Protective ski transport bag
Abstract
A disposable bag formed of thin foldable material having a
central pocket for receiving a pair of ski poles and a pair of side
pockets for holding skis. In a preferred embodiment, at least one
of the opposing walls of the central pocket is provided with an
opening through which intermediate portions of the poles may be
gripped for carrying the entire bag and its contents in sling
fashion, using the poles to provide a handle and to distribute the
suspending force. The bag protects the skis during transport, as
when mounted on an automobile ski rack, may be folded when empty
and carried by the skier in a pocket until use is required and,
because of its inexpensive construction, may be discarded after it
has served its purpose.

I claim:
1. A protective ski transport bag formed of thin foldable sheet
material selected from the group consisting of plastic film and
paper, said bag having a pair of flat elongated walls joined
together along their longitudinal side edges and also sealed
together along a pair of longitudinal inner lines, said inner lines
being spaced apart to define a central pocket open at one end of
the bag for receiving a pair of ski poles, said inner lines also
being spaced from the longitudinal side edges of said bag to define
a pair of side pockets open at said one end of said bag for
receiving a pair of skis, each side pocket being adapted to receive
a single ski, said side pockets being substantially longer than the
skis receivable therein and all of said pockets being substantially
equal in length, said bag and its contents having handle means
formed by manually gripping intermediate portions of the poles to
hold said poles together within said central pocket and thereby
form a sling for suspending the side pockets and the skis therein
in balanced condition, said walls being permanently joined together
to close said pockets at the end of said bag opposite from said one
end.
2. The bag of claim 1 in which said bag is one of a series of
identical bags joined end-to-end and formed integrally from the
same sheet material, each bag being separable from the other bags
of said series along transverse tear lines disposed at the ends of
said bags and delimiting each bag from the others.
3. The structure of claim 2 in which each bag of said series is
sealed at one end along a transverse seal line disposed in close
proximity to each transverse tear line.
4. The structure of claim 3 in which said transverse tear lines and
said transverse seal lines are parallel with each other.
5. The structure of claim 3 in which said transverse tear line is
defined by a series of perforations.
6. The structure of claim 1 in which at least one wall defining
said central pocket is provided with an opening intermediate the
length of said bag through which intermediate portions of ski poles

Description
BACKGROUND
Ski bags of various types are known in the art, as illustrated by
the constructions shown in U.S. Pat. Nos. 2,180,686, 2,250,388,
3,336,961, and 2,118,875. Such bags are frequently padded and, in
general, provide adequate protection for the skis during storage or
when they are handled and transported by commercial carriers. For
the most part, conventional ski bags are really items of luggage;
they are sturdy items intended for repeated use and are relatively
bulky even when empty.
U.S. Pat. No. 3,225,987 discloses a frame for interconnecting a
pair of skis and a pair of poles in such a way that the entire
assembly may be mounted on a conventional automobile ski rack and,
when removed from the rack, may be hand-carried as a rigid unit.
While the frame members maintain the skis and poles in spaced
relation, thereby preventing scratching and other possible damage
occasioned by direct contact during transport (an advantage which
even cushioned ski bags seldom provide), the frame members
themselves are relatively bulky and must therefore be stored in
some fashion when the skis and poles are to be used.
SUMMARY
One aspect of this invention lies in the recognition that
conventional storage bags and ski-carrying devices fail to protect
skis, bindings, and poles in a common circumstance where such
protection would be particularly desirable, namely, when the skis
and poles are being transported on an automobile ski rack. During
such transport, the ski equipment is commonly exposed to road dirt
and salt water splashed from the road surface. The forceful impact
of water and particulate matter on the skis would be expected to
affect a wax finish and might even damage the permanent surface
finish of the skis and poles. Since the skis are fully exposed to
the elements during transport, dirt, salt and ice collecting in the
bindings must ordinarily be removed when the destination has been
reached if such bindings are to perform their safety release
function when put to use. Even when the bindings are so cleaned,
there is always the danger that permanent damage affecting their
operation will have occurred (and remain undetected until a failure
results) because of corrosion, abrasion, and jamming caused by such
exposure. Finally, conventional racks make no provision for holding
straps and buckles so that they do not slap against the roof or
rear deck of a moving car and while an experienced skier would be
expected to tie the straps to prevent them from flapping in the
airstream it is still possible, even probable, that the tied straps
will become loosened and contact the roof or deck, distracting the
occupants of the car and perhaps even damaging the finish of the
automobile.
Accordingly, it is a main object of this invention to provide a ski
transport bag which is especially suitable for use in protecting
skis, bindings, and poles during transport on the rack of an
automobile. Another object is to provide a bag which, despite the
thin flexible material from which it is formed, may be used as a
device for holding together a pair of skis and ski poles and for
hand-carrying all of such equipment to and from the ski area. In
that connection, it is a specific object to provide a transport bag
which not only protects the skis from abrasive contact with each
other and with the poles, but which also is so flexible and compact
that it may be folded and placed in the pocket of a parka or other
item of clothing until further use is required.
An additional aspect of the invention lies in providing a
protective ski carrying device which is relatively inexpensive to
manufacture and purchase, so inexpensive that if necessary or
desirable such carrier may be discarded after a single use or after
only limited use. It is contemplated that the ski-carrying bags
might be available to the dealer or purchaser in roll form, each
bag being one of a series and being separable from the others along
a perforated tear line.
A particularly significant feature of the invention lies in
providing a thin disposable protective bag which depends on its
contents for stiffness and rigidity and which utilizes the
stiffness and dimensions of ski poles to form a carrying handle for
the entire assembly. More specifically, the bag comprises a pair of
sheets of plastic, paper, or other suitable material joined
together along their longitudinal side edges and also sealed
together along a pair of spaced longitudinal inner lines. The inner
lines are spaced apart to define a central pocket for receiving a
pair of ski poles and are also spaced from the side edges to define
a pair of side pockets for receiving a pair of skis. Because of the
flexibility or pliability from which the bag is formed, a user may
readily grasp intermediate portions of the poles while they are
contained within the central pocket and thereby use the poles as a
handle, and as a stiffening frame or spine, for supporting the
ski-containing side pockets in sling fashion. In the best mode
presently contemplated for practicing the invention, the walls of
the central pocket are provided with a pair of aligned apertures
through which mid-portions of the poles may be directly gripped to
provide, in effect, a direct handle for suspending and carrying the
bag and its contents. A somewhat similar result may be achieved by
providing the central pocket with only a single wall opening and,
as already indicated, less effective results may be achieved by
eliminating the wall openings completely and by gripping the ski
poles with the material of the bag interposed between the user's
hand and the poles.
In the disclosed embodiment, each of the three pockets is
permanently sealed at one end. Preferably, the seal line is
disposed immediately adjacent a perforation line which separates
one bag from the next in a series of multiple bags. Thus, when use
or purchase is desired, a bag may be separated from the series by
tearing it away from the rest along the perforated separation line.
The opposite end of the bag is open for insertion and removal of
the ski equipment but the pockets at such opposite end would
normally be closed by suitable tie bands or other temporary closing
devices after the skis and poles are placed within their respective
compartments or pockets.
Other objects, features, and advantages of the invention will be
apparent from the drawings and detailed description.

DETAILED DESCRIPTION
In the embodiment illustrated in FIG. 1, the numeral 10 generally
designates a bag formed of thin flexible, water-resistant and
generally tough, durable material such as plastic. Polyethylene
film has been found particularly effective but other polyolefins
and other plastic materials such as polyvinylacetate,
polyvinylchloride, polyesters and polyurethanes may also be used.
Furthermore, paper and other cellulosic materials treated by
conventional techniques to make it water resistant is believed
suitable, and it is believed apparent that combinations or
laminates of various plastics and papers may also be highly
effective.
Bag 10 consists essentially of a pair of flat elongated walls 11
and 12 joined together along their longitudinal side edges 13 and
14, and sealed together along a pair of longitudinally extending
inner lines 15 and 16. It will be observed that the inner lines are
spaced apart to define a central pocket 17 and are also spaced from
the longitudinal side edges to define a pair of side pockets 18 and
19. The term "joined" as used herein is intended to refer to the
fact that walls 11 and 12 meet along the longitudinal zones or
edges 13 and 14, it being understood that if desired such walls may
be integrally formed and that the bag may be extruded in tubular
form.
Bag 10 may be one of a connected series integrally formed from the
same sheet material and separable along transverse perforation
lines 20. Thus, FIG. 1 depicts two such bags, 10 and 10', which
have not yet been separated from each other along tear line 20.
Since bags 10 and 10' are identical, and since they are part of a
multiplicity of bags joined in end-to-end series, only one such bag
will be described in detail herein.
Bag 10 is closed at one end by a transverse sealing line 21 which
is parallel with perforation line 20 and is disposed in close
proximity thereto. When bags 10 and 10' are separated from each
other along tear line 20, bag 10 will constitute a complete unit
with three pockets each open at one end and closed at the other. By
tearing the bags apart along line 20, the open ends of the pockets
of the next bag 10' in the series will be exposed.
Side pockets 18 and 19 are each large enough to receive a ski and
its bindings, the length of the pockets exceeding the length of the
skis so that the open ends may be closed by a suitable tie band 22
in the manner illustrated in FIG. 2. Other conventional closing
means such as string, wire or suitable clips may be used or, if
desired, and if there is a sufficient length of plastic material,
the bag itself may be tied into a knot at a point beyond the ends
of the skis.
FIG. 2 illustrates the bag and its contents supported in flat
condition (i.e., with each ski assuming the same position in
spaced-apart relation) on a conventional ski rack 23 mounted upon
the roof of an automobile 24. In FIG. 3 a somewhat different ski
rack, also conventional, is illustrated; however, the main
difference with regard to the present invention is that the bag has
been folded so that outer pockets 18 and 19 are in contiguous
relation and the skis 26 have their bottom surfaces in direct
opposition. FIG. 4 more clearly illustrates the relationship of the
parts when the bag is so folded. Since the material of the bag is
thin, any conventional rack capable of supporting skis in the
opposed relation generally represented in FIG. 3 will also be able
to support such skis when they are contained within a folded bag 10
as represented in FIGS. 3 and 4.
The position of ski poles 27 within central pocket 17 is indicated
in FIG. 4. Hand carrying of the bag and its contents is greatly
facilitated by the provision of a pair of aligned openings 28 (FIG.
1) in the walls of the central pocket intermediate the ends
thereof. The opening permits a user to grasp intermediate portions
of the poles directly through the openings and to suspend the
entire bag and its contents by the poles in the manner illustrated
in FIGS. 5 and 6.
If desired, only a single opening 28 may be provided in one of the
walls of the central pocket; such an arrangement has the
disadvantage of requiring the bag to be oriented so that the
opening is exposed to the user before the shafts of ski poles 27
may be directly gripped but it does have the possible advantage of
providing greater protection for the poles themselves during
transport of the equipment on an automobile ski rack. As indicated
in FIG. 7, less satisfactory results may be achieved by eliminating
openings 28 entirely; in that event, the intermediate portions of
the poles may still be gripped, the main difference being that a
layer of plastic or paper will be interposed between the user's
hand and the shafts of the poles. The interposed layer of material
will tend to make it more difficult to achieve a secure gripping
action. It will be observed that where at least one opening 28 is
provided and the poles are gripped through that opening, the
opening itself tends to limit the extent to which the bag may be
shifted relative to the user's hand, thereby providing additional
security against the possibility that the bag and its contents
might slip out of balance or might somehow be released accidentally
by the user.
While in the foregoing I have disclosed an embodiment of the
invention in considerable detail for purposes of illustration, it
will be understood by those skilled in the art that many of these
details may be varied without departing from the spirit and scope
of the invention.
