Abstract: A shell for a handle tube of a shopping cart or trolley. The shell has improved properties compared with a conventional, round, simple shell and has zones made of different materials.

Abstract: A flat housing (1) holds a belt (4) which can be extended against the force of a spring, the belt being blocked to further extension as soon as the belt clasp (3) is situated in the belt buckle.

Abstract: A shopping cart or transport container is provided with ion-releasing surfaces that have anti-microbial efficacy. In addition, the surfaces are formed to be hydrophobic or superhydrophobic. The shopping cart or transport container therefore does not provide an environment that permits the survival of pathogens.

Abstract: The invention relates to a shopping cart having a sliding handle, which has module-like functional elements, wherein the functional elements are substantially accommodated in a recess of the sliding handle and protrude so far out of the sliding handle that good usability of the functional elements is given.

Abstract: An advertising frame is disposed as an inverted U-shaped strip around the upper edge of a basket of a shopping cart. The advertising frame is elastic and is placed onto the edge of the basket in a clamping manner.

Abstract: The belt can be pulled out of the housing against a spring force, and the length of the belt is fixed by inserting the belt buckle into the holder.

Abstract: This invention relates to a shopping trolley having castors and a handle, the surface of which consists of plastic. The surface of the handle consists of one or more different materials, at least one of said materials having conductive properties.

Abstract: The invention relates to a display element for attaching advertising to the handle of a shopping cart or the like. The display element includes a base body having a recess for inserting advertising media in a flat manner and fastening elements for fastening the display element on the handle bar, or the handle bar mounts, of a shopping cart. The display element is made of half shell-shaped parts, which in the joined state surround the handle bar, or the handle bar mount, in the shape of an enclosed box profile. The half shell-shaped parts are non-positively or positively connected to the handle bar.

Abstract: Immobilizer for shopping trolleys, wherein the castor angle of the steering rollers when the immobilizer is activated is equal to zero, as a result of which the steering rollers can set themselves stochastically to an oblique or transverse position with respect to the direction of travel, making the shopping trolley much more difficult to push.

Abstract: To generally prevent people from being able to take out and move shopping carts from shopping cart parking areas at times when the store is not open, the blocking devices on the shopping carts are activated when the shopping carts are parked in shopping cart parking areas when the store is not open.

Abstract: Immobilizer for shopping trolleys which is activated and deactivated by means of magnetic forces, in which lower forces are required to deactivate the immobilizer than to activate it. This makes it possible for the immobilizer to be deactivated both by a “strong” magnetic strip, such as is used for activation, and by a “weak” magnetic strip. The “strong” magnetic strip is located at the boundary of the permissible region, and one or more “weak” magnetic strips are located within the permissible region in order to activate immobilizers which are located within the permissible region and are still activated for some reason or another.

Abstract: A method and a system for detecting and rewarding the returning of shopping carts to the supermarket collection points is provided. During shopping, a first signal A is generated. When a shopping cart is returned, a signal B is generated. These two signals A and B are correlated either in the supermarket or in an information device that the customer carries with him or her, in order to deliver a reward for returning the shopping cart. When the first signal A is generated, the customer or an information device carried with the customer is identified. Alternatively, the signal is provided to the customer at the supermarket checkout so that the customer himself/herself can take steps for the correlation of the signal A with the signal B that is still to be obtained.

Abstract: Disclosed is a principle for alternately activating and deactivating a blocking device by means of a magnetic field. A further developed embodiment of the invention is characterized in that the deactivating magnetic field can be smaller than the activating magnetic field.

Abstract: The invention relates to a transport roller 6 for a transfer car, the roller being linked to a bracket and said bracket being rigidly or steerably mounted on the frame of the transfer car. Portions of the bracket (4) and/or the fastening elements (5) are provided with an electrically insulating coating and/or cleading.

Abstract: The purchasing aid is temporarily connected to a housing for the advertising surface which is permanently present, said housing being arranged fixedly on the shopping trolley, wherein the fastening for the purchasing aid is arranged outside the advertising surface, and the advertising surface which is permanently present can optionally also be used as a display for the purchasing aid.

Abstract: The belt can be pulled out of the housing against a spring force, and the length of the belt is fixed by inserting the belt buckle into the holder.

Abstract: The invention relates to an immobilizer for a transport trolley, whereby a magnetic field is used for alternately activating and deactivating said immobilizer. In an embodiment of the invention, the deactivating magnetic field can be weaker than the activating magnetic field.

Abstract: A wheel for a supermarket trolley, includes an immobilizer which is connected to the trolley by way of a simple carrier limb having a shaft fixed thereto. The rim of the wheel is embodied in such a way that, when the wheel is mounted on the trolley, the battery, running surface and other parts can be replaced via an opening that can be closed by a cover.

Abstract: The invention relates to a trolley comprising an element for holding and releasing a token, said element comprising a sensor that detects whether the trolley comprising the element for holding and releasing the token is pushed inside another trolley. If this is the case, the element for holding and releasing the token activates the immobiliser and releases the token. In order to use the trolley, a token must be inserted into the element for holding and releasing the token, thus deactivating the immobiliser.
