Abstract
A buoy which is suitable for supporting various sizes of beverage containers and allows the center of gravity of the combined buoy and container to be readily adjusted in order to restrain tipping.
Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to buoyant devices for supporting otherwise unfloatable objects on a liquid. In another aspect, the invention concerns a buoy for supporting a container in a generally upright position when the combined buoy and container are placed in water. In a further aspect, the invention concerns a buoy which is suitable for supporting various sizes of conventional beverage containers and allows the center of gravity of the combined buoy and container to be readily adjusted in order to restrain tipping.
2. Discussion of Prior Art
Persons who enjoy recreational water activities, such as swimming and fishing, frequently desire access to beverages while in the water. However, during such recreational activities, it is typically undesirable to continuously hold a beverage because the use of both hands may be necessary to fully enjoy the recreational activity.
To address this problem, a variety of conventional floating beverage holders have been developed which can support one or more beverage containers on the surface of the water. Existing floating beverage holders, however, present a number of drawbacks. For example, most conventional floating beverage holders will not accommodate beverage containers of various sizes (i.e., having varying outside diameters). This is particularly disadvantageous when a person desires to use a beverage insulator to keep their beverage hot or cold. Because the thickness of conventional beverage insulators can vary greatly depending on their specific material of construction, insulated beverage containers will frequently not be suitable for use with conventional floating beverage holders. Further, even if the conventional floating beverage holder is designed to accommodate insulated beverage containers, such beverage holders are typically not suited for accommodating uninsulated beverage containers.
A further disadvantage of existing floating beverage holders is their size. The bulkiness of these conventional devices make it undesirable and/or impractical to pack, transport, and store these devices. This disadvantage is especially pronounced when persons enjoy recreational water activities at locations requiring substantial travel. When packing a limited amount of supplies to travel to a remote recreation location, including a bulky conventional floating beverage holder may simply be impractical.
A still further disadvantage of conventional floating beverage holders is the fact that the beverage container must be removed and reinserted into the holder every time the user takes a drink. This removal/reinsertion action can be difficult in the water, and often requires the use of two hands to grasp both the holder and the beverage container. The use of two hands to remove and reinsert the beverage into the holder can make the use of conventional floating beverage holders impractical, especially when enjoying recreational activities requiring the use of two hands.
Another disadvantage of conventional floating beverage holders is the inability to adjust the center of gravity of the combined holder and beverage container. This inability to adjust the center of gravity can be particularly disadvantageous when tall beverage containers, such as some conventional water bottles, are supported by the floating beverage holder.
An additional disadvantage of conventional floating beverage holders is that they tend to float away from the individual, thus making it necessary for the individual to relocate towards the beverage holder in order to take a drink of the beverage.
SUMMARY OF INVENTION
Responsive to these and other problems, an important object of the present invention is to provide a floating beverage buoy suitable for use with a variety of sizes of containers.
A further object of the present invention is to provide a floatable beverage buoy having a compact shape (especially a minimal thickness) which allows it to be easily packed, transported, and stored.
A still further object of the present invention is to provide a floating beverage buoy having a compact shape and low weight which allows the buoy and the container to be readily manually manipulated as a single unit (i.e., a person can easily lift and consume liquids from the container without removing the container from the buoy).
Another object of the present invention is to provide a floating beverage buoy wherein the center of gravity of the combined buoy and beverage container can be readily manually adjusted in order to restrain tipping.
Still another object of the present invention is to provide a floating beverage buoy which prevents the buoy and beverage container from floating away from an individual user and provides a means by which the container can be retrieved if it has floated out of the reach of the individual user.
It should be noted that not all of the above-listed objects need be accomplished by the invention claimed herein and other objects and advantages of this invention will be apparent from the following description of the invention and appended claims.
In accordance with one embodiment of the present invention, a buoy for supporting any one of a variety of sizes of containers in a generally upright position when the buoy and supported container are placed in water is provided. The buoy generally comprises a buoyant body, a generally circular opening, and a resilient holding member. The opening extends through the body along an opening axis and is adapted to receive the container. The resilient holding member defines at least a portion of the opening and is adapted to frictionally engage the container when the container is received in the opening. The resilient holding member is sufficiently flexible to allow the diameter of the opening to be varied by at least 10 percent without causing substantial plastic deformation of the resilient holding member.
In accordance with another embodiment of the present invention, a buoy for supporting any one of a variety of sizes of containers in a generally upright position when the buoy and supportive container are placed in water is provided. The buoy comprises a body which presents an inner surface. The inner surface at least partially defines an opening extending through the body along an opening axis. The opening is adapted to receive the container. The inner surface presents a tapered portion. The tapered portion extends at a taper angle which is oblique relative to the opening axis when the container is not received in the opening. At least part of the tapered portion is elastically deformed by and frictionally engages the container when the container is received in the opening.
In accordance with a further embodiment of the present invention, a buoy for supporting any one of a variety of sizes of containers in a generally upright position when the buoy and supportive container are placed in water is provided. The buoy generally comprises a body presenting an outer perimeter and defining an opening extending through the body along an opening axis. The opening is adapted to receive the container. The body defines a plurality of spaced-apart, open slots extending between the opening and the outer perimeter. The open slots include an open end positioned adjacent the opening and a closed end positioned between the opening and the outer perimeter. The open slots allow the body to be sufficiently deformed so that the size of the opening can be varied to accommodate containers having various outer diameters without causing substantial plastic deformation of the body.

DETAILED DESCRIPTION
Referring initially to
FIGS. 1-3
, a floating beverage buoy
10
in accordance with one embodiment of the present invention is illustrated. Buoy
10
generally comprises a body
12
presenting an upper surface
14
, a lower surface
16
, an outer perimeter
18
, and an inner surface
20
.
Referring to
FIG. 2
, inner surface
20
defines an opening
22
which extends through body
12
along an opening axis
24
. Inner surface
20
includes a tapered portion
26
extending at a taper angle
27
which is oblique relative to opening axis
24
. Preferably, substantially all of inner surface
20
is tapered. Taper angle
27
of tapered portion
26
, measured relative to opening axis
24
, is preferably in the range of from about 15 degrees to about 75 degrees, more preferably in the range of from about 30 degrees to about 60 degrees, and most preferably in the range of from 40 degrees to 50 degrees.
As shown in
FIG. 2
, when a container
28
is received in opening
22
, at least a portion of tapered portion
26
(i.e., a deformed portion
29
) is elastically deformed by and frictionally engages the outer surface of container
28
. Body
12
of buoy
10
is preferably composed of a resilient material
30
which allows tapered portion
26
to be deformed when container
28
is received in opening
22
without causing substantial plastic deformation of tapered portion
26
. The shape of inner surface
20
provides opening
22
with a generally frustoconical shape having a wide portion of opening
22
proximate upper surface
14
and a narrow portion proximate lower surface
16
.
The configuration of inner surface
20
combined with the resilient properties of body
12
allows the diameter of opening
22
to be varied without causing substantial plastic deformation of body
12
. Preferably, the minimum diameter of opening
22
can be varied by more than 10 percent without causing substantial plastic deformation of body
12
, more preferably the minimum diameter of opening
22
can be varied by more than 20 percent without causing substantial plastic deformation of body
12
, still more preferably the minimum diameter of opening
22
can be varied by more than 35 percent without causing substantial plastic deformation of body
12
, and most preferably the minimum diameter of opening
22
can be varied by more than 50 percent without causing substantial plastic deformation of body
12
. Thus, opening
22
allows a variety of containers having outer diameters varying by more than 10, 20, 35 or even 50 percent to be accommodated by the same buoy
10
. Preferably, the minimum diameter of opening
22
is from about 1.5 to about 3.5 inches, more preferably from about 1.75 to about 3.25 inches, still more preferably from about 2.0 to about 3.0 inches, and most preferably from 2.25 to 2.75 inches. As used herein, the term “minimum diameter” of opening
22
shall mean the minimum distance measured on a straight line extending through opening axis
24
between opposing sides of inner surface
20
. In the embodiment shown in
FIG. 2
, such minimum diameter of opening
22
will occur proximate lower surface
16
of body
12
due to the tapered shape of inner surface
20
.
The frictional force imparted on the outside surface of container
28
by deformed portion
29
of inner surface
20
when container
28
is received in opening
22
is sufficient to at least substantially restrain shifting of container
28
relative to body
12
when container
28
and buoy
10
are placed in the water. The frictional engagement force between body
12
and container
28
should further be sufficient to restrain shifting of container
28
relative to body
12
when container
28
is grasped by an individual and lifted out of the water in order to consume a beverage from container
28
. However, the frictional engagement force between body
12
and container
28
should be small enough to readily permit manually-assisted shifting of container
28
relative to body
12
along opening axis
24
, to thereby allow the center of gravity of the combined buoy
10
and container
28
to be adjusted.
Buoy
10
preferably has a relatively compact, flattened shape. Thus, it is preferred for upper and lower surfaces
14
,
16
of body
12
to be substantially flat and to extend substantially perpendicular to opening axis
24
. The distance between upper and lower surfaces
14
,
16
is preferably minimized in order to provide a more compact buoy
10
. As such, the maximum body thickness of body
12
is preferably less than the minimum body width of body
12
. As used herein, the term “maximum body thickness” shall mean the maximum distance between any two portions (typically a point on upper surface
14
and a point on lower surface
16
) of body
12
measured along a line which is parallel to opening axis
24
. As used herein, the term “minimum body width” shall mean the minimum distance between any two points on outer perimeter
1
8
measured on a straight line extending through opening axis
24
. Preferably, the maximum body thickness of body
12
is less than one-half the minimum body width, more preferably the maximum body thickness is less than one-fourth the minimum body width. When buoy
10
is employed to support conventional beverage containers, the maximum body thickness is preferably less than about 2 inches, more preferably less than about 1.5 inches, still more preferably less than about 1 inch, and most preferably between 0.5 inches and 1 inch. Further, when buoy
10
is employed to support conventional beverage containers, the minimum body width is preferably more than about 4 inches, more preferably more than about 5 inches, still more preferably more than about 6 inches, and most preferably between 6 and 9 inches.
In order to achieve sufficient buoyancy to support container
28
in water, body
12
must be composed of a material having a relatively low density. Preferably, resilient material
30
of body
12
has a specific gravity of less than about 0.5, more preferably less than about 0.2, and most preferably less than 0.1. Resilient material
30
can be any material having the physical properties described above, such as, for example, a flexible foam material known in the art as Nitrile.
Referring to
FIG. 1
, buoy
10
can also be employed to support container
28
when container
28
is received in an insulator
32
. Further,
FIG. 1
shows that body
12
can include a hole
34
to which a tether
36
can be attached. A clip
38
can be coupled to the end of tether
36
opposite the end of tether
36
coupled to body
12
. Clip
38
can be any manually operable clip known in the art which can be readily secured to an anchoring device such as, for example, an article of clothing worn by the user of buoy
10
. Thus, tether
36
can prevent buoy
10
from floating out of the reach of the user. Further, tether
36
can be used to retrieve buoy
10
by simply pulling tether
36
towards the user.
Referring to
FIG. 4
, an alternate buoy
100
design is shown. Buoy
100
employs open slots
102
in a body
104
to provide for the expansion of an opening
106
necessary in order for buoy
100
to support a variety of containers having various outer diameters. Open slots
102
in body
104
include an open end
108
positioned adjacent opening
106
and a closed end
110
positioned between an inner surface
112
and an outer perimeter
114
. Open slots
102
extend generally radially outwards, relative to an opening axis
116
, from opening
106
into body
104
. Open slots
102
extend completely through body
104
in a direction which is at least substantially parallel to opening axis
116
. Inner surface
112
extends substantially parallel to opening axis
116
to thereby give opening
106
a generally cylindrical shape. A plurality of open slots
102
are preferably employed, more preferably at least 3 open slots are employed, and most preferably 4 open slots are employed.
When a container is forced into opening
106
, the diameter of opening
106
is increased due to elastic deformation of the portions of body
104
positioned adjacent opening
106
and generally between adjacent open slots
102
. Such deformed portions of body
104
can be deformed outwardly in a direction at least substantially perpendicular to opening axis
116
. Further, such deformed portions of body
104
can be deformed in a direction substantially parallel to the opening axis, to thereby expand opening
106
. Body
104
is formed of a material which allows body
104
to be deformed to hold various sizes of containers without causing substantial plastic deformation of body
104
.
The compact size, material of construction, and degree of opening adjustability of buoy
100
is preferably substantially the same as described above with reference to
FIGS. 1-3
.
The preferred forms of the invention described above are to be used as illustration only, and should not be utilized in a limiting sense in interpreting the scope of the present invention. Obvious modifications to the exemplary embodiments, as hereinabove set forth, could be readily made by those skilled in the art without departing from the spirit of the present invention.
The inventors hereby state their intent to rely on the doctrine of equivalence to determine and assess the reasonably fair scope of the present invention as pertains to any apparatus not materially departing from but outside the literal scope of the invention as set forth in the following claims.
