Abstract
The invention comprises generally square buoyant cushions. A separate fabric skirt is attached to each side of each cushion. Each skirt has fastening means so the skirts on one cushion can be fastened to the skirts on another cushion. If the cushions are stacked one on top of another, and the skirts of the stacked cushions are connected together, the skirts are sufficiently long so the buoyant compartment formed by the facing surfaces of the cushions and the connected skirts of the cushions will have sufficient volume for storing emergency supplies. In another configuration the skirts on the cushions can be connected together in side by side relationship to form a chain of buoyant cushions or a raft which can support a number of people so they will not drift apart in the water.

Description
This invention relates generally to buoyant life preserver cushions which can be connected together to form a chain of cushions or a buoyant compartment for storing emergency supplies, or which can be connected together to form a tote bag which can carry blankets and food and beverages and which can be reconnected in such a way that one cushion serves as a seat cushion and the other cushion serves as a cushioned back rest.
Prior Art and Background of Invention
Life preserver cushions have long been used in boats. Some as exemplified by the patent to Golding U.S. Pat. No. 65901 and Wood U.S. Pat. No. 264814 are designed to be connected together and can form a raft sufficient in size to support a number of persons and to carry emergency provisions.
Typically the life preserver cushions have a buoyant polyethelene foam core positioned inside a surrounding cover of water impervious material. When not used in an emergency situation they serve as cushions on the boat. The advantage of this use is that they are kept above deck so that in an emergency they can, as exemplified by the patents cited above, be connected together and thrown in the water where they can support a number of persons.
The advantage of using floatation cushions that can be connected together is that in an emergency situation the people in the water clinging to the connected cushions will stay together where they can help each other, and they will be more visible. Consequently, they can be more easily found be searchers, than a single person holding on to a single seat cushion.
However emergencies can happen very fast, and when a boat has to be abandoned there may be no time to gather emergency supplies.
There may be only enough time to abandon ship and cling to the cushions. Once in the water the persons clinging to the cushions may be able to connect the cushions together.
Summary of Invention
The present invention is a rectangular seat cushion designed to be used as a life preserver. The seat cushion is formed from a polyethelene foam pad encased in a water impervious fabric cover. In addition, the cushion is provided with a fabric border or skirt extending outwardly from all four sides of the pad. In this particular embodiment, male fasteners are located on two adjacent skirts of the pad, and female fasteners are located on the remaining adjacent skirts of the pad. The male and female fasteners are designed to be releasably interlocked with each other. In this way an unlimited number of seat cushions can be connected together to form a life raft or a chain of cushions.
In an alternate arrangement, two cushions can be stacked one on top of the other in such a way that the skirts of one cushion can be interlocked with the skirts of the other cushion to form a storage compartment defined by the facing surfaces of the cushions and the connected skirts of the cushions which form the walls of the compartment. This compartment would be filled with emergency supplies, prior to need. In this way if an emergency occured, the connected stacked cushions when thrown in the water would contain emergency supplies such as flares, a radio transmitter, and some food and water where it would serve as a flotation device and a floating container for emergency supplies.
In another use, cushions, which need not be buoyant, can be connected together to form a tote bag filled with a blanket and food and beverages. In this use, the tote bag would be carried, for example, to a football game, and the cushions separated in such a way that one cushion serves as seat cushion, and the other cushion serves as a cushioned back rest. Alternatively the cushions can be completely seperated so both serve as seat cushions while the blanket and supplies carried in the compartment are available for us.

FIG. 10 is an enlarged top plan view of the male and female fasteners shown in FIG. 9 in an unlocked condition.
FIG. 11 discloses another use of the cushions wherein a plurality of cushions are connected together to form an emergency stretcher or litter for carrying disabled persons.
Referring now to FIG. 1 of the drawing, a single floatation cushion indicated generally by the reference numeral 10a, comprises a generally planar surface 12a, side surfaces 14a, 16a, 18a, 20a, and a generally planar bottom surface 30a, see FIG. 1 and 4. As seen in FIG. 2, the cushion is generally square in shape and is constructed from a buoyant pad of polyethelene foam encased in a canvas cover. In the embodiment shown, the cushion is approximately fifteen inches on a side and three inches in thickness.
As shown in FIG. 2 four generally rectangular, fabric skirts 22a, 24a, 26a, and 28a, formed from a canvas like material extend out from each side of the cushion about two inches and in the same plane as the bottom surface 30a, see FIG. 4. As seen in FIG. 3, the length of the skirts connected to the edge of the bottom surface of the cushion are no longer than the length of the connected edge of the bottom surface of the cushion, and in this embodiment are substantially shorter. This permits the skirts to be bent individually without affecting the other skirts.
The skirts 26a and 28a at adjacent sides or corners of the cushion are provided, in this particular embodiment, with male fastening members 32, while skirts 22a and 24a at the opposite sides or corners of the cushion are provided with female fastening members 34. In this particular embodiment, each skirt is provided with three fastening members, either male or female although, under some circumstances a different number may be provided. In addition canvas straps 52 are attached to the bottom surface 30a extending, in this embodiment, from opposite sides of the cushion to provide hand holds or arm holds for a person in the water, see FIG. 2.
Each male fastening member 32 comprises an upstanding pedestal 36 which rises from a base 38. The base 38 is securely attached to a skirt by means of a pair of rivet connections 40. Each male fastener 32 has an elongated flat, narrow twistable head 42 which is rotatably mounted relative to the pedestal 36 by means of an integral vertical connecting post 44 which is rotatably mounted in the upper surface of the pedestal 36. see FIGS. 9 and 10. The twistable head seats in either of two perpendicular pairs of grooves or detent depressions 46 and 48 formed in the upper surface of the pedestal. With this arrangement the twistable head will tend to remain in one or the the other of the orthogonal positions. Moreover, this arrangement permits the head 42 to be twisted to the correct position in the dark, because when the head is rotated the person making the connection can feel when the head is aligned properly with the groove.
Each female fastening member 34 is a reinforced grommet or eyelet having an elongated opening 50 extending therethrough and having a length sufficient to accomodate insertion of the head 42 of the male fastening members 32 when the head 42 is aligned lengthwise with the opening 50 as illustrated in FIG. 10. When the head 42 is twisted perpendicular to the alignment with the opening 50, as depicted in FIG. 9, it is releasably locked to the female fastening member 34. In this position, the head 42 resides in registration with the detent depression 46b in the upper surface of the grommet 34.
The cushions are normally used as seat cushions in a boat. In the event the boat capsizes or sinks the cushions will bob to the surface and a person in the water can bring two of the cushions together and sequentially align each male fastening member on one skirt to a female fastening member on a skirt on another cusihon and then insert the head 42 of the male fastening member on one cushion into the opening 50 in the female member on another cushion. Then the head 42 would be twisted so it is at right angles to the opening. In this way, any number of cushions can be connected together to form a life raft or a chain of cushions, as illustrated in FIG. 11. By way of illustration, two cushions 10a and 10b are connected together see FIGS. 3 and 4 with the heads 42 on skirt 26b attached to cushion 10b inserted in the openings 50 in skirt 24a attached to cushion 10a to hold the cushions together.
As stated above, emergencies can happen very fast, as when a boat suddenly capsizes or sinks and there may be no time to gather emergency supplies. In anticipation of such an event, two cushions can be connected together, one on top of the other, to form a compartment for the storage of emergency supplies as shown in FIG. 5 and 6. In this configuration, the cushions are stacked so surface 30a on cushion 10a and surface 30b on cushion 10b face each other. The male fastening members on skirt 28b attached to cushion 10b are connected to the female fastening members on skirt 22a attached to cushion 10a. The male fastening members 26b attached to cushion 10b are connected to the female fastening members on skirt 24a attached to cushion 10a. The male fastening members on skirt 26a attached to cushion 10a are connected to the female fastening members on skirt 24b attached to cushion 10b, leaving skirts 22b attached to cushion 10b and skirts 28a attached to cushion 10a unconnected to serve as the opening for the insertion or the emergency supplies indicated in dotted lines in FIG. 5.
When all the emergency supplies have been stored, the male fastening members on skirt 28a attached to cushion 10a are connected to the female fastening members on skirt 22b attached to cushion 10b to hold the emergency supplies in the compartment defined by the facing surfaces 30a and 30b, and the walls of the compartment defined by the connected skirts as shown in FIG. 5 and 6. It is understood that the size of the containers holding the emergency supplies is larger than the openings at the corners of the compartment so that supplies stored in the compartment cannot fall out.
In this particular embodiment the cushions are about fifteen inches on each side and the skirts are about two inches long. Consequently the compartment formed by connecting the cushions as shown in FIGS. 5 and 6 would have a volume of about 450 cubic inches which is large enough to store flares, an emergency radio, a flashlight, and some high energy food. If required the size of the compartment could be varied by changing the size of the cushions or the length of the skirts.
When the cushions are stacked as shown in FIGS. 6 with the emergency supplies in the compartment described above, the cushions could still be used to sit on. But in an emergency as when the boat capsizes, the stacked cushions with the emergency supplies stored in the compartment would bob to the surface of the water where they could be used by persons in the water.
A land use of the cushions described above is contemplated. In this use two cushions are connected to form a combined tote bag and seat and back cushion as shown in FIGS. 7 and 7a. In this use, the cushions are connected together on three sides with the strap members fastened and assembled as shown in FIG. 7 positioned to be used as hand grips for the tote bag. A blanket and food and beverages may be carried in the compartment of the tote bag. If the tote bag formed this way were taken, for example, to a football game, the cushions would be separated to form a cushioned seat and cushioned back rest or two seperate cushioned seats and the blanket and other supplies, such as food and beverages would be conveniently available.
In addition, although the drawings disclose a pair of identical rectangular cushions, it is contemplated that the cushions could have shapes which are not rectangular and with pairs of cushions which are not identical. For example, the cushions could be circular having peripheral skirts which extend out beyond the periphery of the cushion far enough so they can be connected to the peripheral skirts on another cushion. Moreover although the skirts are described as formed from a fabric, other materials which are not fabric or flexible, are contemplated. For example the skirts could be formed from a rigid plastic connected to the periphery of the cushion by a narrow strip of fabric or by stitching or by glue.
It is also noted that the invention could be practiced using only one cushion. Referring to FIG. 5 it is evident that if cushion 10a were decreased in thickness until it was a thin sheet of fabric or a plastic like material, with the skirts 22a, 24a, 26a, and 28a, attached to it, the sheet 10a would become the cover of the compartment. In this way either an aquatic safety device or a tote bag having a storage compartment could be formed using one cushion and a cover.
