 at the ends thereof, whereas the intermediate portion of the slot is formed with two

ofiset portions

70 and 72 connected by a transverse channel 74. By reason of this formation of the slot,60, movement of the handle from the enlarged end 66 of the. slot toward the. opposite end 68 requires three successive movementsnamely, movement in an arcuate direction through portion 79, lateral movement through the transverse channel 74 and further arcuate movement through the ofiset portion 72 of the slot. The lateral movement of the handle is permitted by reason of the spring member 71 which engages the slotted end of the handle and is held in place by a retaining plate 73 secured to the reduced end 58 of stud 54.

- The handle 56 is formed of two telescoping elements which are relatively movable radially of the stud 54 so as to assume either a collapsed locking position or an extended operating position. For this purpose the outer end of the handle is formed as a telescoping sleeve 76 surrounding an inner tubular portion 78. A rod 80 ex tends through the tubular portion and is surrounded by a spring 82 which urges the end 76 of the handle outward to an extended operating position. When the sleeve 76 is pressed inward against the action of spring 82, it may enter the

enlarged end

66 or 68 of the slot and since sleeve 76 is larger in diameter than the width of the oiIset, portions. 70 and '72 of the slot, the handle cannot be moved in an arcuate manner as long as sleeve 76 is cqmplfessed and extends into one or the other of the enlattgcd. openings- 66 or 68.

The sleeve 76 may be held in its compressed or, locking position by any suitable type of: releasable means. shown, the outer sleeve 76 is provided with a collar 84 surrounding rod 80 and movable axially of the rod into and out of engagement with a stop 86 formed on the end of the rod. Locking balls or dogs 88 are located in radial bores 90 near the outer end of the collar 84 and are movable into locking position beneath the stop 86 when the sleeve 76 is compressed against the action of spring 82 so as, to enter one of the

enlarged openings

66 and 68 in theslot 60.. A cap 92 which isslidably fitted over the end of collar 84 serves to hold the locking balls in their inner locking position to retain the handle in its depressed and locked position in opening 66 or 68. The cap is urged outward to hold the locking balls in place by means of a spring 94. However, the. cap is tormedwith an annular recess 96 sothat when the cap isdepressed against the action of spring. 94, the balls can moveoutward from beneath, the stop 86 .whereupon, the collar and outer end of the handle will move ohtward underthe action of spring 82 to an extended operating position. The lower end of sleeve 76 will then be withdrawn from the

enlarged opening

66 or 68 so as to release the handle for arcuatemovement to actuate the

harness connectors

10, 12, 20 and 22. In the preferred form of the invention illustrated, the cap 92 is limited in its outward movement by engagement with member 98 and is enclosed within a rubber or flexible cover 100 so that a watertight and dust-proof assembly is provided.

The axial or radial movement of the outerend of the handle to an extended operating position not only serves as a visual indication of the operative condition of the actuating means, but also serves to present the handle in a more prominent and convenient position wherein it projects above the chest pack 32 carried by the harness. The increased length ofthe handle also gives more leverage for operating the actuating means in the event any of the connectors should prove difficult to operate. 0n the other hand, when the handle is in its collapsed locking position, the end 100 is positioned near the upper side of the chest pack 32 where it will be out of the way and protected by the chest pack but still be located in position tobe readily pressed or struck by the fist to release the handle for operation.

In using the parachute harness described, the wearer moves the handle 56 of the actuating device 34 to its central or loading position in which the handle is located in the transverse channel 74 of slot 60 between the oifsetportions 70 and 72 of the slot. Such positioning of the handle serves to pull on cables 42 sufliciently to move the slide 40 of each of the

connectors

10, 12, 20 and 22 against the action of spring 44 and to an intermediate or loading position in which the latching elements 38 are freed to permit insertion of the

links

4 and 24 into openings in the body 36 of each connector. Since the handle will normally tend to remain in the loading position until positively moved, the wearer may use both hands in applying and adjusting the harness.

In applying the harness to the wearer, the chest piece 18 carrying the actuating device is attached to the shoulder portions of the harness by pushing links 24 into

connectors

28 and 22. Loops 8 of the leg straps are slipped over the ends of the seat portion 2 and the links 4 on the ends of the seat portion are pushed into

connectors

10 and 12. The latching elements 38 of the various connectors snap into engagement with the links under the action of springs 46 affording an audible indication that they have become engaged. The connector may further be provided with transparent covers if desired so that the condition of each connector can be inspected to insure proper connection of the parts connected to the seat portion 2 by the links 4.

The handle 56 is then moved to its locking position in the enlarged opening 66 at the end of the portion 70 of slot 60 and the outer telescoping end of thehandle is pushed inward against the action of spring 82 until it enters the opening 66. In pushing the end of the handle inward, cap 92 is depressed so that the annular recess 96 therein is aligned with bores 90 in collar 84. The locking balls 88 can therefore move outward into the recess 96 allowing the stop 86 on rod to pass the locking balls. Thereafter upon release of the rod, the cap 92 is moved outward by spring 94 and the locking balls are, pushed inward so as to project beneath the stop 86 to the position shown in Fig. 3. The outer end of the handle 56 is thus held depressed and locked within the opening 66 in slot 60 preventing rotary or arcuate movement of the handle. Cover flaps 102 may be secured to the base '50 of chest piece 18 and are foldable inward to engage snaps 104 to protect the elements from injury or exposure.

When the wearer descends in a parachute jump, and upon approaching the ground, it is only necessary to press upon the cover 100 on the outer end of the handle or to strike it with a blow of the gloved hand, whereby the cap 92 will be depressed to bring the annular recess 96 into position to receive the locking balls 88. The balls will then move outward allowing the sleeved end 76 of the handle to move outward under the action of spring 82 withdrawing the sleeve from opening 66 of the slot 60. The outer end 76 of the handle is then free to move outward from its collapsed and protected position to a prominent exposed operating position wherein it may be readily moved to rotate the drum 52 so as to cause the cables 42 to be pulled. If desired, the handle 56 may be pushed along the ofiset portion 70 of slot 60 to the transverse channel 74. The actuating device is then readied for a final releasing movement upon landing.

When the parachutist lands it is only necessary to move thehandle through the channel 74 of slot 60 and on through ofiset portion 72 of the slot to the opposite opening '68. When so moved, the cables 42 are pulled sufficiently to withdraw the latching elements 38 from engagement with the

links

4 and 24 so that the chest piece is disconnected from the harness. The chest piece, leg straps, seat portion and shoulder portions of the harness are then all released and the harness will fall away from the wearer freeing him for normal activity.

The handle portion 76 may be depressed to engage opening 68 in slot 60 to lock the actuating device in releasing position when not in use so that it will not return accidentally to a locking position until positively released and moved.

The connectors employed may, of course, vary considerably in form and construction, but have here been described as being of the type shown in copending application Serial No. 479,566 since such connectors are typical of those which have been employed in such assemblies. The harness chosen for purposes of the present description is that of Patent No. 2,726,832 but it will be apparent that other types of quick release harness and other types of connector releasing means may be used if desired. It should therefore be understood that numerous changes and modifications may be made in the form, construction and arrangement of the various elements of the actuating device employed, and accordingly the particular embodiment of the invention shown in the drawings and described above is intended to be illustrative only and is not intended to limit the scope of the invention.
