12 Claims. (Cl. 9-342) ABSTRACT OF THE DISCLOSIRE A buoyant jacket formed of a resilient buoyant substance disposable about the chest of the wearer to support the wearer in the water with his head above the water and tilted rearwardly.
This application is a continuation-in-part of my copending application, Ser. No. 548,129, filed May 6, 1966, now Patent No. 3,360,814.
This invention relates to sporting equipment and more particularly to buoyant jackets.
An object of this invention is to provide a new and improved buoyant or life jacket for supporting the wearer thereof in the water.
Another object is to provide a life jacket which is comfortable to wear.
Another object is to provide a new and improved life jacket for protecting the wearer from injury when the wearer strikes water with relatively great force, as when falling while being towed at a relatively high speed on water skis.
Still another object is to provide a life jacket which is resilient to conform to the chest of the wearer and grip the chest through substantially its whole area whereby the jacket cannot move relative to the chest to impart a blow thereto when the wearer strikes the water with relatively great velocity and force.
A further object is to provide a life jacket formed of a buoyant substance having a greater volume of a buoyant substance in the front than in the back so that it will cause the wearer to float in a rearwardly inclined position to hold the wearers head out of the water and his face facing upwardly.
A still further object is to provide a life jacket having a body portion formed of a flat sheet of resilient shock absorbent buoyant substance which when disposed about the chest of the wearer assumes an arcuate shape with the internal cross sectional area of the life jacket being inherently smaller than the area of the chest of the wearer, the vertical edges of the body portion being provided with fastening means for drawing the edges of the body portion toward and into close proximity to one another whereby the body portion may be stretched resiliently about the chest of the wearer and cause the body portion to firmly grip the chest.
A further object is to provide a life jacket wherein buoyant inserts or pads are disposed in the front portion of the flat sheet to add buoyancy to the front portion of the jacket.
Another object is to provide a life jacket wherein the body portion at the adjacent vertical edges thereof is provided with outwardly opening recesses in which are disposed the fastening means, such as straps and buckles, so that the adjacent edges may be positioned close to one another and the buckles prevented from contacting the body of the wearer.
Still another object is to provide a life jacket having shoulder straps connected to the body portion which limit downward movement of the jacket on the body of the wearer.
3,400,415 Patented Sept. 10, 1968 Still another object of the invention is to provide a life jacket having reinforcing means secured to the body portion, the reinforcing means including two non-elastic flexible front reinforcing assemblies embedded in the front sections of the body portions, the fastening means of the jacket being secured to the reinforcing assemblies.
A still further object is to provide a life jacket where the body portion is provided with slots to provide greater elasticity to the rear or back portion thereof to cause the jacket to have a relatively great buoyant volume thereof disposed in its front portion as compared with its rear portion without causing the front portion to be of excessively great thickness, and to provide for air flow between the exterior and the interior of the jacket.
A still further object is to provide a life jacket having slots in its rear portion through which water may flow outwardly when the wearer thereof falls forward into the water to minimize the stress and strains to which the life jacket is subjected.
A still further object is to provide a life jacket wherein the assembly of the body portion, the inserts and the reinforcing assemblies is covered with a water impervious resilient coating.
Additional objects and advantages of the invention will be readily apparent from the reading of the following description of a device constructed in accordance with the invention, and reference to the accompanying drawings thereof, wherein:
FIGURE 1 is a perspective view of a life jacket embodying the invention;
FIGURE 2 is a back view of the life jacket;
FIGURE 3 is an exterior view of the jacket with the jacket disposed in a flattened position;
FIGURE 4 is a sectional view taken on line 4--4 of FIGURE 3;
FIGURE 5 is a sectional view taken on line 55 of FIGURE 2;
FIGURE 6 is an exploded view of the components of the life jacket as viewed from the front with some portions thereof broken away;
FIGURE 7 is an exploded view of the components of the life jacket as viewed from above; and
FIGURE 8 is a perspective view of one of the auxiliary buoyant inserts or pads of the life jacket.
Referring to the drawings, the life jacket 20 embodying the invention includes a body portion formed of a flat sheet 22 of a resilient shock-absorbing buoyant substance, such as unicellular vinyl or rubber foam having numerous small voids or cells which render the density of the life jacket much lower than the density of water. The sheet, which may be of a suitable thickness, for example, threequarter or one inch thick and, has a back portion or panel 23, side portions or panels 24 and 25, and right and left front portions or panels 26 and 27, respectively. The front panels 26 and 27 have upper extensions 28 and 29 respectively, whose rear edges 31 and 32 together with the top edges 33 and 34 of the side panels 24 and 25 and the side edges 35 and 36 of the upper portion of the back panel define the upwardly opening right and left arm holes or recesses 37 and 38 for receiving the arms of the wearer.
The flat sheet has a vertical side slit 40 which extends inwardly from its right edge 42 and divides the right front panel into an inner section 43 and an outer section 44. A floatation pad 45, which is of the same substance as the flat sheet 22, is inserted in the slit between the inner and outer portions 43 and 44, its inner planar surface 47 being secured to the inner surface of the inner portion 43 by a suitable adhesive or bonding agent. The floatation pad has an outer planar surface 48 which extends parallel to its inner surface 47 and a vertical inner surface 49 which extends inwardly from the inner end of the outer flat surface 48 to the inner vertical edge 50 of the pad.
The upper outer surface 52 of the pad extends upwardly and inwardly from the top edge of the outer surface 48 to its top edge 53. The left front panel of the sheet similarly is divided into inner and outer portions 55 and 56, respectively, by a slit 57 between which the left floatation pad or insert 45a is insertable.
The insert 45a is a mirror image of the insert 45, and, accordingly, its elements have been provided with the same reference numerals, to which the subscript a has been added, as the corresponding elements of the pad 45.
The outer portion 56 of the left front panel is provided with three recesses 61, 62, and 63 in which are positioned the buckles 64, 65, and 66 respectively of a left reinforcing assembly 70. The left reinforcing assembly 70 is disposed between the outer surface 48a of the left pad 45a and the inner surface of the outer portion 56 and includes a substantially rectangular piece or panel 71 of nylon fabric to which are secured three buckle straps 72, 73 and 74 by means of stitches 75. The outer end portions of the straps extend about the central bars 76 of the buckles and are secured to their intermediate portions by means of rivets 77. The reinforcing assembly is secured to the left panel in such a manner that the buckles are disposed in the outwardly opening recesses 61, 62 and 63 outwardly of the outer surface of the portions of the left pad 45a exposed at these recesses.
A right reinforcing assembly 80 disposed between the outer surface 48 of the right pad 45 and the inner surface of the outer portion 44 of the right front panel 26 includes a substantially rectangular panel or piece 81 of nylon fabric to which are secured the inner end portions of straps 82, 83 and 84 by means of rows of stitches 85. The outer portions of the straps 82, 83 and 84 are insertable to the front buckles 64, 65 and 66, respectively, to draw the edges of the jacket toward one another when the jacket is disposed about the chest of a. wearer. The reinforcing assemblies are secured to the pads and the inner surfaces of the outer portions of the front panels by a suitable adhesive or bonding agent.
A right shoulder strap 91 of the jacket which is also formed of the same substance as the sheet has a front downwardly facing end surface 92 which is secured to the upwardly facing upper surface 93 of the right front panel and a rear end surface 94 which is secured to the upwardly facing surface 95 of the back panel 23. Similarly, the left shoulder strap 97 has a front downwardly facing end surface 98 which is secured to the upwardly facing upper surface 99 of the left front panel and a rear end surface 100 which is secured to the upwardly facing surface 101 of the back panel. The straps are secured to the body sheet by an adhesive or bonding agent.
The body sheet 22 is provided with a plurality of left vertically spaced horizontal slots 105 which extend from locations spaced to the left of the center line of the back panel to locations below the left arm hole 38 of the jacket and the left floatation pad 45a is provided with recesses 106 at the location of its alignment with the front end portions of the slots. The body sheet is also provided with a plurality of right vertically spaced horizontal slots 110 which are aligned with the horizontal slots 105 and which extend from locations spaced to the right of the center line of the back panel to locations below the right arm hole 37 of the jacket. The right floatation pad 45 is provided with recesses 111 at the locations of its alignment with the front end portions of the slots 110. The slots 105 and 110 and the recesses 106 and 111 of the floatation pads may be cut out before the insertion of the pads between the inner and outer portions of the front panels or the slots and recesses may be-formed after the floatation panels have been secured to the body sheet.
In the manufacture of the life jacket, the floatation pads 45 and 45a are first inserted in the slits 40 and 57, respectively, the outer portions 44 and 56 of the left and right front panels flexing outwardly to the positions illustrated in the drawings due to the provision of the beveled surfaces 49 and 49a on the floatation pads. As a result, the thickness of the jacket begins to increase at locations at approximately the center lines of the two arm holes and the jacket therefore does not unduly hinder natural movement of the arms of the wearer. The pads are then secured to the inner portions of the front panels of the body sheet. The reinforcing assemblies 70 and 80, the assembly 70 without the buckles 64, 65 and 66, are then positioned as illustrated in the drawings and are secured to the floatation pads and to the inner surfaces of the outer front panel portions 48 and 56 by an adhesive or bonding agent. The contacting surfaces of the outer portions of the front panels and the pads not in alignment with the rectangular panels 71 and 81, are also secured to one another by such adhesive or bonding agent. The right and left shoulder straps 91 and 97 are then secured to the body sheet. The assembly of the body sheet, the floatation pads, the reinforcing assemblies of the shoulder straps is then coated with a coat of 115 of plastic resilient substance, such as vinyl, rubber or the like. The coating may be of the same substance as the substance of which the body sheet, floatation pads and the shoulder straps are formed except that it is not unicellular but solid in form. Since all elements of the jacket, except the reinforcing assemblies, are resilient, the portions of the life jacket between the reinforcing assemblies may be stretched resiliently. The outer end portions of the straps 72, 73 and 74 are then looped above the middle bars of the buckles 64, 65 and 66, respectively, and their free ends are then secured to intermediate portions thereof by means of rivets.
In use, the wearer inserts his arms through the arm holes 37 and 38. The internal cross sectional area or space defined by the internal surface of the life jacket is smaller than the chest of the wearer when the jacket is in its inherent non-stretched condition so that its vertical edges are spaced tWo to six inches apart when the jacket is placed on the wearer. The straps 82, 83 and 84 of the right reinforcing assembly are then inserted through the buckles 64, 65 and 66, respectively, and the vertical side edges of the life jacket are then drawn toward one another to the degree necessary to resiliently stretch the life jacket about the chest of the wearer and bring its vertical edges close to or in contact with one another. This stretching of the life jacket about the chest of the wearer is facilitated by the provision of the slots 105 and 110 which increase elasticity of the jacket at its back portion. The buckles, which are positioned in the recesses of the outer portion 56 of the left panel of the body sheet 22, are now precluded from contacting the body of the wearer since the thickness of the left floatation pad 45a and the inner portion 55 of the body chest is interposed between the buckles and the chest. The slots 105 and 110 facilitate flow of air between the exterior and the interior of the jacket thus making the jacket comfortable to wear.
The life jacket is now stretched resiliently about the chest of the wearer and engages it firmly so that no portion of the jacket is loose on or spaced from the chest. Any loose portion of the life jacket would tend to strike the wearer if the wearer fell with great force into the water. Should the wearer now fall with relatively great velocity and force forwardly into the water, as is quite likely to occur if the wearer is water skiing, any water flowing into the jacket between the wearers chest and the life jacket will tend to flow rearwardly therefrom and if the slots 105 and 110 were not provided would tend to exert a relatively great rearward force on the rear portion of the jacket which would tend to rip or break the jacket. The provisions of the slots 105 and 110 permits such water to flow outwardly therethrough and this minimizes the stresses and strains to which the jacket is subjected. As a result the jacket may be made of a relatively soft uni-cellular material so that it is comfortable to wear and still is capable of resisting the stresses and strains imposed thereon when the wearer falls into the Water.
It will now be seen that a new and improved life jacket has been illustrated and described which can be easily and quickly placed about the chest due to the provision of the slots in the rear portions of the body of the life jacket and that the greater portion or volume of the buoyant substance is located at the front portion of the body of the wearer in water in a rearwardly and upwardly inclined position with the face of the wearer facing upwardly.
Ilgwill further be seen that the life jacket includes a body portion formed of a flat body sheet 22 provided with vertical slits in its side edges in which are disposed auxiliary flotation pads or inserts to add buoyancy to the front portions of the jacket.
it will further be seen that the body portion is provided with a plurality of horizontally extending vertically spaced slots 105 and 110 which together extend through substantially or approximately one half of the total length of the body portion and in the portions thereof which lie rearwardly of the center of gravity of the wearer thereof to reduce the buoyancy of these portions of the body and thus further increase the degree to which the life jacket of the wearer is inched upwardly and rearwardly by the jacket. It will further be seen that these slots 105 and 110 increase the elasticity of the body portion so that the jacket may be easily stretched about the chest of the wearer and provide for the flow of air and water between the exterior and interior of the jacket to make the jacket more comfortable to wear by providing some ventilation between the chest and the jacket and permitting escape of liquid rearwardly from between the chest and the jacket in the event the wearer falls forwardly into the water.
The foregoing description of the invention is explanatory only, and changes in the details of the construction illustrated may be made by those skilled in the art, within the scope of the appended claims, without departing from the spirit of the invention.
