- Wheeled suitcases with telescopic handles are now the norm. This allows the traveler to tilt the suitcase onto its rear wheels and pull the suitcase by the handle so that the traveler does not have to lift the suitcase. This may be acceptable for the light traveler; however, for travelers going on extended vacations with multiple baggages, the simple suitcase with wheels and a telescopic handle just is not enough.
- Travelers may try to stack additional baggage on top of the rolling suitcase.
- Some suitcases even come with support members that extend from the front to increase the surface area for stacking.
- the support members are weak and are limited in the amount of baggage that can be placed on them.
- the stacked baggage is often times unsteady, and when the traveler comes to a stop and needs to rest, resetting the baggage into the vertical position causes all the stacked baggage to fall off.
- the traveler may rent a cart at an airport, if available.
- the cart must be returned. Therefore, the rental of a cart can be costly, and is definitely inconvenient.
- the present invention relates to a suitcase and undercarriage attached underneath it that, when pulled out or pushed out either manually or automatically (i.e. deployed), provides sturdy space to carry extra luggage effortlessly.
- the wheels are all gathered under the suitcase base in a closed configuration.
- the wheels are positioned in a way that will not interfere with each other.
- the front of the cart maybe slightly elevated to better keep the luggage and items in place and secure.
- the telescopic bars when not in use will have a protective box under the suitcase.
- a handle may be deployable from the suitcase to facilitate pushing the suitcase.
- the handle In the closed configuration, the handle can be hidden or embedded into the surface of the suitcase.
- the handles In the deployed configuration, the handles may be slightly slanted so as to facilitate pushing the suitcase.
- a containment unit such as a pouch or a bag may be attached to the handle so that the traveler can put extra items, like a coat, laptop, camera, etc. inside the pouch to free their hands and shoulders from extra items.
- the containment unit is collapsible and when closed becomes flush with the suitcase.

- the handle 120 may be attached to the suitcase 100 in such a way so as to allow the user to push or pull the suitcase 100 along the floor on the undercarriage 102 .
- the handle 120 is movably attached to the suitcase 100 .
- the handle 120 can move or be adjusted so as to have multiple positions relative to the suitcase 100 .
- Most typical suitcases having wheels also have a telescoping handle 122 that extends directly and linearly upwards relative to the suitcase at rest to allow the height of the handle to be adjusted so that in the extended position the traveler must tilt the suitcase onto a pair of wheels 206 located at the back end of the suitcase in order to push or pull the suitcase with the handle.
- the handle 120 in the deployed configuration projects behind the suitcase 100 in its resting or natural state, with the handle angled upward.
- a resting state of the suitcase is a stable position of the suitcase when the user is not holding it.
- This positioning of the handle 120 makes it easier for the user to push the suitcase.
- the handle 120 may be telescopic and/or rotatable. This allows the handle 120 to move not only in a linear up and down direction to change the height or length of the handle 120 , but also in a rotatable forward and backward motion to position the handle 120 above the suitcase 100 or even behind the suitcase 100 when the suitcase 100 is in a resting position. In combination with the wheels 206 , 208 on the undercarriage 102 , this positioning of the handle 120 allows the suitcase to be pushed without requiring the suitcase 100 to be tilted.
- the handle 120 comprises a grip portion 124 and a frame portion 126 connected to the grip portion 124 .
- the frame portion 126 may be rotatably attached to the suitcase 100 , either on the sides or on the back.
- the frame portion 126 may be attached to the suitcase 100 via a hinge mechanism 128 to allow the handle 120 to have at least two configurations, the deployed configuration, and a stored or closed configuration.
- the handle 120 may be a telescoping handle 500 that telescopes or slides in and out of the side of the suitcase 100 , thereby eliminating any rotational movement without sacrificing the deployed and stored positions of the handle.
- the sides 108 , 110 of the suitcase 100 may have rails or tubes 502 into which the telescoping handle 500 can slide into and out of.
- the rails or tubes may be angled in such a manner that when the telescoping handle 500 is extended, its position is in a convenient location for the user to grasp.
- the front portion 504 of the rails or tubes 502 may be lower than the rear portion 506 of the rails or tubes 502 . This allows the telescoping handle 500 to extend in a rearward and upward direction.
- the rails or tubes 502 may be connected to vertical tubes 510 via reinforcement bars 132 for added stability.
- the handle 120 is positioned upwardly and behind the suitcase 100 as shown in FIG. 3 .
- This allows the suitcase 100 to be pushed like a shopping cart.
- the handle 120 may rotate upwardly and towards the front of the suitcase 100 so that the handle 120 lands on the top wall 112 of the suitcase 100 as shown in FIG. 1 .
- the handle 120 may rotate downwardly towards the bottom of the suitcase 100 so as to be stored onto the back 106 of the suitcase.
- the top 112 and/or back 106 of the suitcase 100 may comprise a groove 130 to receive the handle 120 in the stored configuration so that the handle 120 is flush with the suitcase 102 .
- This allows the handle 120 to be at least partially concealed. Although the handle 120 may still be visible, since it is flush with the surface of the suitcase 102 and not protruding out; therefore, it is less likely to be damaged when tossed about.
- the frame portion 126 of the handle 120 may be attached to the suitcase along a reinforcement bar 132 .
- Reinforcement bar 132 transfers the forces applied upon it by the user pushing the handle 120 towards other foundational portions of the suitcase 100 so as to improve the stability of the handle 120 and the suitcase 100 while being pushed.
- the suitcase 100 may comprise a vertically telescoping handle 122 .
- the vertical telescoping handle may be inserted into vertical tubes 510 encased in the rear wall 106 of the suitcase 100 .
- the reinforcement bars 132 may extend from the attachment point of the handle 120 towards the vertical tubes 510 either at right angles to the vertical tubes 510 or at an oblique angle.
- the suitcase 100 may have an automatic deployment means 100 to automatically cause the undercarriage 102 to deploy without having to pull it out manually from the front.
- an automatic deployment means may be the actuation of a deployment member, such as the handle 120 , a button, a lever, a cable, and the like, to cause the undercarriage 102 to deploy.
- the deployment of the handle 120 automatically causes deployment of the undercarriage 102 . This can be accomplished by connecting the handle 120 to the undercarriage 102 with a series of cables, pulleys, and/or levers to convert the rotational movement of the handle into translational movement of the undercarriage.
- a sheath cable may connect the hinge to the undercarriage via a pulley. Deployment of the handle 120 causes the hinge to rotate in a direction that allows the sheath cable to unwind. The increased length of the sheath cable is directed to the forward movement of the undercarriage via the pulley.
- a frame portion 126 of handle 120 may extend from the top of the suitcase to the bottom of the suitcase with the frame portion hingedly connected to the bottom of the suitcase.
- the handle 120 may telescopically extend upwards.
- a first pulley may be positioned at the top, rear corner of the suitcase, a second pulley, may be positioned at the bottom, rear corner of the suitcase, and a third pulley may be positioned at the bottom, front corner of the suitcase, all on the same side.
- a similar pulley arrangement can be arranged on the opposite side.
- a first cable attached to the upper end of the frame portion may be connected to the back end of the panels through these pulleys.
- a second cable may be attached to the back end of the panel through the second pulley.
- Deploying the handle causes the first cable to pull on the panels in the forward direction due to the third pulley. Closing the handle, causes the second cable to pull on the panels in the rearward direction due to the second pulley.
- Various other pulley systems can be utilized to make the movement of the panels dependent on the movement of the handles.
- a series of linked arms may be connected to the handle so as to push the sliding panel 624 in and out with the handle 120 .
- the handle 120 or the rear 106 of the suitcase 100 may be hingedly connected to a first pair of link arms 800 .
- Hinges 808 and 810 can allow the first pair of link arms 800 to move relative to the suitcase 100 .
- a second pair of link arms 802 is hingedly connected to the first pair of link arms 800 at the back end of the undercarriage 102 .
- the back end of the undercarriage 102 comprises two slots 812 into which the second pair of link arms 802 can be inserted.
- the second pair of link arms 802 our hingedly connected to a third pair of link arms 804 inside the undercarriage 102 .
- the third pair of link arms 804 have two opposite ends 803 , 805 .
- the first end 803 is fixed to the base, but allowed to swivel about a hinge 807 that is connected to the base 200 of the undercarriage 102 towards the back end on one side 608 .
- the second end 805 is slidably connected to the sliding panel 624 on the opposite side 606 of the sliding panel 624 .
- the second end 805 may be slidably connected to the sliding panel 624 through a slotted link arm 806 which is fixed to the sliding panel 624 .
- the sliding panel 624 may have slots to accommodate the second ends of the third link arms.
- the slot 809 of the slotted link 806 or sliding panel 624 is configured to extend from one side 606 of the base 200 towards the opposite side 608 and towards the rear 604 so as to form an oblique angle relative to the side 606 or 608 .
- a similar arrangement of the third pair of link arms and slotted link arms is created on the opposite side, such that the two link arms of the third pair of link arms 804 cross at approximately the midpoint.
- the portion of the first pair of link arms 800 connected to the handle 120 or the rear 106 of the suitcase also leans backward causing the opposite ends of the first pair of link arms 800 that are connected to the second pair of link arms 802 to move in a forward direction.
- This causes the second pair of link arms 802 to also move in a forward direction. Since the second pair of link arms 802 is connected in between the first and second ends 803 , 805 of the third pair of link arms 804 forward movement of the second pair of link arms 802 causes the second ends 805 of the third pair of link arms 804 to move towards the center of the sliding panel 624 since the first end 803 is fixed to the base 200 .
- the panels may be spring-loaded and locked in the stored configuration so that actuating a button, lever, cable, handle, and the like, releases the lock, allowing the spring to release and automatically eject the platforms into the open or deployed configuration.
- a standard gas shock, gas assist strut, spring, and the like may be attached to the base and the support means.
- one end of the gas strut may be attached to the base 200 , and the other end of the gas strut may be fixed to the sliding panel 624 .
- the gas shock 900 is biased a few degrees less than vertical. This will apply a force on the sliding panel 624 that will assist it in deploying when the sliding panel is unlatched.
- FIG. 9 shows the undercarriage in a deployed position with the gas shock 900 extended, keeping the sliding panel 624 in a fully extended position.
- enough force must be applied to overcome the spring force of the gas shock to move the sliding panel to a stored position.
- a bag or other type of containment unit 140 may be attached to the handle 120 in such a way that deployment of the handle 120 also causes deployment of the containment unit 140 , and concealing the handle 120 causes concealment of the containment unit 140 .
- the containment unit 140 provides an additional pocket or storage compartment to hold a variety of material that can be easily accessed.
- the containment unit 140 has an open end 142 into which personal effects can be deposited and a closed end 144 to contain the personal effects that were deposited into the open end.
- the perimeter 146 of the open end 142 may be attached to the handle 120 , such that the handle 120 also forms the open end 142 when in the deployed configuration. When the handle 120 is in the closed configuration, the remainder of the containment unit 140 may be tucked underneath the handle 120 and made flush against the rear or top wall of the suitcase.
- any of the handles 120 , 122 , 500 disclosed in this application can lock at various positions to vary the precise positioning of the handles 120 , 122 , 500 .
- Other standard types of locks are also known, such as using resistance.
- the rotational movement of the handle 120 can be locked at various angles relative to the suitcase 100 using similar mechanisms.
- Removal of the suitcase 100 allows the undercarriage to be used like a dolly, flatbed cart, shopping cart, and the like to carry other types of loads.
- the handle 120 would be connected directly to the undercarriage instead of through the suitcase.

Abstract
A luggage with a deployable, wheeled undercarriage and movable handles. The undercarriage has telescoping support members that can be deployed or opened to carry additional baggage and closed when not required. Wheels on the support members allow the luggage to be moved along the floor without having to tilt the luggage. This increases the stability and the amount of baggage that can be added. The handles in the deployed configuration extend behind the luggage to facilitate pushing the luggage. Deployment of the undercarriage can be manual or automatic with actuation of a deployment member, such as the handle itself.
Description
- This patent application claims the benefit of United States Provisional Patent Application No. 61/342,203, entitled “Wheeled Suitcase Cart with Telescopic Push Handle and Pouch” filed Apr. 12, 2010 which application is incorporated in its entirety here by this reference.
- This invention relates to suitcases or luggage with a deploying undercarriage.
- Travelers are always looking for efficient and easy ways for carrying their baggage. Many times people in airports are trying to pull at least two suitcases at a time, as well as a small carry-on bag, briefcase, laptop, purse, cameras, etc. In addition, parents have to manage their children who also may have their own luggage and toys.
- Wheeled suitcases with telescopic handles are now the norm. This allows the traveler to tilt the suitcase onto its rear wheels and pull the suitcase by the handle so that the traveler does not have to lift the suitcase. This may be acceptable for the light traveler; however, for travelers going on extended vacations with multiple baggages, the simple suitcase with wheels and a telescopic handle just is not enough.
- Travelers may try to stack additional baggage on top of the rolling suitcase. Some suitcases even come with support members that extend from the front to increase the surface area for stacking. However, the support members are weak and are limited in the amount of baggage that can be placed on them. In addition, the stacked baggage is often times unsteady, and when the traveler comes to a stop and needs to rest, resetting the baggage into the vertical position causes all the stacked baggage to fall off.
- In some instances, the traveler may rent a cart at an airport, if available. However, when the traveler is finished using the cart, the cart must be returned. Therefore, the rental of a cart can be costly, and is definitely inconvenient.
- For the foregoing reasons there is a need for a luggage that allows the traveler to carry multiple baggage easily and effectively.
- The present invention relates to a suitcase and undercarriage attached underneath it that, when pulled out or pushed out either manually or automatically (i.e. deployed), provides sturdy space to carry extra luggage effortlessly. When not in use, the wheels are all gathered under the suitcase base in a closed configuration. The wheels are positioned in a way that will not interfere with each other. The front of the cart maybe slightly elevated to better keep the luggage and items in place and secure. Also, the telescopic bars when not in use will have a protective box under the suitcase.
- A handle may be deployable from the suitcase to facilitate pushing the suitcase. In the closed configuration, the handle can be hidden or embedded into the surface of the suitcase. In the deployed configuration, the handles may be slightly slanted so as to facilitate pushing the suitcase.
- A containment unit such as a pouch or a bag may be attached to the handle so that the traveler can put extra items, like a coat, laptop, camera, etc. inside the pouch to free their hands and shoulders from extra items. The containment unit is collapsible and when closed becomes flush with the suitcase.
- The undercarriage is constructed of lightweight material and uses minimal parts so as not to add excess weight to the suitcase. However, due to the use of rails and additional wheels, the undercarriage, including its support members can receive loads much heavier than what can be carried on standard suitcases.

suitcase 100 can be a standard suitcase or luggage defined by afront wall 104, arear wall 106 opposite thefront wall 104, twosidewalls front wall 104 and therear wall 106, atop wall 112 adjacent to the front andrear walls sidewalls bottom wall 114 opposite thetop wall 112 and adjacent to front andrear walls sidewalls front wall 104,sidewalls top wall 112 can be opened to access the interior of thesuitcase 100. Thebottom 114 andrear walls 106 are typically the walls that are placed on support surfaces, such as floors, tables, beds, and the like, when the user is trying to access the inside compartment or for moving thesuitcase 100 along the floor. Thesuitcase 100 can be a softcover suitcase or a hardcover suitcase. - As shown in
FIG. 2 , theundercarriage 102 comprises abase 200, a support means 202, a deployment means 204 that allows the support means 202 to deploy out and away from thebase 200, and a plurality ofwheels 206 that allows the undercarriage to move. In the preferred embodiment, theentire undercarriage 200 is attached to thebottom wall 114 of thesuitcase 100 to maximize the concealment of theundercarriage 102 in the stored configuration. Having theentire undercarriage 102 attached to thebottom wall 114 of thesuitcase 100 also eliminates any hindrance or obstruction to accessing the interior of thesuitcase 100. This allows the user to access the interior of thesuitcase 100 quickly and easily at any time during travel without having to adjust the undercarriage configuration. - The
base 200 may be any rigid structure sufficient to support thesuitcase 100. For example, thebase 200 may be a flat plate, a plurality of crossbars, a frame, and the like. In the preferred embodiment, thebase 200 is a flat square or rectangular plate orpanel 600 as shown inFIG. 6 . For the purposes of convenience only, thebase 200 may be labeled as having afront 602, aback 604 opposite thefront 602, twosides front 602 andback 604, atop surface 610 and abottom surface 612. The support means 202 deploys from thefront 602 of thebase 200. - The deployment means 204 may be attached to the
bottom surface 612 of thebase panel 600. In some embodiments, anangled bar 614 may be attached to thebottom surface 612 of thebase panel 600 along theopposite sides front 602 to theback 604 for added stability. In such an embodiment, the deployment means 204 may be attached to theangled bars 614. In some embodiments, theangled bars 614 alone may serve as the base. A set ofwheels 206 may be attached towards theback end 604 of thebase panel 600. In the preferred embodiment, twowheels 206 are attached to theback end 604 of thebase panel 600, one at each corner. In some embodiments, thewheels 206 may be attached to thesuitcase 100. - Referring to
FIG. 6 , the deployment means 202 may comprise a series of rails that slide along each other in a telescopic manner A pair of fixedrails 620 may be affixed to thebottom surface 612 of thebase 200 along the sides. A pair of slidingrails 622 may be configured to slide along the fixed rails in a forward and backward direction relative to thebase 200. A slidingpanel 624 may be attached to the pair of slidingrails 622 so that the slidingpanel 624 can slide in and out from the base 200 with the sliding rails 622. - In some embodiments, to further increase the length of the extension, additional sliding rails and additional sliding panels may be used. For example, a second pair of sliding
rails 626 may be slidingly engaged with the first pair of slidingrails 622 so as to further extend the reach of the first slidingpanel 624. The second pair of slidingrails 626 may be attached to the first slidingpanel 624. The first slidingpanel 624 may be further attached to a second pair of fixedrails 628. A second slidingpanel 630 may be slidably coupled to the second pair of fixedrails 628 via a third pair of slidingrails 632 to further increase the surface area upon which baggage can be stored. - In the preferred embodiment, drawer rails or drawer slides may be used. Although typical telescoping action utilizing a series of concentric tubes can also be used, the rail system provides for better sliding action as well as strength and durability. In addition, the sliding rails may be substantially the same length as the panel they support. This further increases the support to the panel.
- The front portion of the
undercarriage 102 maybe slightly elevated to better keep the luggage and items in place and secure. - The undercarriage may be made from a variety of strong and rigid structures, such as metal, carbon fiber, plastic, wood, and the like, or any combination thereof. Preferably, the undercarriage is constructed so as to be lightweight to minimize the added weight to the suitcase.
- In some embodiments, to lighten the weight of the present invention, the support means 202 may be a frame comprising a plurality of crossbars as opposed to a solid panel. The crossbars may slide along a rail or may be telescoping. As shown in
FIG. 10 , to protect the crossbars in the closed configuration, the undercarriage may further comprise a protective cover 1000 that can slide onto the support means 202. The protective cover 1000 may be constructed from any type of rigid material, such as plastic, wood, metal, and the like. The protective cover 1000 is essentially a rectangular, box-like casing with an open end 1002 on one side. The protective cover 1000 may have a series of slots 1004 to accommodate the wheels when slid onto the support means 202. -
Wheels undercarriage 102 to allow thesuitcase 100 to be rolled across the floor with ease. Thewheels base 200 and the slidingpanels wheels 206 may be attached to thebase 200, one wheel at each rear corner of the base. A second pair ofwheels 208 may be attached to the front corners of thebase 200. Alternatively, the second pair ofwheels 208 may be attached to the slidingpanel 624. In embodiments comprising a second slidingpanel 630, the second pair ofwheels 208 may be attached to either the second slidingpanel 630 or the first slidingpanel 624. In some embodiments, to maximize stability, wheels may be placed in all of the above locations. In some embodiments,slots 634 may be required in the slidingpanels panels base 200, in the stored configuration without receiving interference from theother wheels - The wheels can be any type of wheels used to allow suitcases to roll across a flat surface. For example, the wheels may be caster wheels, rubber wheels, ball wheels, and the like. The wheels may further comprise a lock to prevent unwanted movement of the
suitcase 100. This also eliminates the use of feet used in existing suitcases to prevent unwanted movement of the suitcase. Due to the absence of these feet, however, the suitcase of the present invention can be rolled on its wheels without having to be tilted, making it more convenient when there is a lot of starting and stopping. - The
handle 120 may be attached to thesuitcase 100 in such a way so as to allow the user to push or pull thesuitcase 100 along the floor on theundercarriage 102. In the preferred embodiment, thehandle 120 is movably attached to thesuitcase 100. In other words, thehandle 120 can move or be adjusted so as to have multiple positions relative to thesuitcase 100. Most typical suitcases having wheels also have atelescoping handle 122 that extends directly and linearly upwards relative to the suitcase at rest to allow the height of the handle to be adjusted so that in the extended position the traveler must tilt the suitcase onto a pair ofwheels 206 located at the back end of the suitcase in order to push or pull the suitcase with the handle. - In the present invention, however, the
handle 120 in the deployed configuration projects behind thesuitcase 100 in its resting or natural state, with the handle angled upward. A resting state of the suitcase is a stable position of the suitcase when the user is not holding it. This positioning of thehandle 120 makes it easier for the user to push the suitcase. To accomplish the proper positioning of thehandle 120, thehandle 120 may be telescopic and/or rotatable. This allows thehandle 120 to move not only in a linear up and down direction to change the height or length of thehandle 120, but also in a rotatable forward and backward motion to position thehandle 120 above thesuitcase 100 or even behind thesuitcase 100 when thesuitcase 100 is in a resting position. In combination with thewheels undercarriage 102, this positioning of thehandle 120 allows the suitcase to be pushed without requiring thesuitcase 100 to be tilted. - In some embodiments, the
handle 120 comprises agrip portion 124 and aframe portion 126 connected to thegrip portion 124. Theframe portion 126 may be rotatably attached to thesuitcase 100, either on the sides or on the back. For example, theframe portion 126 may be attached to thesuitcase 100 via ahinge mechanism 128 to allow thehandle 120 to have at least two configurations, the deployed configuration, and a stored or closed configuration. - In some embodiments, the
handle 120 may be atelescoping handle 500 that telescopes or slides in and out of the side of thesuitcase 100, thereby eliminating any rotational movement without sacrificing the deployed and stored positions of the handle. For example, thesides suitcase 100 may have rails ortubes 502 into which thetelescoping handle 500 can slide into and out of. The rails or tubes may be angled in such a manner that when thetelescoping handle 500 is extended, its position is in a convenient location for the user to grasp. For example, thefront portion 504 of the rails ortubes 502 may be lower than therear portion 506 of the rails ortubes 502. This allows thetelescoping handle 500 to extend in a rearward and upward direction. The rails ortubes 502 may be connected tovertical tubes 510 via reinforcement bars 132 for added stability. - In the deployed configuration, the
handle 120 is positioned upwardly and behind thesuitcase 100 as shown inFIG. 3 . This allows thesuitcase 100 to be pushed like a shopping cart. In the stored configuration thehandle 120 may rotate upwardly and towards the front of thesuitcase 100 so that thehandle 120 lands on thetop wall 112 of thesuitcase 100 as shown inFIG. 1 . Alternatively, or additionally, thehandle 120 may rotate downwardly towards the bottom of thesuitcase 100 so as to be stored onto the back 106 of the suitcase. The top 112 and/or back 106 of thesuitcase 100 may comprise agroove 130 to receive thehandle 120 in the stored configuration so that thehandle 120 is flush with thesuitcase 102. This allows thehandle 120 to be at least partially concealed. Although thehandle 120 may still be visible, since it is flush with the surface of thesuitcase 102 and not protruding out; therefore, it is less likely to be damaged when tossed about. - In some embodiments, the
frame portion 126 of thehandle 120 may be attached to the suitcase along areinforcement bar 132.Reinforcement bar 132 transfers the forces applied upon it by the user pushing thehandle 120 towards other foundational portions of thesuitcase 100 so as to improve the stability of thehandle 120 and thesuitcase 100 while being pushed. For example, thesuitcase 100 may comprise a vertically telescopinghandle 122. The vertical telescoping handle may be inserted intovertical tubes 510 encased in therear wall 106 of thesuitcase 100. The reinforcement bars 132 may extend from the attachment point of thehandle 120 towards thevertical tubes 510 either at right angles to thevertical tubes 510 or at an oblique angle. - In some embodiments, the
suitcase 100 may have an automatic deployment means 100 to automatically cause theundercarriage 102 to deploy without having to pull it out manually from the front. For example, an automatic deployment means may be the actuation of a deployment member, such as thehandle 120, a button, a lever, a cable, and the like, to cause theundercarriage 102 to deploy. As one example, the deployment of thehandle 120 automatically causes deployment of theundercarriage 102. This can be accomplished by connecting thehandle 120 to theundercarriage 102 with a series of cables, pulleys, and/or levers to convert the rotational movement of the handle into translational movement of the undercarriage. For example, a sheath cable may connect the hinge to the undercarriage via a pulley. Deployment of thehandle 120 causes the hinge to rotate in a direction that allows the sheath cable to unwind. The increased length of the sheath cable is directed to the forward movement of the undercarriage via the pulley. - In another example, a
frame portion 126 ofhandle 120 may extend from the top of the suitcase to the bottom of the suitcase with the frame portion hingedly connected to the bottom of the suitcase. Thehandle 120 may telescopically extend upwards. A first pulley may be positioned at the top, rear corner of the suitcase, a second pulley, may be positioned at the bottom, rear corner of the suitcase, and a third pulley may be positioned at the bottom, front corner of the suitcase, all on the same side. A similar pulley arrangement can be arranged on the opposite side. A first cable attached to the upper end of the frame portion may be connected to the back end of the panels through these pulleys. A second cable may be attached to the back end of the panel through the second pulley. Deploying the handle causes the first cable to pull on the panels in the forward direction due to the third pulley. Closing the handle, causes the second cable to pull on the panels in the rearward direction due to the second pulley. Various other pulley systems can be utilized to make the movement of the panels dependent on the movement of the handles. - In some embodiments, a series of linked arms may be connected to the handle so as to push the sliding
panel 624 in and out with thehandle 120. For example, as shown inFIGS. 7-8B , thehandle 120 or the rear 106 of thesuitcase 100 may be hingedly connected to a first pair oflink arms 800.Hinges link arms 800 to move relative to thesuitcase 100. A second pair oflink arms 802 is hingedly connected to the first pair oflink arms 800 at the back end of theundercarriage 102. The back end of theundercarriage 102 comprises twoslots 812 into which the second pair oflink arms 802 can be inserted. The second pair oflink arms 802 our hingedly connected to a third pair oflink arms 804 inside theundercarriage 102. The third pair oflink arms 804 have twoopposite ends link arms 804, thefirst end 803 is fixed to the base, but allowed to swivel about a hinge 807 that is connected to thebase 200 of theundercarriage 102 towards the back end on oneside 608. Thesecond end 805 is slidably connected to the slidingpanel 624 on theopposite side 606 of the slidingpanel 624. Thesecond end 805 may be slidably connected to the slidingpanel 624 through a slottedlink arm 806 which is fixed to the slidingpanel 624. Alternatively, the slidingpanel 624 may have slots to accommodate the second ends of the third link arms. Theslot 809 of the slottedlink 806 or slidingpanel 624 is configured to extend from oneside 606 of the base 200 towards theopposite side 608 and towards the rear 604 so as to form an oblique angle relative to theside link arms 804 cross at approximately the midpoint. - In use, when the
handle 120 is deployed or pulled backward, the portion of the first pair oflink arms 800 connected to thehandle 120 or the rear 106 of the suitcase also leans backward causing the opposite ends of the first pair oflink arms 800 that are connected to the second pair oflink arms 802 to move in a forward direction. This causes the second pair oflink arms 802 to also move in a forward direction. Since the second pair oflink arms 802 is connected in between the first and second ends 803, 805 of the third pair oflink arms 804 forward movement of the second pair oflink arms 802 causes the second ends 805 of the third pair oflink arms 804 to move towards the center of the slidingpanel 624 since thefirst end 803 is fixed to thebase 200. Due to theangled slots 809, as the second ends 805 of the third pair oflink arms 804 move towards the center of the slidingpanel 624, the slidingpanel 624 is pushed forward and deployed. Closing thehandle 120 causes reverse movement of each of these parts resulting in the slidingpanel 624 closing underneath thesuitcase 100. - Although these mechanisms are shown on the external surface of the suitcase, they can easily be placed internally so as to reduce the chance of damage and so as to be more aesthetically pleasing.
- In some embodiments, the panels may be spring-loaded and locked in the stored configuration so that actuating a button, lever, cable, handle, and the like, releases the lock, allowing the spring to release and automatically eject the platforms into the open or deployed configuration. For example, to further assist in deployment of the undercarriage, a standard gas shock, gas assist strut, spring, and the like may be attached to the base and the support means. For example, one end of the gas strut may be attached to the
base 200, and the other end of the gas strut may be fixed to the slidingpanel 624. In the preferred embodiment, the gas shock 900 is biased a few degrees less than vertical. This will apply a force on the slidingpanel 624 that will assist it in deploying when the sliding panel is unlatched. -
FIG. 9 shows the undercarriage in a deployed position with the gas shock 900 extended, keeping the slidingpanel 624 in a fully extended position. In order to stow the slidingpanel 624, enough force must be applied to overcome the spring force of the gas shock to move the sliding panel to a stored position. - In some embodiments, a bag or other type of
containment unit 140 may be attached to thehandle 120 in such a way that deployment of thehandle 120 also causes deployment of thecontainment unit 140, and concealing thehandle 120 causes concealment of thecontainment unit 140. Thecontainment unit 140 provides an additional pocket or storage compartment to hold a variety of material that can be easily accessed. Thecontainment unit 140 has an open end 142 into which personal effects can be deposited and aclosed end 144 to contain the personal effects that were deposited into the open end. Theperimeter 146 of the open end 142 may be attached to thehandle 120, such that thehandle 120 also forms the open end 142 when in the deployed configuration. When thehandle 120 is in the closed configuration, the remainder of thecontainment unit 140 may be tucked underneath thehandle 120 and made flush against the rear or top wall of the suitcase. - Like any telescoping handle, any of the
handles handles handle 120 can be locked at various angles relative to thesuitcase 100 using similar mechanisms. - Removal of the
suitcase 100 allows the undercarriage to be used like a dolly, flatbed cart, shopping cart, and the like to carry other types of loads. In such an embodiment, thehandle 120 would be connected directly to the undercarriage instead of through the suitcase. - The foregoing description of the preferred embodiment of the invention has been presented for the purposes of illustration and description. It is not intended to be exhaustive or to limit the invention to the precise form disclosed. Many modifications and variations are possible in light of the above teaching. It is intended that the scope of the invention not be limited by this detailed description, but by the claims and the equivalents to the claims appended hereto.
