Abstract

A parachute with enhanced pocket bands positioned adjacent the points of securement of suspension lines and radial lines with respect to the lower edge of the canopy of the parachute wherein the pocket bands are oriented angularly with respect to the radial lines and with respect to the direction of flow during initial inflation of the parachute in order to enhance inflation of air pockets between the pocket bands and the external surface of the canopy adjacent the radial lines in order to more rapidly inflate the canopy of the parachute to facilitate use thereof at lower altitudes and to provide a more controlled canopy inflation. Pocket bands are attached to the lower canopy edge at an angular relation thereto such that the bands catch significantly more air than in the prior art design in order to facilitate inflation of the pocket bands and achieve rapid controlled inflation.

Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention deals with the field of parachutes and other aerial descent control mechanisms and, in particular, in regard to designs for the purpose of more rapidly and in a more controlled manner achieving inflation of the canopy of such parachutes. The use of pocket bands positioned attached adjacent at least some of the radial lines between adjacent gores of the canopy have been utilized heretofore. The present invention provides a unique configuration for such pocket bands which orients them angularly with respect to the radial lines and with respect to the movement of air which causes inflation of the canopy in order to enhance lateral movement of the lowermost edge of the canopy to a more rapidly and in a more controlled manner inflate the parachute. This improved configuration for the pocket bands allows more efficient and reliable canopy inflation than with pocket bands utilized heretofore.

SUMMARY OF THE INVENTION

The present invention provides an enhanced pocket band configuration for use with a parachute in order to control and speed initial inflation thereof. This improved parachute design includes a canopy adapted to be inflated to provide controlled descent for a load attached thereto. The canopy preferably includes an inner surface defining an inflation chamber therein and an outer surface about the exterior area thereof oppositely located from the inner surface.

The canopy further includes a lower edge being generally circular in shape and extending peripherally around the parachute. Preferably, a apex opening or canopy vent is defined by the canopy at the uppermost point or apex thereof.

A plurality of suspension lines are attached to the lower edge of the canopy and extend downwardly therefrom for attachment selectively to a load therebelow. A load attachment device such as risers or the like can be attached to the suspension lines in order for detachably securing a load thereto for providing controlled aerial descent thereof.

A plurality of radial lines extend along the canopy from the apex opening or canopy vent to the lower edge thereof. Usually these radial lines are attached to the lower canopy edge at locations where suspension lines also extend downwardly therefrom. The radial lines are attached along the length thereof to the adjacent surface of the canopy. A plurality of gores are defined in the canopy adjacent the lower edge thereof between each pair of the radial lines.

The upper ends of the radial lines terminate at the lowermost edge of the apex opening. Vent lines extend across the apex opening from the lowermost edge thereof. To facilitate distribution of forces, it is preferred than these vent lines be freely movable relative to one another, thus normally they are not secured to one another as they cross over one another in the apex opening area.

A pocket band is attached preferably to the outer surface of the canopy at every gore, or, in some configurations, at every other gore. The means of securement can be by any conventional manner such as adhesives or by being sewn in place to the adjacent members or surfaces. Each of these pocket bands preferably includes a first end fixedly secured to the outer surface of the canopy adjacent one of the gores at an acute angle relative to the radial line secured thereto. The pocket band further also preferably includes a second end fixedly secured by adhesive or being sewn to the outer surface of the canopy adjacent the gore and spatially disposed from the first end and the second end and secured to the canopy preferably at an acute angle relative to the radial line secured at that point.

A central band section of the pocket band is included which can be formed with a width of any reasonable dimension which should be proportional to the parachute diameter. A width of approximately two inches has been found to be preferred for most moderate sized parachutes. This central band section is secured at one end to the first end means and at the other end to the second end means and is not attached in any manner with respect to the canopy such that it is freely movable away from the canopy to enhance forming of an inflation pocket therebetween. The first end and the central band section and the second end of each of the pocket bands can preferably comprise a single integral member of any flexible material, however usually they will be formed of a woven fabric. The central band section is defined to extend between the first end and the second end across an adjacent radial line therebetween and be oriented angularly with respect thereto.

The central band section is preferably movable away from the gore of the canopy to be oriented at an angle extending downwardly and outwardly relative to the radial line thereadjacent in order to facilitate defining of an inflation pocket therebetween. This inflation pocket is designed to receive air moving thereinto during initial inflation of the canopy to facilitate initial deployment thereof. The inflation pocket is adapted to be inflated during the initial inflation of the canopy in such a manner as to urge outward movement of the lower edge of the canopy in order to aid initial inflation thereof. The central band is positioned angularly with respect to the radial line thereadjacent in order to increase the surface area of the central band section oriented perpendicularly to the direction of flow of inflating air during initial inflation of the canopy in order to facilitate defining of the inflation pocket adjacent the gores for more rapidly expanding of the canopy to achieve controlled initial deployment thereof.

The central band section of the pocket band may preferably also include an upper band segment extending between the first end means and the second end means as well as a lower band section also extending between the first and second end means. The lower band segment is preferably of a greater length than the upper band segment in order to allow the central band section to be oriented angularly with respect to the relative direction of movement of air during initial inflation of the canopy. The upper band segment and the lower band segment are preferably formed as a single integral member of woven fabric or other flexible material.

With this construction the central band will preferably be generally of a trapezoidal shape and define a first parallel side and a second parallel side each being parallel with respect to one another with the second parallel side being longer than the first parallel side to facilitate defining of the trapezoidal shape. The first parallel side is preferably positioned on the upper band segment and the second parallel side is positioned on the lower band segment to allow outward flaring of the lower band segment relative to the upper band segment to facilitate defining of an inflation pocket adjacent the lower edge of the canopy for the purposes defined above.

First angular stitching is preferably included for attaching of the first end to the canopy at an acute angle relative to the radial line thereadjacent to facilitate orienting of the central band section angularly relative to the movement of the inflating air. This configuration is for the purpose of urging inflation of the inflation pocket thereadjacent during initial inflation of the canopy. The first angular stitching will preferably include a first inner stitching seam immediately adjacent the central band section and basically forming the interface between the central band section and the first end. In this manner the first inner stitching member will facilitate orientation of the central band section relative to the radial lines at an angle in order to increase the lifting force vector thereon resulting from air movement relatively parallel to the radial lines during initial inflation of the canopy and prior to full inflation thereof.

In a similar manner, a second angular stitching will preferably be included for attaching the second end to the canopy at an acute angle relative to the radial lines to facilitate orienting of the central band section angularly relative to the movement of inflating air in order to urge inflation of the pocket thereadjacent. The second angular stitching preferably includes a second inner stitching seam immediately adjacent the central band section to facilitate orientation thereof angularly relative to the radial lines to increase the lifting force vector thereon resulting from air movement relatively parallel to the suspension lines during initial inflation of the canopy and prior to full inflation thereof. For stability, it is preferable that the pocket band and the angular attachment, which may comprise stitching, forming the pocket band be oriented symmetrically about the adjacent radial line, when viewing radially inwardly thereon.

It is an object of the present invention to provide a parachute with enhanced pocket bands to facilitate controlled initial inflation thereof wherein inflation pockets are more easily formed at each parachute gore to facilitate canopy inflation.

It is an object of the present invention to provide a parachute with enhanced pocket bands to facilitate controlled initial inflation thereof wherein conventional parachute materials can be utilized.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

The present invention provides a parachute 10 with a canopy 12 which is generally circular. Canopy 12 defines an inner surface 14 which defines an inflation chamber 18 therein and an outer surface 16 oppositely positioned from the inner surface 14 .

A lower edge 20 is defined along the bottommost area of canopy 12 and a plurality of radial lines 23 are secured to the canopy 12 . Radial lines 23 extend from apex opening or canopy vent 13 to the lower edge 20 and define gores 24 therebetween. Suspension lines 22 are attached to radial lines 23 and extend past the lower edge 20 of the canopy. A load attachment means 26 which can comprise risers can preferably be located therebelow and be attached to the lower portion of suspension lines 22 . Load attachment means or risers 26 can be detachably securable to a load 27 for providing controlled aerial descent thereof. Use of the load attachment means 26 is optional since the suspension lines 22 can be secured directly to a load 27 under in certain applications of the parachute system of the present invention.

The canopy 12 includes the plurality of radial lines 23 extending from the canopy vent or apex opening 13 to the lower edge 20 thereof. A vent 13 can be located in canopy 12 in the areas of the apex 19 or uppermost location thereon. A plurality of gores 24 are included each located between adjacently positioned radial lines 23 and extending therebetween. Suspension lines 22 are attached to each radial line 23 at the canopy lower edge 20 and extend downwardly therefrom. The individual radial lines 23 and the specifically associated suspension line 22 can each be constructed as a single integral line in some parachute designs without affecting the function of the present invention.

In the preferred configuration of the present invention a pocket band 28 is secured by adhesive or stitching to the outer surface 16 of the canopy 12 of the present invention in such a manner as to extend over the radial line 23 secured thereadjacent. This pocket band 28 preferably includes a first end 30 secured to the outer surface 16 of the canopy 12 and a second end 32 secured to the outer surface 16 of the canopy 12 on the opposite side of the radial line 23 from the first end 30 . Thus, with first end 30 secured to the canopy 12 on one side of the radial line 23 and the second end 32 secured on the opposite side thereof, the pocket band 28 will extend across radial line 23 secured to the lower edge 20 of canopy 12 .

The first end 30 and the second end 32 of the pocket band 28 of the present invention are connected with respect to one another by a central band section 34 . It is this central band section 34 which extends from the gore 24 on one side of the radial line 23 to the adjacent gore 24 on the other side thereof. In this invention the central band section 34 will be oriented vertically at an angle relative to the radial lines 23 and with respect to the canopy 12 . This angular orientation is for the purpose of having the central band section 34 provide a greater cross section of wind resistance which is impinged upon by the relative upward movement of air with respect thereto during inflation.

As best shown in FIGS. 6 and 7 , air will force the pocket band 28 away from the lower edge 20 of canopy 12 when the pocket band 28 is in close proximity to the lower edge 20 during the initial stages of inflation. At this point, the aerodynamic forces are helping to move the pocket band 28 away from close contact with the lower edge 20 of canopy 12 so that the pocket band 28 will assume the orientation shown in FIGS. 3 , 4 , and 5 , and still later, will assume the orientation shown in FIG. 2 after the canopy becomes fully inflated. The angle of the adhesive attachment or stitching 38 and 42 will help to orient the pocket band 28 as shown in FIG. 3 , thus avoiding the undesirable orientation shown in FIG. 8 . For the purpose of this preferred embodiment only, stitching 38 and 42 will be described as the means of attachment of the pocket bands 28 to the adjacent surface but attachment utilizing standard adhesives used in this field of art is also within contemplation of the present invention. As a result of this geometry when the pocket band 28 is in close proximity to the lower edge 20 as shown in FIG. 8 , the aerodynamic forces are not effective in moving the canopy 12 radially outwardly for encouraging full inflation thereof. As the pocket bands 28 move as shown in FIGS. 4 , 5 and 6 , they will be stretching outwardly due to the aerodynamic forces. Tension will then be applied to canopy 12 by pocket bands 28 thereby urging the lower edge 20 of canopy 12 to move radially outwardly. The angled stitching 38 and 42 serves to promote this specific function of each pocket band 28 .

In order to angularly orient the pocket band 28 and, in particular, the central band section 34 thereof relative to the canopy 12 and the radial lines 23 and the relative air direction movement 48 , a first angular stitching 38 is utilized. The configuration of this stitching is shown best in FIG. 6 and makes use of a first inner stitching seam 40 at the intersection between the central band section 34 and the first end 30 . In a similar manner a second angular stitching 42 is utilized at the second end 32 for securement thereof with respect to the canopy 12 and utilizes a second inner stitching seam 44 angularly oriented relative to the lower edge 20 of the canopy 12 in order to encourage movement of the central band section 34 away from abutment with the lower edge 20 of the canopy 12 to facilitate defining of the inflation pocket 29 relative to the outer surface 16 of canopy 12 .

With this stitching configuration of the first inner stitching seam 40 and second inner stitching seam 44 , the central band section 34 will be formed in the general shape of a trapezoid 46 . This trapezoidal shape 46 will include a first parallel side 58 along the upper band segment 54 of the central band section 34 . In a similar manner the trapezoidal shape 46 will dictate the lower band segment 56 of the central band section 34 to define a second parallel side 60 . First parallel side 58 will be smaller than second parallel side 60 thereby causing an angle 36 to be created between the adjacent radial line 23 and the inner stitching seams 40 and 44 . This configuration for the pocket band 28 will encourage the lower band segment 56 of the trapezoidal shaped central band section 34 to flare outwardly and assume an acute angle 52 in relation to the relative direction of movement of air shown by arrows 48 to enhance the possibility of immediate full inflation of an inflation pocket 29 adjacent each of the gores 24 .

The vertical or lateral dimension of the pocket band is critical because it is this dimension which determines the cross sectional area against which the relative air flow 48 will contact. The width or vertical height 50 of the pocket band 28 is preferably approximately two inches. The width of the band 28 can be much wider than two inches for larger canopy diameters and can be much narrower for smaller ones. However, the relationship between canopy size and the width of band 28 is an important aspect of the present invention.

A prior art configuration is shown in FIG. 13 wherein the prior art pocket band 62 is shown along a prior art lower canopy edge 64 adjacent a prior art suspension line 66 . With this configuration it can be seen that the inner seam of the stitching on each end of the pocket band is parallel with respect to one another and parallel to the radial lines and the direction of movement of air during initial inflation thereof. Also, this stitching, which is perpendicular to the lower edge of the canopy, defines a central band section of the pocket band which is rectangular in shape rather than trapezoidal and thereby is not oriented angularly with respect to the radial lines as in the present invention. For this reason the present invention is a distinct improvement thereover for the reasons described above regarding the advantages of the angular relationship of the central band section 34 relative to the direction 48 of relative inflating air movement.

In summary, the angled stitch pattern of the present invention orients the pocket band in such a manner as to be angularly oriented relative to the radial lines defining the canopy profile. The pattern also provides this angular relationship relative to the canopy skirt and, most importantly, relative to the air flow during initial stages of inflation. This angular orientation generates a lift component that will force the canopy skirt outwardly in order to more rapidly and reliably inflating the canopy skirt. This is achieved by the force exerted on each pocket band outwardly and away from the canopy which allows the pocket band to have a propensity to assume the configuration shown in FIG. 3 much more often than assuming the collapsed configuration shown in FIG. 8 .

As shown in the figures, the detailed structure of the apparatus of the present invention includes radial lines 23 which are the structural members that transfer loads from suspension lines 22 into the canopy 12 . Radial lines 23 are secured to the fabric portion of canopy 12 , and generally extend from the lower edge 20 thereof to vent 13 . The band extending about the edge of the vent is the member in combination with the overall canopy configuration and the radial lines together distribute the load along the desired paths. It should be appreciated that in accordance with the present invention, it is contemplated that the radial lines 23 the suspension lines may be separate elements or may each comprise a single integral member or continuous line. Each gore 24 is separated from an adjacent gore 24 by a radial line 23 . The lowermost section of a gore 24 is defined by canopy lower edge 20 .

While particular embodiments of this invention have been shown in the drawings and described above, it will be apparent, that many changes may be made in the form, arrangement and positioning of the various elements of the combination. In consideration thereof it should be understood that preferred embodiments of this invention disclosed herein are intended to be illustrative only and not intended to limit the scope of the invention.
