Definitions

  • Device for transporting objects such as suitcases and shopping trolleys
  • the invention relates to a device for transporting objects such as suitcases, shopping trolleys or the like, which is to be carried by hand.
  • the freewheeling rollers cannot be used on stairs, so that the previously known travel cases have to be carried up and down the stairs, provided that the stairs are not equipped with a conveyor belt, which is only found in exceptional cases.
  • the same problem occurs with shopping scooters or similar small transport devices that are carried by hand, such transport devices especially helping elderly or physically disabled people when shopping * to bring the purchased goods home with as little effort as possible.
  • the shopping trolley etc. is usually provided with two free-running wheels, which are attached under a frame or container that holds the objects to be transported. Such a shopping scooter is usually pulled behind it by its user on a bracket.
  • stairs often represent a major obstacle to transportation, especially since the shopping trolley does not inconsiderably increase the weight of the goods to be transported.
  • the problem of climbing stairs is therefore usually solved in conventional shopping scooters in such a way that the goods carried are removed from the shopping scooter and, for example, are carried up the stairs by means of a bag.
  • the shopping scooter can of course also be pulled up on its wheels step by step, which requires some skill and strength.
  • the present invention has for its object to provide a device of the type under consideration, which is easier for your user to carry, especially on stairs.
  • the invention provides that the suitcase, shopping trolley or a similar device to be carried by hand is provided with a crawler chassis which has at least one caterpillar belt, preferably two caterpillar belts arranged next to one another, and is electrically driven.
  • the caterpillar tracks (or the caterpillar track) can run over a large number of rollers, which has the advantage that the track tracks are particularly easy to grip when driving over the edges of the stairs.
  • the crawler belts each run over two deflecting rollers and in between over a support rail which, for example, reduces friction, e.g. can be coated with Teflon.
  • This design in turn has the advantage that the caterpillars drive almost without noise over the stair nosing, the grip can be increased in that the crawler belts are profiled on their outer sides or provided with knobs.
  • the driving force of the electric motor is preferably transmitted to one of the two deflection rollers, preferably a single crawler belt, from where the torque is transmitted from a connecting shaft to the opposite deflection roller of the other caterpillar belt.
  • a push button or rotary knob or a sensor is expediently arranged in the region of a handle of the device, it being preferred that the electric motor only run as long as the push button or sensor is actuated. This prevents the device from being inadvertently moved away from the crawler track.
  • the running direction of the crawler belts and the driving speed can be adjustable. If the device is a travel case, the crawler belts are arranged on the bottom of the case.
  • the caterpillar belts are preferably of such a length that they always rest on a staircase on at least two edges of the stair treads, so that the case automatically moves up or down the stairs when the button or sensor provided on the handle is actuated, the user only having to pay attention to this has that the suitcase does not get out of its direction of travel and does not collide with other people etc. as it moves.
  • the transport of the case is also facilitated on horizontal or inclined planes, especially when the surface has smaller or larger unevenness over which the caterpillar tracks can roll much more easily than free-running rollers.
  • the suitcase - unlike conventional travel suitcases - does not have to be pulled.
  • the caterpillar belts on the floor can in principle also be arranged on another circumferential wall, which then forms the underside of the suitcase when it is transported on a staircase.
  • one of the two side walls of the travel case can also be used.
  • the hitherto customary free-running rollers can then be located on the bottom of the case, on which the case can be pulled behind the user on a suitable transport route.
  • the caterpillar belts of the device according to the invention are preferably made of rubber and can be designed as toothed belts which run on appropriately designed rollers — either two deflection rollers or a multiplicity of rollers arranged closely next to one another.
  • the electric motor is preferably located in the travel case on the end region of the crawler belts facing away from the handle, which has the advantage that the section of the caterpillar belts lying below is tensioned tightly by the motor when driving up stairs.
  • the torque of the electric motor can be transferred to the drive roller via a planetary gear.
  • the connecting shaft between the drive roller of one caterpillar belt and the opposite roller of the other caterpillar belt consists of two parts which automatically engage with one another in a force-locking manner when the case is closed.
  • An ON / OFF switch can be provided to actuate the electric motor.
  • the electric motor is only in operation as long as the user actuates the associated switch, preferably a rocker switch or twist grip switch. It can be provided that the engine is switched off immediately when the user releases the actuation switch. The same effect can be triggered, for example, by a sensor button.
  • the bottom of the case is reinforced with ribs which, owing to their enlarged cross-sectional dimensions, are suitable for forming the bearing points for the axes of the rollers over which the endless belts run. If there are no support rails, but only rollers for the caterpillar belts, approximately 8 to 10 such rollers can each guide a caterpillar belt, a corresponding number of ribs being provided on the bottom part of the luggage item.
  • the bottom can be made as a separate plastic part that is connected to the other parts of the case.
  • the device according to the invention is a shopping trolley, which a user usually pulls behind him by means of a bracket in an inclined position on two wheels, there are in turn preferably two spaced-apart caterpillar tracks on the side of the shopping scooter, which in the normal transport position are inclined downwards points.
  • the side of the shopping scooter which, if the shopping scooter was pulled up a flight of stairs step by step, faces the front edges of the steps.
  • the shopping scooter according to the invention expediently has a frame, a frame or a continuous wall or similar component which is suitable for holding the crawler track, the associated electric motor with gear and the batteries, the latter components, of course, should be behind a closed cover , over which only the caterpillars protrude.
  • the shopping trolley or a similar small transport device to be carried by hand is brought into such an inclined position that the caterpillar belts rest against at least one leading edge of the stairs. It is not absolutely necessary for the crawler belts to be of such a length that they always lie against two leading edges of the stairs, since the user guides the shopping trolley by a handle while climbing the stairs, the inclination of the shopping trolley being able to vary somewhat.
  • a U-shaped handle can be pivotally attached to the frame etc. and provided with a bracket which can have several engagement positions for the frame for the handle adjustment.
  • the direction of travel of the caterpillar belts can also be reversible in the shopping trolley, and provision can also be made for the speed to be adjustable.
  • the shopping trolley With the shopping trolley according to the invention, a considerable load can be transported up the stairs in a convenient manner, practically without physical exertion, and this naturally also applies to the reverse direction. Since the shopping trolley can also be conveniently guided with its handle when climbing stairs, the crawler belts can be relatively short, i.e. you only have to bridge the gap between two stair noses.
