DE102008045063A1 - Cradle for use in coaster wagon and/or drawing car that is utilized by child, has body that is fixed in mounting bracket, at which chassis for cradle and/or coaster wagon and/or drawing car is attached - Google Patents

Abstract

The cradle has a body (10) that is fixed in a central, u-shaped mounting bracket (20), at which a chassis (30) for the cradle and/or coaster wagon and/or drawing car is attached. The bracket is designed in form of an oval profile. Geometry of the body and the mounting bracket are coordinated with one another. The bracket is formed of multiple profiles, and a circular or partial circular rail (12) is fixed at the body. Side parts (11) are provided between the body and the rail in a spatial limited manner. Storage elements are attached at horizontal or perpendicular parts of the bracket.

Description

State of the art:

Among others, according to the utility model DE 29700933 U1 are known weighing, which can be converted into a wagon / pull cart.

Problem:

The Utility Model DE 29700933 U1 has, among other things, the problem that the lower part of the cradle can not be used later and that the cradle is limited in the height position, that can not be adjusted. In addition, it is not particularly easy to attach a variety of attachments for both functions. The aim is therefore to develop a cradle, which can be easily converted into a wagon / pull cart, with as few parts as possible, which are used in just one use. According to the customer's request, the components should be able to be put together according to a modular system. In addition, the cradle or the Bollerwage / Ziehwagen should be designed so that extremely simple and stable various elements (such as flags, sun protection, cradle sky, storage table) can be adapted for both functions.

The solution of the problem:

This problem is solved by the features listed in the protection claim 1. It is particularly advantageous that in both uses of a single, ideally stable, central support element ( 20 ) both the shell / body ( 10 ) as well as the chassis ( 30 ) with the wheels attached thereto ( 33 )/Roll ( 32 ) is attached. This type of modular system allows the customer to assemble the individual parts with a wide variety of surfaces, etc. In addition, this also gives a particularly simple decomposability. When the shell ( 10 ) consists of a rigid / stable U-shaped element, there is also the particular advantage that the most diverse, the customer's request, side panels / side walls ( 11 ), as these do not contribute to the stability of the shell ( 10 ) contribute. This means maximum flexibility of the shell / body ( 10 ) at maximum overall stability. This principle is not carried out in any of the known weighing or Bollerwagen / Ziehwagen. Particularly advantageous is then a large height of the two legs, as this can serve as a back support in children for the wagon. A particularly stable and shapely design variant is the U-shaped curved shell ( 10 ) with rounded corners. This also applies to the central mounting bracket ( 20 ), wherein ideally both geometries / radii are coordinated in terms of maximum compactness and beauty of form. An advantageous Ausgestaltunsgvariante is now that the central mounting bracket ( 20 ) can be changed in height. This is done either via an inside or outside connector ( 21 ) or via a telescope-like system that allows a stepless or multi-stage adjustment. As a result, in the weighing function of the body ( 10 ) on z. B. bed heights or other relevant dimensions can be adjusted. The central mounting bracket ( 20 ) can be formed from a profile or even from 2 profiles, which offer here in addition to rectangular profiles and oval or round profiles. Is particularly vorteilhat is when the upper portion of the central support bracket ( 20 ) is designed so that there various elements can be attached and also here the rotation axis and rotation possibility of the weighing function is ensured. Ideally, on the central mounting bracket ( 20 ) also other storage levels, etc. are attached. It is also advantageous if on the shell ( 10 ) a kind of circulating or at least partially circumferential railing ( 12 ) is attached. This serves for stability and impact protection. Also, between railing ( 12 ) and shell / body ( 10 ) very easy the side parts ( 11 ), the railing ( 12 ) in this case preferably on the bottom has a slot in which the side part ( 11 ) is guided. When guiding on the shell ( 10 ) is also a slot or a U-shaped receptacle possible. A further advantage is that on the boom-like chassis ( 30 ) both the roles ( 32 ) for the cradle and the wheels ( 33 ) can be attached to the wagon. About add-on elements ( 31 ) on the chassis while the Auflagerbreite and thus the stability can be increased. In the wagon version is thereby the front axle / the front chassis on the central mounting bracket ( 20 ) rotatable about the vertical axis and there also the drawbar ( 37 ) for pulling the car.

EXAMPLES

Some embodiments of the invention will be described with reference to FIGS 1 - 6 described in more detail: 1a -C shows the state forms of weighing and Bollerwagenfunktion and how the conversion can be achieved preferably. In 1a one recognizes a central, U-shaped bent mounting bracket ( 20 ), represented in the form of an oval profile. In this mounting bracket ( 20 ) is the shell / body ( 10 ) rotatably mounted and fixed for the weighing function. This is ideally achieved via integrated fasteners ( 13 ) in the shell and bearing-like support elements ( 22 ) at the upper part of the central support bracket ( 20 ). About a suitable locking the determination of the shell is achieved, so that then the cradle can be safely moved / rolled. In the lower, horizontal area of the carrying handle ( 20 ) are via fasteners ( 24 ) in the mounting bracket ( 20 ) two cantilever-type landing gears ( 30 ) with add-on elements ( 31 ) and roles ( 32 ) appropriate. The shell ( 10 ) has a circumferential railing ( 12 ), which on the shell ( 10 ) is attached. The railing ( 12 ) serves as an impact protection and this the cradle can also be moved. Between railing ( 12 ) and shell ( 10 ) are the side parts ( 11 ), which are ideally transparent, or may have any other color, pattern, or motif. The shell ( 10 ) itself may also have slots or openings to allow ventilation of the mattress ( 15 ) from below. In the 1b it can be seen that the central mounting bracket ( 20 ) preferably consists of individual parts and thus the total length of the two legs and thus the height of the overall system can be changed. This is done here by internal connecting elements ( 21 ) guaranteed. 1b also shows the conversion to Bollerwagenfunktion, simply the previously mentioned height of the support leg is shortened. The support element / receiving element ( 22 ) at the upper part of the support bracket ( 20 ) can also be used here, the rotation function is eliminated. The jib-like chassis ( 30 ) are attached to the underside of the carrying handle ( 20 ) in contrast to the weighing function slightly offset inwards and mounted on the wheels ( 33 ), whereby the front axle, on which also the drawbar ( 37 ) is attached, then rotatably mounted.

The displacement of the two chassis parts inwards has as a positive consequence that the wagon is as compact as possible and can be stowed completely in the trunk. In the other case of the weighing function is rather a maximum stability required, which is achieved by the widest possible distance of the chassis parts from each other. At the bottom of the carrying handle ( 20 ) are here einsprechende Befestigungsigunsgelemente ( 24 ) for the landing gear. The drawbar ( 37 ) is ideally designed bent in the lower part and can in the sense of maximum compactness to the shell ( 10 ) and then shortened.

About fasteners to shell ( 13 ) and corresponding fastening elements ( 23 ) on the mounting bracket both parts are positively connected with each other or the shell is simply attached to the mounting bracket ( 20 ) screwed.
