' HZ 9 4 {OZ leanara E'ieaer J7 HTTORNEYS BACKGROUND OF THE INVENTION Many and various forms of buoyant jackets or vests are known in the prior art. Many of these jackets comprise a plurality of bodies of buoyant material which are connected together and which are releasably held in position on the wearers person. Some of the jackets are provided with means for drawing adjacent front edges of buoyant bodies together to pull the jacket more closely around the wearer. The rest of the jacket structure comprises means for securing other respective edges of the jacket to each other. These other securing means include at least one permanent nonadjustable connection and other connections which may comprise adjustable elements. such elements, however, if provided, are accessible only at the locations at which they are installed.

In use of jackets of the prior art of the type described, the user, before donning the jacket, may make some side or back rough adjustment if such adjustment is provided. Then, after having donned the jacket he may actuate the front adjusting elements to draw the jacket closely around his person. In so doing, however, while the front edges are drawn together the distance between the other edge or edges at which the buoyant bodies are connected does not change so that in effect the positions of these bodies on the wearers person shift. While the jacket might still function fairly satisfactorily in such a circumstance, it is not as comfortable as is desired. Owing in part to the fact that a permanent connection is provided in at least one area, if a relatively wide range of adjustment is provided the problem is aggravated and the jacket may not function as effectively as intended.

I have invented a buoyant jacket which "overcomes the problemof buoyant jackets described hereinabove. My jacket may be drawn closely about the wearer's body without shifting the positions of the buoyant bodies with relation to the wearer's person. My adjustable buoyant jacket is comfortable. It affords a wide range of adjustment while being comfortable and effective in all adjusted positions.-

SUMMARY OF THE INVENTION One object of my invention is to provide an adjustable buoyant jacket which overcomesthe defects of adjustable buoyant jackets of the prior art.

Another object of my invention is to provide an adjustable buoyant jacket which is comfortable in all adjusted positions thereof.

A further object of my invention is to provide an ad.- justable buoyant jacket which affords a wide range of adjustment while not interfering with the effectiveness of the jacket.

Still'another object of my invention is to provide an adjustable buoyant jacket which can be drawn closely about the wearer's person without shifting the buoyant masses making up the jacket.

In general my invention contemplates the provision of an adjustable buoyant jacket comprising right-hand and left-hand buoyant masses having adjacent front edges and adjacent back edges with manually readily actuatable means at the front of the jacket for concomitantly adjusting the distance between the front edges and the distance between the back edges of the buoyant masses in the waist region and adjustable means connecting the back edges in the shoulder region.

BRIEF DESCRIPTION OF THE DRAWINGS In the accompanying drawings which form part of the instant specification and which are to be read in conjunction therewith and in which like reference numerals are used to indicate like parts in the various views:

FIG. 1 is a plan view of the outside of my adjustable buoyant jacket with the parts thereof laid out flat.

FIG. 2 is a plan view of the inside of my adjustable buoyant jacket with the parts thereof laid out flat.

FIG. 3 is a front elevation of my adjustable buoyant jacket in position on the person of a wearer.

FIG. 4 is a sectional view of my adjustable buoyant jacket taken along the line 4-4 of FIG. 3 and drawn on an enlarged scale.

DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now to the drawings my improved adjustable buoyant jacket indicated generally by the reference character 10 includes a left-hand unit, indicated generally by the reference character 12 comprising a waist portion 14, a chest portion 16, a back 18, a front shoulder portion 20 and a rear shoulder portion 22. The unit 12 may be made upof a mass 24 of any suitable buoyant material such for example as a unicellular foamed plastic. I enclose the mass 24 man envelope including an outer fabric 26 and an inner mesh fabric 28 which fabrics are joined around the edge of the unit by beading 30. Preferably the outer fabric 26 is a very closely woven fabric which is water repellent. The inner fabric 26 is an openwork fabric such as a mesh or a relatively loosely woven'fabric which permits water and air to pass freely therethrough both to prevent water from being trapped inside the envelope as well as for ventilation.

My jacket 10 also includes a right-hand unit indicated generally by the reference character 32 which includes a waist portion 34, a chest portion 36, a back portion 38, a front shoulder portion 40 'and a rear shoulder portion 42. The unit 32 is made up of a mass 44 of unicellular foamed plastic or other buoyant material enclosed in an envelope made up of an outer panel 46 of closely woven fabric and an inner panel 48 of openwork fabric which panels are joined at the edges by beading 50 to complete the envelope.

First, I provideadjustable means for connecting the front shoulder portion 20 to the rear shoulder portion 22 and adjustable means for connecting the front shoulder portion 40 to the rear shoulder portion 42 to form the armholes of the jacket. Specifically, I stitch a length 52 of nylon webbing or the like to the upper end of shoulder portion 20. A length 58 of webbing stitched or otherwise secured to the upper end of shoulder portion 22 forms a loop for receiving a pair of

rings

54 and 56 through which the webbing 52 passes topermit adjustment of its effective length. This is achieved in a manner known to the art by first passing the webbing through both rings and then back over the periphery of one of the rings and throughthe other ring releasably 62 and 64 adjustably to connect

shoulder portions

40 and 42.

For adjustment of the jacket in the chest region which it will be appreciated need not be of very wide range, I secure one end of a length 68 of webbing to the inner edge of the chest portion 16. This length first passes through a length adjusting buckle 70 and through the ring of a slotted hook connector, around the center post of the buckle 70 and is there secured to itself to form a loop. Similarly, a length 74 of webbing has a loop at one end thereof which receives the center post of a buckle 76. Webbing 74 passes through the ring of a T-head connector 78 back through the buckle 76 and is then secured to the inner edge of chest portion 36. As is known in the art, the effective length of either of the

webbings

68 or 74 can be changed by varying the position of the

buckle

70 or 76 carrying the loop end of the respective webbing.

I form

respective tunnels

80 and 82 at vertically spaced locations in the waist portion 14 of the unit 12 by securing lengths of fabric to the unit by any suitable means such as by stitching 84.

Respective tunnels

86 and 88 extend laterally of the waist portion 34 of unit 32 at vertically spaced locations thereon. Stitching 90 secures tunnel-forming lengths of fabric to the unit 32. A lower right-hand length of webbing 92 has a free end 94. From the free end 94 webbing 92 passes through a first ring 98, then around a legof a second ring 96 and back through both

rings

96 and 98. From that point, webbing92 passes through tunnel 88 through ring 104 disposed between the back edges of the two

units

12 and 32 to a position adjacent the back edge of unit 32 at which it is secured to the unit 32 by stitching 106. A webbing length 102 has a loop at one end thereof which receives both

rings

96 and 98 and a loop at the other end which carries the T-head connector 100.

A lower left-hand length of webbing 108 has a loop at one end which receives a slotted hook connector. The loop is secured to the unit 12 adjacent the front edge thereof by stitching 110 merely to locate the connector 112 for easy access. From stitching 110 webbing 108 extends through tunnel 82 and through the D-ring 104 back to a location on unit 12 at which it is secured to the unit by means such as stitching 114.

The upper right-hand waist adjusting webbing 116 extends from a free end 118 through a ring 120 around a leg of ring 122 back through both

rings

120 and 122 through tunnel 86 around a leg of a ring 128 and back to a location on unit 32 at which it is secured in place by means such as stitching 130.

The upper left-hand waist adjusting webbing 132 has a loop at the front end thereof which receives a slotted hook connector 136 and which is secured to unit 12 adjacent the front edge thereof by stitching 134. From the connector 136 webbing 132 extends through tunnel 80 and around the other leg of ring 128 back to a location adjacent the back edge of unit 12 at which location it is secured to the unit by stitching 138. i may employ res'pective areas of

stitching

115 and 139 for securing the ends of

lengths

108 and 132 to the lengths themselves

adjacent stitching

114 and 138 to prevent twisting of the webbing.

Respective groups of spaced

loops

140 and 142 secured to theback edges of

rear shoulder portion

22 and 42 receive a lacing 144 for adjustably connecting the rear shoulder portions at the back of the jacket.

From the structure described it will be apparent that the

bodies

12 and 32 are not joined at any location by a permanent and non-adjustable connection. An initial adjustment is provided by lacing 144 and final adjustments can be made by the waist area strap means without shifting the positions of the bodies on the wearers person.

In use of my improved adjustable jacket, the lacing 144 is pulled to draw

loops

140 and 142 together to approximate size of the wearer and the ends are tied. Next, the

respective webbings

52 and 60 are engaged with the pairs of

rings

54 and 56 and 62 and 64. The jacket is now ready for donning.

After donning the jacket the user connects the respective T-heads 78, 124 and 100 with slotted

hooks

72, 136 and 112. Minor adjustments in the chest region can be made by sliding buckles and 76 along the

webbing lengths

68 and 70. It will readily be appreciated that for a given size the range of adjustment in the chest region need not be as great as that which is provided in the waist region.

Having made the chest adjustment, the wearer next adjusts the jacket in the waist region by drawing on the free ends 94 and 118. Considering, for example, the lower waist adjustment with the T-head in engagement with the slotted hook 112 as one pulls on the end 94 the front edges of the

respective units

12 and 32 are drawn together. Owing to the fact that strap 92 passes freely through tunnel 88 and through the ring 104, the rear edges of the two

units

12 and 32 are drawn together at the same time. The action of the upper waist adjustment achieved by pulling on end 118 operates in a similar manner. Thus, the jacket is drawn tightly into contact with the wearer's person without shifting the positions of the

units

12 and 32 on the wearers body. For the same reason, a relatively wide range of adjustment is possible without discomforting the wearer and without interfering with effective functioning of either the jacket or the wearer.

It will be seen that l have accomplished the objects of my invention. I have provided an adjustable buoyant jacket which overcomes the defects of adjustable buoyant jackets of the prior art. My jacket may be drawn closely about the wearer's person without shifting the positions of buoyant bodies. It is relatively comfortable in all adjusted positions. It affords a relatively wide range of adjustment while being comfortable and effective in all adjusted positions.

It will be understood that certain features and subcombinations are of utility and may be employed without reference to other features and subcombinations. This is contemplated by and is within the scope of my claims. It is further obvious that various changes may be made in details within the scope of my claims without departing from the spirit of my invention. It is, therefore, to be understood that my invention is not to be limited to the specific details shown and described.
