DE19729049A1 - Shopping trolley handle system - Google Patents

Abstract

The shopping trolley handle system consists of three individual main components. Between two ergonomically designed handles, there is a functional part. The individual parts are fixed to, but can be detached from, each other and the wire basket of the trolley. The fixing part is in the form of an anchor rod passed through cavities in the handles and the functional part. Alternatively, conventional elements such as screws or pins may be used. The functional part is made of plastics or aluminum by the string casting process, whereas the handles are made by the plastics injection process.

Description

DESCRIPTION

The device according to the invention is a new type of handle for shopping dare that has advantages over the prior art.

A so-called handle system is provided, which consists of several components that are different manufacturing processes can be produced, on the other hand the practical Requirements in terms of ergonomics and functional quality in a form not previously available satisfy.

FUNCTION

The function of the handle system is largely limited to the technical structure - in the example:

The handles ( 1 ) left / right are ergonomically designed and serve on the one hand to fasten the handle system to the wire frame of the shopping trolley and on the other hand to fasten the functional part ( 2 ) arranged between the handles ( 1 ). The functional part ( 2 ), preferably manufactured in inexpensive plastic (or aluminum) continuous casting processes, has, in addition to inner contours for producing the required statics, outer contours ( 3 a) in the longitudinal axis for receiving and locking the cover of the transparent advertising window ( 3 ). In each case, right / left of the advertising window, fitting parts ( 4 ), ( 5 ) can be arranged, which can be designed to be displaceable (position 5 a) such that the gap between the advertising window ( 3 ) and fitting part ( 5 ) that arises during the displacement can be used with a simple tool that can be released in the contours ( 3 a) locked by self-locking cover of the advertising window ( 3 ).

Another option for removing the cover of the advertising window ( 3 ) from the contours ( 3 a) is that contact with the contour ( 3 a) via a hole ( 6 ) made on the underside of the functional part with a pin (screwdriver or the like). can be produced and which is locked in this locked cover of the advertising window ( 3 ) from self-locking. Under these technical requirements, the change of advertising medium is guaranteed with the least possible expenditure of time in a previously unavailable form.

The functional part can, preferably on the underside, have additional bores (housing openings) be provided, via which, for example, other functional parts, such as coin deposit locks, positionally secure on Functional part can be locked.

To improve the statics of the handle system, an anchor rod or suitable fastening elements can be guided through the inner cavities of the handles ( 1 ) and the functional part ( 2 ) in order to securely connect these components to the wire basket of the shopping cart.

Claims (7)

1. shopping trolley handle system, consisting of three individual main components, characterized in that a functional part ( 2 ) is arranged between two ergonomically designed handles ( 1 ) - the individual parts are firmly but releasably connected to one another and to the wire basket of the shopping trolley - the fastening part ( 7 ) is an anchor rod guided through internal cavity contours ( 8 ) of the handles ( 1 ) and functional part ( 2 ) or conventional elements such as screws, pins or the like. 2. Device according to claim 1, characterized in that the functional part ( 2 ) consists of plastic or aluminum and is made in the so-called continuous casting process, whereas the handles are made in the plastic injection molding process. 3. Device according to claim 1 and 2, characterized in that the functional part ( 2 ) on the top has an as an advertising window ( 3 ) formed transparent cover, which is locked in longitudinal contours ( 3 a) by self-locking. 4. The device according to claim 3, characterized in that the functional part ( 2 ) on the underside has at least one bore ( 6 ) through which access to the locked in the contour ( 3 a) advertising window ( 3 ) is made - thereby in the easiest way with commercially available tools (steel pin or the like), the locking of the cover of the advertising window ( 3 ) produced by self-locking in the contour ( 3 a) can be released. 5. Apparatus according to claim 1 to 3 characterized in that right and / or left of the advertising window ( 3 ) fitting parts ( 4 ) ( 5 ) are arranged, which are also locked in the contour ( 3 a) by self-locking, of which, however at least one is designed to be displaceable (item 5 a), so there is the option of locking the advertising window ( 3 ) in the contour ( 3 a) via a gap that can be produced in this way between the fitting part ( 5 ) and the covering of the advertising window ( 7 ) with a suitable tool to solve. 6. The device according to claim 1 and 2, characterized in that the handles ( 1 ) are not mirror images. 7. The device according to claim 1-6, characterized in that the functional part ( 2 ) can be made of more than one component.
