Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to an improved legging for animals such as
dogs.
There is a great need for a disposable protective covering for the
feet and legs of dogs in order to protect the feet and legs of the
animal from wet, dampness, dirt, chemicals, scratches, parasites,
parasite eggs, thorns, burrs, and the like. The unfilled need for
an inexpensive, convenient, and sanitary, disposable legging for a
dog is well known especially to those persons owning dogs which
must be kept indoors. Not only is there a need for such a legging
which will keep dirt, mud and moisture off the feet and legs of the
animal in order to eliminate the soiling of household floors, rugs
and furniture when the animal is brought indoors but, particularly
in urban areas, for such a legging to provide critical protection
for the soles of the animal's paws from salt and other chemicals
used on city streets in the winter. Salt or other chemicals which
may come in contact with minute cracks or scratches in the animal's
foot can be extremely painful as well as cause serious
infection.
A disposable protective legging for dogs which is inexpensive, can
be put on and taken off the animal quickly and conveniently, is
also greatly desired by dog owners exhibiting dogs in shows wherein
once the animal has been groomed, it is important, particularly in
the case of long-haired breeds, to protect the hair on the legs of
the animal from dirt and moisture.
Because of the inconvenience of cleaning soiled leggings for
animals after use, the availability of a very inexpensive
protective legging that could be disposed of after use is extremely
desirable. Another very important requirement for protective
leggings for dogs is that the legging should be designed so that
while providing the desired protection, it does not significantly
interfere with the natural gait of the animal. Such protective
legging should also be comfortable for the animal to wear and
should not be so tight as to cause discomfort or annoyance, or so
loose as to tend to easily fall off in use.
2. Prior Art
Protective leggings or boots for dogs have previously been
relatively complex devices which were difficult to place on the
animal's legs and made walking for the animal extremely awkward and
at times very discomforting. In many cases, the animal's normal
gait was completely disrupted by such legging. Because of the
particular materials and complexity of construction used in many
previous devices and the resulting expense, none of the prior art
leggings or boots could be considered truly disposable. Most
previous protective leggings were either stretched over the
animal's legs and constricted the legs tightly in order to keep the
leggings on, or adjustable binders required relatively involved
procedures to adjust them to the size of the individual dog. For
example, U.S. Pat. No. 2,446,371 Jones discloses a stretchable
galosh for dogs made of stretchable material which must be
stretched on to the animal's foot to fit snugly to prevent
dislodgement from the leg of the animal. Such devices, besides
being inconvenient to place on the animal's legs, are very
disruptive of the normal gait of the animal. Other galoshes of
complex sewn structure are disclosed in U.S. Pat. No. 2,443,831
Miller wherein the leggings are fastened to the leg of the animal
by elastic material bands which are sewn to the legging and secured
by fixed position snap fasteners. Such devices are essentially
non-adjustable and also in many cases will constrict the leg of the
animal to an extent to interrupt the normal gait.
SUMMARY OF THE INVENTION
The present invention provides a disposable protective legging for
a dog which is inexpensive, convenient to use, and which is
comfortable for the dog to wear and does not interfere with the
normal gait of the animal. The disposable protective legging of the
present invention is very simple in design and can be fabricated
very easily. The protective legging of this invention can be put on
and taken off the animal readily. The protective legging of this
invention is secured to the leg of the animal by means which can
easily be adjusted to accomodate the particular size of the
individual animal wearing the legging.
The disposable protective legging of this invention comprises an
upper leg portion, an intermediate leg portion, an ankle portion
and a paw portion. The legging is fabricated from two flexible
sheets of heat sealable thermoplastic material which are cut to
generally comform to the contours of the animal's legs. One sheet
comprises the back of the legging and the bottom part of the paw
section thereof and the second sheet comprises the front of the
legging and the top of the paw section thereof. The two sheets of
plastic are heat sealed together along the side and bottom margins
thereof, the top remaining open. The legging is provided with
adjustable means for gently but firmly securing it to the leg of
the animal. At least one of the securing means are located at the
ankle section of the legging and serves to gather the material of
the legging against the leg of the dog. The bottom of the foot
portion of the legging is provided with an anti-friction sole tread
which preferebly extends up the sides and front of the paw section
to serve as means to prevent wear and as additional protection for
the pad and toes of the animal.

DESCRIPTION OF SPECIFIC EMBODIMENTS
FIGS. 1 - 4 illustrate generally the basic structure of the legging
of this invention.
In FIGS. 1 and 3, there is shown a plastic disposable legging for
dogs according to this invention wherein the legging is
specifically configured for use on the rear leg of an animal. The
legging 2 comprises a generally tubular intermediate leg section 4,
a foot or paw section 6, and an upper leg section 8. As described
in greater detail below, the plastic legging is fabricated from two
sections of flexible plastic film such as polyethylene by merely
heat sealing two appropriately dimensioned sheets of plastic along
the outer margins thereof except at the top 10 thereof. The top is
not sealed in order to provide an opening for insertion of the
animal's leg. The bottom surface 14 of the paw section 6 of the
legging together with the front of the toe section 12 of the paw
section 6 is covered with a non-skid sole tread 16 as shown at 18.
The tread 16 may comprise a heavier gauge polyethylene plastic
which has a dimpled or otherwise scored roughened outer surface
which enhances the paw grip of the animal. The tread 16 can also
comprise other known non-slip composite materials which may be
adhesively secured to the surface 14 or preferably heat sealed
where appropriate for the material employed. An adjustable securing
means is shown schematically at 20 encircling the legging at
intermediate section 4 of the legging as shown. This securing band
serves to retain the legging on the leg of the animal by gently
gathering the plastic material against the leg of the animal at
that point. A corresponding legging particularly configured for the
front leg of the dog is illustrated in FIGS. 2 and 4 and except for
the configuration of the upper portion of the legs is substantially
the same as the embodiment of FIGS. 1 - 3. Thus, the disposable
front legging indicated generally at 22 comprises intermediate leg
section 24, a paw section 26 having toe portion 32 and bottom 34.
The tapered top of the legging is designed so that the uppermost
portion 28 extends partially up the chest of the animal to afford
greater protection. The bottom 34 likewise has a non-slip and
wear-enhancing tread 36 heat sealed or adhesively secured thereto,
and extending partway up the front of the toe section 32 as
indicated at 38. As before, two sheets of polyethylene film forming
the legging body are heat sealed at the margins except at the top
which is in this instance tapered as shown at 30 so as to fit
closely to the shoulder and chest of the dog.
In FIGS. 5 - 8, there is shown a preferred embodiment of the
disposable dog legging of the present invention. This embodiment is
designed for use on either the front and rear legs of the animal.
The legging of this embodiment is shown folded flat in FIGS. 5 - 7
and unfolded in FIG. 8. In this embodiment, the disposable legging
is indicated generally at 42 and comprises intermediate section 48
connected to the foot portion 52 by a slightly necked-in ankle
portion 47. The top 50 as in previous cases in open. As best shown
in FIG. 6, the legging is fabricated from two sheets of flexible 6
mil polyethylene material, a back 43 and a front 45, which are heat
sealed together along the side and bottom margins. The bottom 54 of
the paw portion 46 has an anti-wear and non-slip dimpled
polyethylene tread 56 heat sealed thereto. Tabs 57 overlap the
sides and toe portion 52 of the foot 46. A band 60 encircles the
legging above the necked-in ankle portion 47. The ends of the band
60 are provided with knobbed posts 64 and 66. An elastic band or
loop 64 is fitted over the knob 62 and fits over the knob 66 to
gather the legging firmly against the leg of the animal. The length
of the loop 64 is selected according to the size dog involved. FIG.
8 shows the legging of this embodiment unfolded as it would be with
an animal's leg placed therein.
The embodiment of the disposable legging of this invention which is
most particularly preferred is shown in FIGS. 9 - 11. The legging
itself is in all respects the same as the legging of FIGS. 5 - 8,
except that different means are provided for securing the legging
to the leg of the animal. The band and loop arrangement of the
previous embodiment which is somewhat expensive to manufacture is
replaced by two pairs of adhesive strips which gather the plastic
material to the configuration of the leg of the animal.
Referring to the drawing, the disposable legging is indicated
generally at 42 and comprises upper leg section 48, which is joined
to the foot section 42 by the necked-in ankle section 47. The
legging is open at the top 50. The bottom 54 of the foot section 46
has the non-wear or non-slip tread 56 secured thereto and to the
sides and toe section 52 by heat-sealing or is adhesively secured.
The tabs 57 of the tread 56 extend up the sides and front of the
foot section 46 as shown. An upper pair 68 and a lower pair 70 of
adhesive tabs are provided for gathering the legging material
together after the animal's leg is placed in the disposable
legging. The upper tabs 68 have a backing strip 74 on the face
thereof which is covered with an adhesive layer, and a removeable
paperlike cover 72 which when the legging is not in use covers the
adhesive face of the strip 74. In FIG. 10, the protective strip 72
is shown partially peeled back from the adhesive on the backing
strip 74. In a like manner, the tabs 70 are provided with
removeable protective covering 76 for the adhesive coating on the
backing strip 78. The inner ends of the tabs 68 and 70 are also
preferably heat sealed to the plastic material of the legging
itself and conveniently may be placed between the sheets at the
margins and sealed thereto in the same operation that joins the
sheets together.
As illustrated in FIG. 11, once the legging is placed upon the leg
of the animal, the protective covers 72 and 76 respectively are
removed from the tabs 68 and 70 and the tabs 68 and 70 are gently
pulled to gather the plastic material of the legging snugly around
the leg of the animal and then the adhesive coating is pressed
against the gathered plastic in order to secure the legging around
the leg of the animal firmly but gently. This embodiment of the
invention is particularly convenient to use and assures that the
legging will be securely maintained on the leg of the animal but
permits close adjustment to the individual animal.
The use of the adhesive tabs as means of securing the legging to
the leg of the animal is very inexpensive and furthermore takes up
less space than the post and loop arrangement of the previous
embodiment. In addition, the degree of tightness with which the
legging is gathered about the leg of the animal can be carefully
controlled by the dog owner using such adhesive tabs whereas in the
previous embodiments, the degree of tension is fixed and cannot be
adjusted to the thickness of the leg of each animal. For these
reasons, the present embodiment is particularly preferred.
It is apparent that any of the common flexible plastic materials
may be utilized in the practice of this invention. I have found
that polyethylene sheeting is particularly suitable. The thickness
of the material can be adjusted according to the degree of
durability that is desired for the disposable legging. I have found
that 6 mil thick polyethylene material is most suitable although
thicknesses of 2 to 10 mil are all very useful. A somewhat thicker
stock may be used for the anti-wear non-skid tread if desired.
While the invention has been explained by a detailed description of
certain specific embodiments, it is understood that various
modifications and substitutions can be made in any of them within
the scope of the appended claims which are intended also to include
equivalents of such embodiments.
