Description
FIELD OF INVENTION
[0001] Embodiments of the current invention relate to the
mechanical arts and are directed to devices employing retractable
handles.
BACKGROUND OF THE INVENTION
[0002] Retractable handles integrated into luggage are a part of
popular luggage designs, due in part to the way the handles and
telescopic support bars slide seamlessly into the luggage.
[0003] In crowded airports and other places, a table or work
station for placing a drink and or a book, magazine, laptop, or any
other material or device is desirable and attempts have been made
to build travel work stations that attach to luggage. However,
these attempts generally fall short in achieving a table that is
easy to deploy for use and retract for convenient storage. These
attempts further fall short in achieving a table that pivots upon a
permanent attachment to the telescopic support bars and is
completely hidden from view when stored.
[0004] For example, U.S. Pat. No. 6,471,019 discloses a variation
of a table that can be attached to a handle. However, among other
differences, the table does not hinge to the retractable handle nor
does the table retract inside the luggage.
[0005] U.S. Pat. Application No. 2008/0134946 discloses a simple
table for luggage, but requires the table to be fully detached in
order to store it.
[0006] U.S. Pat. Application No. 2010/0236884 discloses a table for
luggage, but it also requires the table to be fully detached in
order to store it.
[0007] A need exists for a table to fit seamlessly within luggage
just as common retractable handles with telescopic support bars
seamlessly fit into luggage. The rush of modern travel motivates a
need for a table and retractable handle to change from being
completely stored to being deployed in a minimum number of steps.
These steps should be seamless and easy, and achievable even if the
user's hands are full.
SUMMARY
[0008] The lack of access to tables in crowded airports and the
inconvenience of attaching existing tables and cup holders to
retractable luggage handles and storing in separate compartments is
solved by the present invention. The present invention is a luggage
apparatus and an apparatus for any device that employs a
retractable handle. The luggage apparatus has a table that may be
deployed from a retractable luggage handle by pushing the table,
and may be stored in the same luggage along with the retractable
handle system with another push on the table.
[0009] Deploying or retracting and storing the table may take only
one extra step from the means of deploying or retracting and
storing commonly used luggage handles. It is also possible to
deploy and/or retract the table with no additional steps or
requirements from the person pulling the luggage. With common
luggage handles, a button can be pushed to ready a retractable
handle for deployment or retraction and storage. The integrated
table can be deployed by pushing the button and lifting the handle
as is done with common luggage handles and allowing the table to
fall to a rest position that may be parallel to the ground when the
luggage is in an upright, resting position. In other embodiments,
the table may require a push from a person so that the table falls
to the desired position, which may be parallel or substantially
parallel to the ground. Similarly, the table can be retracted and
stored by pushing on the table so that it lifts until the top of
the table and the bottom of the table are substantially parallel to
the handle system. Then, as is done with common retractable luggage
handles, a user may push the button to allow the handle to be
retracted and then push the handle to store the table and the
support bars substantially inside the luggage. The support bars may
be telescopic, in that one fits inside another, which may fit
inside another, and so on so that there may be a plurality of
supports bars that can extend in length or retract so that all the
support bars occupy less volume, particularly volume that is
substantially horizontal. It is also possible to use the invention
with no extra steps from common retractable luggage handles. In a
simple form, the handle can be lifted and the table will
automatically fall out into the deployed position. In another form,
the button that engages or disengages the retractable handle on
common luggage can also retract or deploy the table, so that no
additional manual steps by the person using the luggage are
necessary to retract and deploy the table.
[0010] The summary is provided to introduce a selection of concepts
in a simplified form that are further described below in the
detailed description. This summary is not intended to identify key
features or essential features of the claimed subject matter, nor
is it intended to be used to limit the scope of the claimed subject
matter. Other aspects and advantages of the current invention will
be apparent from the following detailed description of the
embodiments and the accompanying drawing figures.
DEFINITIONS
[0011] "deployed plane" is the configuration wherein the plane of
the top and bottom surfaces of a table are at the desired angle
with respect to the ground for a desired use. For the purposes of
illustrating one example of a desired angle for deployment, see
FIG. 6. This angle can be adjusted according to the user's
application.
[0012] "retracted plane" is the configuration wherein the plane of
the top and bottom surfaces of a table are parallel or sufficiently
parallel to two bars that extend and support a handle and best seen
in FIG. 2a, 2b, or 2c. The planes must be sufficiently parallel so
that the table can retract into luggage.

placed upon clearly illustrating the principles of the invention.
Although most of the drawings show the table and handle system
integrated into luggage, the integrated table and handle can be
used on all types of luggage and other rolling items, such as
bar-b-que grills, coolers and other items that are pulled or pushed
by a retractable handle.
DETAILED DESCRIPTION
[0027] The following detailed description of the invention
references the accompanying drawings that illustrate specific
embodiments in which the invention can be practiced. The
embodiments are intended to describe aspects of the invention in
sufficient detail to enable those skilled in the art to practice
the invention. Other embodiments can be utilized and changes can be
made without departing from the scope of the current invention. The
following detailed description is, therefore, not to be taken in a
limiting sense. The scope of the current invention is defined only
by the claims, along with the full scope of equivalents to which
such claims are entitled. For example, all figures show a common
rectangular box type luggage with a retractable handle. However and
still as an example, this invention is appropriate for all types of
luggage and cases with retractable handles or retractable bars,
such as duffel bags with retractable handles and cases with
retractable handles as well as other items and systems using
retractable handles or retractable bars, such as but not limited to
coolers and bar-b-que grills.
[0028] In this description, references to "one embodiment", "an
embodiment", or "embodiments" mean that the feature or features
being referred to are included in at least one embodiment of the
technology. Separate references to "one embodiment", "an
embodiment", or "embodiments" in this description do not
necessarily refer to the same embodiment and are also not mutually
exclusive unless so stated and/or except as will be readily
apparent to those skilled in the art from the description. For
example, a feature, structure, act, etc. described in one
embodiment may also be included in other embodiments, but is not
necessarily included. Thus, the current technology can include a
variety of combinations and/or integrations of the embodiments
described herein.
[0029] A table 120 capable of deploying from inside a suitcase and
retracting back into a suitcase and is integrated into the
retractable handle 124 system often seen on rolling luggage is
shown on FIG. 1 and described herein. Among other uses, the table
120 is capable of supporting items, such as a drink cup or glass or
a reading device or book.
[0030] The table 120 is generally attached to the left bar 108 and
the right bar 118 that support the luggage handle 124, but the
table can swivel or pivot at the point or points where it connects
to the left bar 108 and the right bar 118. The table 120 can swivel
or pivot so that it is parallel with the plane created by the left
bar 108 and the right bar 118 (this is when the table is in the
"retracted plane" as defined above) and is then capable of sliding
into the luggage. The angle created by the table 120 and the plane
of the two bars can go beyond perpendicular, and although often
limited by luggage or the handle, the table 120 could rotate a full
three hundred sixty degrees depending upon the location of the
pivoting attachment and the size of the table 120. The table 120
also has another attachment point or points where it can attach to
the left bar 108 and the right bar 118 so that the table is
selectively held in the retracted plane. When the table 120 is in
the retracted plane, the table 120 can retract inside the luggage
along with the handle 124 when the handle is pushed towards the
luggage.
[0031] In FIG. 2a, the pivoting attachment is shown to consist of
two shafts extending from the table, a left shaft 102 and a right
shaft 112, fixed to the table 120 and protruding in opposite
directions. The shafts are generally rods, but can be bolts,
dowels, axles, pins, poles or any type of shaft of a reasonably
strong material. The shafts are generally cylindrical, but could
also be polygonal and are perpendicular to the left bar 108 and
right bar 118. The material could be the same material as the table
120 or a different material, such as a metal or polymer or ceramic
or fiberglass or any other material strong enough, light enough and
inexpensive enough to be employed as a table in this
application.
[0032] The left shaft 102 and the right shaft 112 fit into a hole
in the left bar 103 and a hole in the right bar 113 in FIG. 2a, but
extensions and sockets may be reversed such that the table
contained the sockets and the left bar 108 and the right bar 118
contained the extensions. In another embodiment, the left shaft 102
and the right shaft 112 may be flanged on each end, so that the
shafts can rotate freely with respect to both the table and the
left bar 108 and right bar 118. In another embodiment, one shaft
has one flange on each end that maintain connection to the left bar
108 and the right bar 118 and the shaft runs through a hole in the
table 120 allowing the table to pivot around the shaft. The flange
may be integral to the shaft or the flanges may be separate pieces,
like nuts on bolts.
[0033] FIG. 1 shows two extensions of table 120 that are not fixed
to the left bar 108 and the right bar 118. The left extension 104
and the right extension 114 are capable of connecting to the left
bar 108 and the right bar 118, however, and one means of connection
is a temporary connection by friction force. In one embodiment, the
left extension 104 and the right extension 114 are springs or
consist partially of springs so that the left extension 104 is held
in a socket 106 in the left bar and the right extension 114 is held
in a socket 116 on the right bar primarily by means of the friction
force of the spring acting upon the corresponding socket. In
another embodiment, the sockets 106 and 116 can be curved wells so
that the curvature creates an additional force to the friction that
holds the left extension 104 and right extension 114 in the
corresponding socket. In addition to other embodiments, this
embodiment could be reversed so that the sockets were on the table
and the extensions were on the bars that support the luggage
handle. In one embodiment, wherein the left extension 104 connects
into the socket 106 and the right extension 114 connects into the
socket 116, the table 120 is parallel to the plane of the left bar
108 and the right bar 118. In another embodiment, only one
extension, such as the left extension 104, and one socket, such as
the left socket 106, can be used to hold the table in the retracted
plane. In another embodiment, the right side can hold the force. In
still another embodiment, a plurality of extensions and sockets can
hold the table in the retracted plane.
[0034] In some embodiments, the width of the table 120 is limited
by the distance between the left bar 108 and the right bar 118. In
some embodiments, the length of the table is limited by the
distance between the handle 124 and the luggage 140. Additionally,
the space between the end of the table 120 that is furthest away
from the pivot point on the table and the handle 124 may be two to
four inches when the table is in the retracted plane.
[0035] In the FIG. 1 embodiment, the left bar 108 and the right bar
118 typically fit in at least one larger bar each so that the left
bar 108 and the right bar 118 can retract towards the bottom of the
luggage 128 and the bars retract as the handle retracts providing
the table 120 is in the retracted plane. Retracting the table is
often done by applying a force to the table to lift it into a
position so that the table 120 is in the retracted plane and then
depressing a button 126 for retracting the handle 124. FIG. 1 shows
a groove 122 that allows shaft 102 and extension 104 to slide into
the luggage. When the table is retracted into the luggage, it can
be covered by fabric 130 or some other cover.
[0036] FIG. 2A shows another embodiment of the table 120 that
embodies a drink holder 202 and groove 204. The groove 204 can also
be a convex bump so that it protrudes from the table. In some
embodiments, there are one or more grooves or bumps. Different
combinations of grooves and bumps are possible.
[0037] The left shaft 102 and the right shaft 112 may have an
expanded end like the top of a bolt or nail, or the extension may
connect to nuts such that the left shaft 102 cannot easily come out
of the left hole 103 and so that the right shaft 112 cannot easily
come out of the right hole 113. The expanded end may be any
configuration that prevents a shaft from being pulled out of a hole
in one direction. The expanded end does not need to be an integral
piece with respect to the shaft, but can instead be a separate
piece like a nut on a bolt.
[0038] The left extension 104 and the right extension 114 may be
buttons that are depressed only when an opposing force depresses
the button. The force of the button may come from a spring. In one
embodiment, the buttons are similar to the buttons that are
depressed to adjust the height of commonly used crutches. The left
extension 104 and the right extension 114 can fit snugly into the
left socket 106 and the right socket 104 respectively, so that a
force is needed to move the table 120 into and out of the retracted
plane. The force needed to push the table 120 out and into the
retracted plane is generally more than one pound of force, but less
than forty pounds of force. In one embodiment, wherein a strong
connection is ideal, the ideal force applied to the table 120 is
twenty to forty pounds of force. In another embodiment, wherein the
table can be supported in the retracted plane by a means other than
or in addition to the friction force exerted between the left
extension 104 and left socket 106 and the friction force exerted
between the right extension 114 and right socket 116, the ideal
force applied to the table 120 is greater than one pound but less
than ten pounds. In an embodiment where a mix of the two features
is desirable, the ideal force applied to the table 120 is greater
than five pounds of force but less than twenty-five pounds of
force. In another embodiment, the desirable force applied to move
the table out of the retracted position is between ten and fifty
pounds. In another embodiment, the force required is less than one
pound of force.
[0039] FIG. 2B shows that the left shaft 102 and left extension 104
may be fixed to the left bar 108 and the right shaft 112 and the
right extension 114 may be fixed to the right bar 118. The left
hole 103 and left socket 106 are then on the table 120, as are the
right hole 113 and right socket 116. The left shaft 102 and the
right shaft 104 may have expanded ends like the head of a nail or
bolt or and expanded head similar to a flange and including a
flange. The expanded end may be any configuration that prevents a
shaft from being pulled out of a hole in at least one direction.
The expanded end does not need to be an integral piece with respect
to the shaft although it can be integral, but the expanded end can
also be a separate piece like a nut on a bolt or a collar on a
shaft.
[0040] There may also be a plurality of grooves or depressions or
humps 204. The table 120 can be integrated into retractable handle
systems wherein the button 120 for activating the handle 124 is
located on the luggage as shown or in other places. The table 120
can be integrated into luggage that does not have a button for
activating the handle 124, but instead uses other means to activate
the retractable handle. The left shaft 102 and right shaft 112 can
be above or below the other extensions 104 and 114 do not pivot.
There can be a plurality of extensions that do not pivot on each
side that hold the table 120 in the retracted plane.
[0041] In the FIG. 2C embodiment, the extension, which provides the
pivoting means wherein the table attaches to the left bar 108 and
right bar 118, is a single shaft. The single shaft 102 runs through
the table 120 and fits loosely around the shaft 102 so that the
table 120 can pivot around the shaft 102. The shaft runs through at
least one side of the left bar 108 and at least one side of the
right bar 118. The shaft may have expanded ends that are configured
to prevent the expanded ends from passing through holes 103 and
113. If the shaft 102 runs through both sides of the left bar 108
and the right bar 118, then the expanded ends of the shaft 102 can
be accessed on the outside of the left bar 108 and the right bar
118.
[0042] In one embodiment expressed in FIG. 3A, supports 332 and 334
are attached to the luggage or the left sheath 302 and the right
sheath 312 so that the table 120, when retracted inside the
luggage, rests on or next to the supports 332 and 334. Among other
benefits, the supports prevent the force of a tightly packed
suitcase from creating a force (the force created by a person
pushing on the flap or cover of luggage) pushing toward the back of
the luggage 350 so that the table 120 falls out of the retracted
plane. In other embodiments, the supports are not needed because
the extensions 104 and 114 are held in the left groove 122 in FIG.
3A and the right groove 132 in FIG. 3B.
[0043] In FIG. 3C, the groove 122 in the sheath 302 is large enough
to allow the shaft of shaft 102 to pass. In one embodiment, the
groove 122 width is only 1%-5% larger than the diameter of the left
shaft 102 and the left extension 104, but the groove 122 width can
be less than 1% larger than the diameter of the shaft and the
extension. In another embodiment and wherein the table is in the
retracted plane and in the luggage, the left shaft 102 and the left
extension 104 make constant contact with the sheath 302, and more
specifically the part of the sheath that is on the side of groove
122 that is closer to the back 350 of the luggage.
[0044] FIG. 3D, the groove 132 in the sheath 312 is large enough to
allow the shaft of shaft 112 to pass and the ratio could be
unlimited. In one embodiment, the groove 132 width is only 1%-5%
larger than the diameter of the right shaft 112 and the right
extension 114, but the groove 132 width can be less than 1% larger
than the diameter of the right shaft 112 and the right extension
114. In another embodiment and when the table is in the retracted
position and in the luggage, the right shaft 112 and the right
extension 114 make constant contact with the sheath 312, and more
specifically the part of the sheath that is on the side of the
groove 132 that is closer to the back 350 of the luggage. The
smaller groove to shaft ratio allows the table to be firmly held in
the retracted plane while the table is retracted.
[0045] FIG. 4A illustrates a different embodiment of the sheath
that contains the left bar 108 and the right bar 118 when the
handle 124 and the table 120 are partially retracted. Sheath 402 is
a flat, hard material that covers the table 120 when the table is
retracted and stored in the luggage. The material of the sheath 402
can be a hard plastic or metal such as sheet metal. The sheath can
be in many configurations, including multiple pieces of plastic or
metal and mixes of the same. For example, the invention could use
any existing plastic or metal individual sheaths 302 and 312 with
the appropriate grooves 122 and 132, and then covered with a sheet
of thin metal with tabbed ends 402 as shown in FIG. 4B. In another
embodiment, the sheath is one piece and receives both the smaller
bars 108 and 118 as well as the table 120.
[0046] FIG. 5 shows an embodiment of supports that can be used to
prevent the table 120 from falling out of the retracted plane. FIG.
5 shows a plurality of supports 502, 504, 506, 508, and 510 that
would be on top of the table when the luggage is laid down such
that the left bar 108 and the right bar 118 are closest to the
ground and parallel to the ground. There can be more or less
supports as shown in FIG. 5. A fabric 130 may be pulled tightly and
fastened tightly over the supports and the retractable table
120.
[0047] FIG. 6 shows an embodiment and method for obtaining a
desired angle for the deployed table 120. Spacers 602 may attach to
the luggage and allow the table 120 to rest on the spacer 602. The
spacers 602 may come in multiple sizes to accommodate various
angles for table 120. The spacers may attach to the bag in any
means known in the art, such as Velcro or snap buttons, or the
spacers may rest freely on the bag. A more permanent manner for the
device to come to a desired angle is to modify the level of
extensions 102 and 112 on bar 108 and 118. FIG. 6 also shows a hump
604. A plurality of humps may be included.
