The present invention relates to vest type flotation devices, such as a life jackets and swim assist vests, having means for holding the flotation device in a folded configuration for transport and storage.
Life jackets and swim assist vests are types of flotation device intended to keep the wearer on the surface of a body of water, either while swimming or after accidentally falling into the water from a water craft. Such vests typically are wrapped around the user's torso with the user's arms extending through arm openings and the two front portions fastened together with a vertically extending zipper and horizontally extending straps whose adjacent ends can be fastened together with a buckle or the like.
Such devices are bulky and occupy much space when not in use, such as during transportation or storage.
It is an object of the present invention to provide a flotation device such as a life jacket or swim assist vest with means that can be used to retain the flotation device in a folded configuration when not in use. By “folded configuration” is meant the configuration achieved when the device is folded substantially along its longitudinal center line with the right and left sides being brought towards each other and substantially into abutment
The type of flotation device to which the present invention pertains has right and left front portions, a rear portion, and right and left sides formed at the juncture of the rear portion and the right and left front portions, respectively.
In a first embodiment a transport and storage strap member is attached substantially at its outer end to one of the right and left sides.
The transport and storage strap member has a first portion of a first releasable locking member set attached thereto adjacent its inner end. A second portion of the first releasable locking member set is attached to that one of the right and left front portions of the device adjacent the side to which the transport and storage strap member is attached. The first and second portions of the first releasable locking member set are configured to lockingly engage to retain the transport and storage strap member substantially in contact with the front of the flotation device during use.
A second portion of a second releasable locking member set is attached to the right or left side of the device opposite the side to which the outer end of the transport and storage strap member is attached. The first and second portions of the second releasable locking member set are configured to lockingly engage when the transport and storage strap is disengaged from the second portion of the first locking member set, twisted approximately 180 degrees about its longitudinal axis, and stretched across the back of the flotation device after the flotation device has been placed in its folded configuration.
In a second embodiment, the strap member is replaced with first and second releasable locking member portions are located on opposite sides of the device.
In a third embodiment, the strap member is replaced with an elastic loop member which can be stretched around the folded flotation device to hold it in its folded configuration.
The vest type flotation device 10 includes right and left front portions 20 and 22, a back side 24, right and left arm openings 30 and 32, a collar portion 34, upper and lower right side horizontal waist straps 40 and 42, upper and lower left side horizontal waist straps 44 and 46, and leg straps 48 and 50 (only partially shown).
The right and left front portions 20 and 22 are attached to the back side 24 along right and left seams 26 and 28. The outer ends of upper and lower right side horizontal waist straps 40 and 42 are attached to the right side of the flotation device 10, preferably by being sewn into right seam 26. Similarly, the outer ends of upper and lower left side horizontal waist straps 44 and 46 are attached to the left side of the flotation device 10, preferably by being sewn into left seam 28.
The right and left front portions 20 and 22 can be removably attached together, such as by a zipper 23 or a hook and loop fastener (not shown).
The inner ends of upper and lower left side horizontal waist straps 44 and 46 have attachment means such as the female portions of releasable snap buckles 52 and 54 attached thereto. The inner portion of upper right side horizontal waist strap 40 is adjustably attached to the male portion of snap buckle 52, and the inner portion of lower right side horizontal waist strap 42 is adjustably attached to the male portion of snap buckle 54, all as well known in the snap buckle art.
Upper and lower right side horizontal waist straps 40 and 42 are adjustably held in place by a vertically disposed right support member 60 attached there over, and upper and lower left side horizontal waist straps 44 and 46 are held in place by a vertically disposed left support member 62 attached there over.
In a first embodiment the male portion 64 of a first button snap set is attached to left support member 62 at its intersection with upper left side horizontal waist strap 44.
A transport and storage strap 70 is attached at its outer end to the left side of life jacket 10, preferably by being sewn into left seam 28 joining the left front portion 22 and back side 24. The inner end of transportation and storage strap 70 has the female portion 66 of a first button snap set attached thereto, the female portion 66 of the first button snap set facing downwardly towards left front portion 22 and at a location that allows the female portion 66 to engage the male portion 64 without any substantial sagging or stretching of transportation and storage strap 70 .
During use of flotation device 10 the male and female portions 64 and 66 of the first button snap set are releasably engaged so that transport and storage strap 70 is restrained from dangling.
When it is desired to transport or store flotation device 10, the male and female portions 64 and 66 of the first button snap set are disengaged and transport and storage strap 70 is rotated approximately 360 degrees about its juncture with left seam 28 to the back side 24 of life jacket 10, as seen in
Transport and storage strap 70 has a length such that when the backsides of right and left seams 26 and 28 are substantially folded into contact the female portion 66 and the male portion 164 can be brought into alignment.
As shown in
It is preferred to fold the back side 24 of flotation device 10 rather than the front side (the front side being comprised of right and left front portions 20 and 22) for several reasons. One reason such a configuration is preferred is that the present invention is preferably used in association with a flotation device having a fin projecting from the back side thereof, such as, for example, shown in the present inventor's U.S. Design Pat. No. D 606,151. Another reason is that the front is thicker due to flotation inserts and straps with associated buckles. However, if the flotation device does not have a fin projecting from the rear thereof, the right and left front portions 20 and 22 could be folded towards each other and strap 70 stretched across the front side to bring button snap portions 66 and 164 into alignment without having to twist strap 70.
Although it is preferred to employ button snaps having a female portion 66 and male portions 64 and 164 to secure transport and storage strap 70 to flotation device 10, other releasable fastening members having mating male and female members could be employed, including snap buckles such as 52 and 54.

It will be obvious to those having skill in the art that many changes may be made to the details of the above-described embodiments of this invention without departing from the underlying principles thereof. The scope of the present invention should, therefore, be determined only by the following claims.
