Definitions

  • the invention relates to a shopping scooter for transporting loads such as e.g. a beverage crate or groceries that can be in a bag or, for example, a box.
  • loads such as e.g. a beverage crate or groceries that can be in a bag or, for example, a box.
  • the shopping trolley has a base frame, on which preferably two free-running wheels and a crawler track are attached with at least one, preferably two crawler belts, which are driven by an electric motor, as long as an actuating device, for example an actuating button, is held in the ON position.
  • an actuating device for example an actuating button
  • the lower strand of the caterpillar tracks in the working position of the shopping roller protrudes beyond the underside of the base frame, so that the shopping roller can go up and down stairs on these caterpillar tracks.
  • the shopping trolley is held on the handle of a guide device which is connected to the base frame. With this handle, the shopping scooter is pulled on level routes such as a sidewalk, rolling on the wheels without the caterpillar belts touching the ground.
  • the load is usually both on the top of the base frame and on one in it lower area predominantly angled by 90o, although a hook can of course also be provided on the base frame, for example, on which a shopping bag can be suspended so that it does not touch this angled stop. If it is not required, the angled stop can also be foldable in contact with the top of the base frame.
  • the present invention has for its object to provide a shopping trolley that can be easily carried by an operator.
  • the invention provides that the guide device of the shopping scooter, with which it is pulled over essentially flat distances and held when climbing stairs, is adjustable in both directions beyond the level of the base frame.
  • the guide device can also be adjusted on the other side beyond the level of the base frame, the shopping trolley can then be pulled almost in a vertical orientation when it is pulled on flat routes, so that the transported load is essentially completely absorbed by the wheels becomes.
  • the angular position of the guide device can be adjusted downwards beyond the level of the base frame to such an extent that, depending on the load, such a position of the shopping scooter or such an angle between the contact surface of the base frame and the horizontal can be adjusted with a comfortable posture of the person pulling the shopping scooter that the shopping scooter moves on its wheels essentially in all-round equilibrium, that is to say that practically no supporting forces have to be exerted by the operator.
  • the adjustment angle beyond the underside of the base frame is approximately up to 45 °, but this depends, among other things, on the geometry of the shopping scooter.
  • the guide device is preferably pivotable to such an extent that it can be placed on the top of the base frame, in which case, of course, it does not transport any loads, but can be kept in a small space or can be carried in a motor vehicle, for example .
  • An angle of 60 ° to 70 ° should be appropriate as the maximum use position when climbing stairs.
  • the angular position of the guide device can be adjusted in stages, a small division being expedient so that each person can set the most convenient angular position for their body size and posture. For example, the angular position can be adjusted in steps of 5 °.
  • This adjustability is preferably made possible by a pawl mechanism in which a pawl is moved into the release position and the desired pivoting process is then carried out, whereupon the pawl locks the set position.
  • a pawl mechanism in which a pawl is moved into the release position and the desired pivoting process is then carried out, whereupon the pawl locks the set position.
  • other adjustment mechanisms can also be considered.
  • the guide device contains a tube which is connected centrally to the base frame in the width direction.
  • this tube can be connected in an articulated manner to a further tube, which is fastened to the base frame, essentially in its plane, via the latch mechanism mentioned above.
  • the tube protruding centrally in the width direction of the shopping scooter above the base frame makes it possible to pull the shopping scooter behind it more comfortably than a guide device which is as wide as the base frame of the shopping scooter. This also makes it easier to hold the shopping scooter while climbing stairs.
  • a further proposal of the invention contributes to this convenience, according to which the handle arranged at the free end of the tube should have an arc shape which extends in the longitudinal direction of the tube and is attached to the tube with both ends.
  • This handle runs in the plane in which the tube can be pivoted.
  • the handle expediently has a shape such that it connects to the tube on both sides at an angle of 60 °, the intermediate region having an arc shape.
  • the tube is expediently formed in one piece with the plastic handle.
  • the base frame is preferably made of plastic.
  • buttons or the like are provided as the actuating device for the electric motor, which only drives the caterpillar tracks when the actuating device is held in the ON position, one of which is provided is depressed to drive the crawler belts.
  • These actuators hereinafter referred to as actuation buttons, are arranged on the handle at such a distance from one another that when climbing stairs a finger (preferably the thumb) of the operator can lie comfortably on one actuation button and press it down, while when grasping down stairs the thumb of the operator Operator lies comfortably on the other operating button.
  • the operating buttons are automatically assigned a running direction of the crawler belts.
  • the spatially separate arrangement of two actuators constitutes an independent invention, which can also be used to great advantage if the guide device of the shopping scooter cannot be pivoted in both directions beyond the level of the base frame, and if the handle is one has a different shape.
  • the location of the two actuation buttons By a suitable choice of the location of the two actuation buttons, the possibility can also be created for left-handers to operate the device in the same comfortable posture as a right-hander.
  • the guide device is a telescopic tube, so that each person can adjust the length of the tube that is optimal for them.
  • All suitable mechanisms for adjusting and then fixing the length of the telescopic tube can be considered, for example a spring-loaded push button which can snap into one of a plurality of spaced-apart holes in the outer tube. Since the actuating buttons on the handle are electrically connected to the electric motor arranged in the base frame or its accumulators, it is proposed that electrical sliding contacts are arranged in the telescopic tube, which maintain the electrical contact at any set length of the telescopic tube.
  • the invention thus provides a shopping scooter that can be comfortably pulled along flat routes as well as being held when motorized stair climbing.
  • flat route is to be understood as a step-free route, which of course contains the usual bumps, for example a walkway, and can be inclined.
  • switching scooter denotes an area for which the cargo caddy is typically suitable, although other loads that do not originate from a purchase can of course also be transported outside the household area with it.
  • Figure 1 is a plan view of the base frame of a shopping scooter.
  • Figure 2 is a side view of the base frame with the handle of the device.
  • Fig. 3 a shopping scooter when climbing stairs
  • Fig. 4 shows the shopping trolley in an upright position.
  • the figures show a shopping trolley 1, which carries 2 caterpillar tracks 3 on a base frame, the lower strand of which rests on the stair nosing when climbing stairs.
  • two free-running wheels 4 are fastened to the base frame, on which the shopping trolley rolls when it is pulled on a handle 5 which is integrally formed on a guide tube 6.
  • a load (not shown) lies partially on the top 8 of the base frame and on the top 9 one of two stops 10 angled approximately at right angles from the base frame 2.
  • a support device 11 is also connected to the frame 2 and extends in the direction of the front of the shopping scooter 1 so that it can stand automatically on the wheels 4 and this support device 11 in a vertical position.
  • the base frame 2 contains a receiving space for the electronics 12 and the motor / gear arrangement 13.
  • a tube 14 extends from this housing part along the central longitudinal axis 15 of the shopping scooter 1.
  • the tube 15 is connected via a joint mechanism 16 to the guide tube 6, on which the handle 5 is integrally formed on the free end.
  • the articulated mechanism 16 has a pawl 17, upon release of which the guide tube 6 can be adjusted in stages between the two end positions shown in dashed lines in FIG. 2. The desired position is fixed by the pawl 17.
  • the shopping trolley 1 can be pulled in only slightly with respect to the pulling person inclined forward, ie almost vertical position, which makes it possible, with a corresponding load on the shopping trolley, in a comfortable, upright position
  • the exact angular position depends on the geometry of the shopping scooter 1, on the size and position of the load, but also on the size and posture of the person pulling. In the position of the guide tube 6 shown in dashed lines, this is pivoted about 45 ° beyond the level of the base frame to the underside of the shopping scooter.
  • Fig. 2 The position shown in a solid line in Fig. 2 allows the shopping scooter 1 to be held comfortably when climbing stairs (Fig. 3), the exact setting of the angle of course depending on the gradient of the stairs and also on the size and posture of the operator.
  • the guide tube 6 forms an angle of approximately 70 ° with the plane of the base frame 2.
  • the guide tube 6 can be pivoted so far that the handle 5 rests on the wall 18 which closes off the base frame at the top.
  • the handle 5 connects on both sides at an angle ⁇ of approximately 60 ° to the guide tube 6 and is curved in between in an arc.
  • the handle 5 lies in the plane in which the guide tube 6 can be pivoted.
  • buttons 19 and 20 which are arranged at a distance from one another, considerably facilitates stair climbing with the device. Both when driving upwards and when driving downwards, the operator grips the handle on the grip section between the two control buttons 19, 20, ie on the section of larger diameter that opens into the free end of the guide tube 6. When climbing stairs, where the frame 2 is located behind the operator, the hand grips so that the thumb can be placed comfortably on the control button 19, which is therefore easy to press down.
  • the hand is moved when driving downwards, since the shopping trolley is now in front of the operator. This allows the operator to conveniently put his thumb on the actuation button 20 and press it down so that the device moves.
  • the motor drives the caterpillar tracks upstairs when the control button 19 is depressed and in the opposite direction when the control button 20 is depressed.
  • a separate actuator can be provided for this purpose, which reverses the direction of rotation of the motor.
  • FIGs 3 and 4 show that the wheels 4 cover the crawler belts 3 so that the shopping trolley can roll on the wheels without standing on the ground and stand securely.
