The invention relates to a bag/suitcase that can be used as a normal luggage or transformed into a skateboard and driven as a scooter while leaving the content in the suitcase.
Invention Solution
The invention deals with the problem of a traveler carrying luggage when moving around airports, train stations or elsewhere. The invention will help the traveler to move faster and with less effort.
The invention, from now on called “Skate trolley”, is a luggage that can be converted into a skateboard scooter. Skate-Trolley is built around an external frame made of carbon fiber, fiberglass, plastic, aluminum structure or any other material strong enough to hold a person weight.
To this structure all items and systems are connected, in order to make Skate trolley very light there is no internal frame, but the external frame itself acts as a structural frame. Skate trolley has a retractable Driving Stick that steers the front wheel, a retractable platform with wheels and a door so the inside of the suitcase can be accessed to store luggage. The traveler standing on the platform can ride the luggage rather than carry it. The traveler, using the combined effect of a scooter and of skateboard steering effect, can maneuver in a small spaces with a lot of obstacles such as those found in airports.
FIG. 1—Skate-Trolley seen from the side—the picture shows the driving stick (4) in the operational position and, in dotted lines, the closed position. The standing platform (5) can be seen in the operational position and in the closed position by dotted lines. The door (12) that opens the luggage is in the closed position. A drawing of a foot and of the hands in dotted lines shows the correct position to drive skate-trolley.
FIG. 2—Skate-Trolley seen from the back—the driving stick is in the operational position and the cavity area (13) where the front part of the foot can be placed while riding is visible. The rear wheels can be seen (8,9) connected to the pivoting axle (14).
FIG. 3—Skate-Trolley seen from the front—the driving stick is in the operational position and the dotted line shows the closed position. The front wheel can be seen (1) connected to the driving stick (2,4).
FIG. 4—Skate-Trolley seen from the top—with the standing platform (5) in the operational position.
FIG. 5—Skate-Trolley seen in 3D perspective—with the driving stick (4) and the standing platform (5) in the operational position.
FIG. 6—Skate-Trolley—with the driving stick and standing platform in the operational position ridden by user.
FIG. 7—Skate-Trolley—with the driving stick in the operational position and the standing platform in the closed position pushed by the user standing on all three wheels.
FIG. 8—Skate-Trolley—with the driving stick in the operational position and the standing platform in the closed position pulled by the user standing on all three wheels.
FIG. 9—Skate-Trolley—with the driving stick in the operational position and the standing platform in the closed position pulled by the user in a trolley manner standing on just the rear wheels.
FIG. 10—Skate-Trolley—with the driving stick in the operational position and the standing platform in the closed position standing by itself on all three wheels.
FIG. 11—Skate-Trolley—with both the driving stick and the standing platform in the closed position carried by the user from the handle.
FIG. 12—Skate-Trolley—with both the driving stick and the standing platform in the closed position ready to be stowed.
FIG. 13—The front driving mechanism of Skate-Trolley.
FIG. 14—The standing platform mechanism of Skate-Trolley.
FIG. 15—The steering effect of the rear wheels, in a settled position. Note the imaginary vertical axis (160) and imaginary axle axis (161).
FIG. 16—The steering effect of the rear wheels, in the tilting position. Note the imaginary vertical axis in a settled position (190), the same imaginary axis after a tilting effect (191), also note the imaginary axle axis in a settled position (195) and the resulting imaginary axle axis (193) consequence of a tilting effect.
A detailed description is presented through the explanation of the major parts of the skate-trolley.
The External Frame
The external frame (18) of the Skate Trolley is made of any resistant and light material strong enough to hold a person weight. The external frame has the shape of a box to optimize loading and storing space. To the external frame all the following objects are attached to.
The Driving Stick (
A tube (103, Tube1) made of light but resistant material (aluminum, carbon-fiber, plastic etc.) is attached to the front part of the external frame (104) at point (109). A second tube (102, Tube2) of the same material, slightly longer in size and of smaller diameter, is fitted inside this tube telescopically.
At both ends there are circular rollers (108,110) so that Tube2 can easily turn on its axis inside Tube1. At the bottom, underneath the roller, a fork (105) connects it to the front wheel (1,106). By steering this tube, the front wheel will steer.
Both rollers are blocked in place by a bolt (107,111) screwed on Tube2.
The driving stick (101, Tube3) shaped as a T, has a diameter slightly smaller of Tube2 (102), in such a way that it can be pulled telescopically in and out from it. A pin connected to a spring fitted inside the driving stick will lock it in the operational or closed position. The user will switch from one position to the other by pressing on the pin and unlocking it (not shown in the drawings).
The Standing Platform (
Two tubes (131) Tube4 and (136) Tube5 made of light but resistant material (aluminum, carbon-fiber, plastic etc.) are attached to the external frame (137) of Skate-Trolley at point (130).
The standing platform (133) is connected to a U shaped lightweight tube (132) Tube6.
This U tube is of smaller diameter of the Tube4 and Tube5 and it will telescopically shift in and out of them. The standing platform has a skateboard like wheel system (134) attached to it.
This rear wheel system has as pivoting axle (
The Door
The door has two hinges (17) and a locking system (16) allowing it to be opened and closed.
The Handle
Skate-Trolley has a handle (15) attached to the external frame (by means of bolts or rivets) it so it can be carried in a standard suitcase like manner.
Invention Key Facts
The two following points together make the invention unique and particularly effective in the field of the application.
The Special Turning Effect
To help the user move efficiently in limited spaces, the Skate Trolley takes advantage of the combined effect of scooter and skateboard steering mechanisms. In other words, the driving stick (4) directly steers the front wheel (1) and enables the driver to steer while standing on the platform in a scooter manner. The rear wheels (8,9) behave in a skateboard like manner; the rear wheels axle (14) can gain an angle with respect to the platform letting the baggage tilt in respect of the ground (
Skate Trolley has No Extra Scooter Frame
The Skate trolley is designed in such a way that there is no internal frame connecting the wheels, the driving stick and the standing platform. In other words, the external frame shell structure (18) itself represent the infrastructure of Skate-trolley, there is no need for a separate and heavy structure such as a scooter frame.
This is achieved by building an external frame (
This design solution is key for the invention; it allows the Skate-Trolley to be very light and at the same time maximizes the space for the luggage inside the baggage.
