Description

Strollers, especially doll strollers

The invention relates to a stroller, in particular a doll's stroller, according to the preamble of claim 1.

5 Such a stroller is known, for example, from DE 38 30 752 C2 or DE 35 32 594 C2 or also DE 37 09 712 Al. These strollers are each characterized by a collapsible chassis, which consists of two parallel vertical planes, hinged to one another, some of them in a scissor-like manner.

10 arranged frame bars and a U-shaped handlebar, whereby corresponding frame bars of the two levels form a pair, and an attachment that has a seat and a backrest. Furthermore, all known strollers have a

15 usually has frame bars that extend diagonally from the top rear to the bottom front, which define the upper limit of the chassis on both sides of the stroller.

Furthermore, child carriers are generally known which comprise a carrying handle, the legs of which are hinged to the side of the carrier in such a way that the carrying handle can be swiveled from an approximately vertical carrying position into a ground support position and vice versa, as well as other intermediate positions if necessary. In this regard, reference is made to US-A 4,986,599 or US-A 5,011,221 as an example. These known child carriers, the sitting and lying sides of which are upholstered, also serve as child seats. For this purpose, they are usually anchored to the rear seat of the vehicle using the seat belts provided in the vehicle, in accordance with European regulations, usually in such a way that the backrest is facing forwards, i.e. that the child lying or sitting in the carrier is facing backwards.

The present invention is based on the object of creating a stroller that can also be used as a doll's stroller and that is designed in such a way that it is suitable for receiving a carrycot of the type mentioned, so that the carrycot can be placed on the stroller and the child or doll in the carrycot can be moved with the stroller. The "carrycot/child" unit should therefore remain unchanged, regardless of whether the child is transported in the vehicle or in the stroller or carried by hand.

This task is solved by the characterizing features of claim 1. Accordingly, the stroller is equipped with support bearings for a carrying shell. The support bearings are detachably connected to the frame bars of the stroller, and in particular can be hooked and locked in place. This also makes it possible to remove the support bearings from the stroller again as soon as the child, especially a toddler, has outgrown the carrying shell.

Alternatively, the support bearings can also be connected to the associated frame beams in a form-fitting and/or force-fitting manner, in particular they can be clamped in place.

Preferably, the support bearing according to claims 9 and 10 has a structurally simple locking device which prevents the support bearing from falling off the frame bars of the child's pram or doll's pram if it is transported in a car or the like.

Furthermore, a locking mechanism for the support bearings on the associated frame bars of the stroller is preferably provided.

The structural design of the support bearings according to claims 2 to 6 is particularly easy to handle. The carrying shell only needs to be placed on the support bearings or on the support plates of the stroller arranged thereon. The carrying shell is preferably equipped with a swivel bearing on both sides, which on the one hand enables the carrying handle to be swiveled into different positions and on the other hand serves to attach the carrying shell to the support bearing or to the support plate. According to the structural design according to claims 13 and 14, the carrying shell is sufficiently rigidly attached to the support bearings of the stroller via the swivel bearings so that the carrying shell mounted on the support bearings cannot carry out any tilting or rocking movements. This also ensures that the carrying shell does not come loose from the support bearings even if the stroller moves suddenly. Each carrying shell swivel bearing includes an easy-to-use locking mechanism that fixes the carrying handle of the carrying shell in a certain desired position. For this purpose, both the parts of the swivel bearings attached to the side of the support shell and the parts of the support bracket assigned to the swivel bearings each have a locking disc that can be rotated relative to one another, the surfaces of which facing one another have corresponding locking projections on the one hand and locking recesses on the other. Using a clamping mechanism, the locking discs facing one another can be easily fixed and released from one another again if a different position of the support bracket is desired.

To further secure the carrying shell on the support bearings, it is recommended to hold it with a strap so that the carrying shell cannot fall out of the support bearings under any circumstances, not even if the stroller tips over. The retaining strap is preferably attached to the support bearings and adjustable in length. To secure it, the retaining strap is passed over the carrying shell, in particular over the foot part of the same, securing the shell to the stroller and locked using a conventional lock.

An embodiment of a stroller or doll's pram designed according to the invention and an associated carrying shell are explained in more detail below using the attached drawing. They show:

used for transport in the car. The carrying shell according to Fig. 1 is marked with the reference number 10. It consists of an ergonomically shaped plastic hard shell 11, the sitting and lying side of which is provided with padding 12. In addition, a triangular safety belt 13 with belt buckle 14 is assigned to the sitting and lying side.

A support bracket 15 is hinged to both sides of the hard shell 11. The support bracket 15 can be pivoted from an approximately vertical support position into a ground support position according to Fig. 1 and vice versa as well as into other angular positions. In Fig. 1 only one pivot bearing is shown and marked with the reference number 60. The pivot bearing comprises, as also shown in Fig. 4, a cylindrical pivot bearing housing 60a, which is arranged on the side of the support shell 10. This housing 60a is assigned a cap-like end 60b on the leg of the support bracket 15. The pivot bearing thus formed is also assigned a locking mechanism in order to hold the support bracket 15 in the desired angular positions 0. The desired locking position is fixed by an actuating button 60c operatively connected to the locking mechanism. The locking mechanism assigned to the pivot bearing is explained in more detail below with reference to Fig. 4. In the position according to Fig. 1, the carrying shell 10 can be placed on the floor, with support being provided on the one hand by the aforementioned carrying bracket 15 and on the other hand by the lower edge 18 of a footrest 19 formed on the carrying shell 10. The carrying shell 10 is designed in the manner of a bucket seat, i.e. provided with lateral support walls 20, 21.

The carrying shell described is intended, among other things, for attachment to the chassis of a stroller, in particular a doll's stroller, as shown in Fig. 2. This stroller or doll's stroller is identified in Fig. 2 with the reference number 22. The chassis of this stroller comprises two beam structures which are spaced horizontally apart from one another and extend parallel to one another in vertical planes.

between which an attachment 23 with a seat 24 and a backrest 25 is arranged. Each bar construction has a main bar 26 extending diagonally from the back top to the front bottom and a support bar 27 hinged to it (joint 28) extending diagonally backwards and downwards. A connecting strut 29 is arranged between the support bar 27 and the main bar 26. So that the stroller can be folded up, the connecting strut comprises two strut sections which are connected to one another via a joint 30. Furthermore, the ends of the strut sections facing away from the joint 30 are hinged to the main bar 26 on the one hand and to the support bar 27 on the other hand (joints 31, 32). When the connecting strut 29 is raised in the area of the joint connection 30 in the direction of the arrow 33, the connecting strut 29 folds together like scissors, with the result that the support beam 27 can also be folded towards the main beam 26 in the direction of the arrow 34.

At the lower ends of the main beam 26 and the support beam 27, a running wheel 35 is mounted so that it can rotate about a horizontal axis 36. The front running wheels 36 can also be mounted so that they can pivot about a vertical axis 37. Since this is a known running wheel design, a more detailed description of it is unnecessary at this point.

As shown in Fig. 2, a support bearing 50 for the support shell 10 is connected to the two main beams 26 in the area between the articulation 28 of the support beam on the one hand and the articulation 31 of the connecting strut 29 on the other hand, and can be hooked in and locked. For this purpose, the support bearing 50 is a component that can be placed on the respective main beam 26 and has a disk-shaped support plate 51 that extends upwards parallel to the planes spanned by the main beam 26 and support beam 27 on each side of the carriage (see also Fig. 3). The associated, cylindrically shaped pivot bearing housing 60a of the

Pivot bearing 60 of the support bracket 15 is placed as shown in Fig. 2.

The mentioned support bearing component has two insertion openings or slots 54 and 55 for receiving laterally outwardly projecting retaining pins 42 and 43 on the main beam 26 or on a fitting 44 firmly connected to the main beam 26. In the assembled state of the support bearing 50 or the associated component, the associated main beam extends through a complementary longitudinal groove in the support bearing component.

This longitudinal groove is open at the bottom so that the support bearing component can be placed on the main beam 26 from above for assembly and moved downwards until the aforementioned retaining pins 42, 43 are completely inserted into the insertion openings or slots 54 and 55. The insertion openings or slots 54, 55 are provided on the outside with laterally protruding covers which cover the laterally protruding retaining pins when assembled in order to prevent injury from the laterally protruding retaining pins 42 and 43.

In the assembled embodiment shown, the insertion openings 54 and 55 are open downwards in a direction parallel to the associated main beam 26, so that during normal operation the support bearing 50 is automatically held in contact with the retaining pins 42 and 43 due to gravity. The support bearing 50 is thus essentially secured on the main beams 26.

However, any other type of locking or arresting of the support bearing 50 on the associated main beam 26 is also conceivable.

A locking of the support bearing on the frame beam 26 can also be provided, e.g. in the form of a locking bolt, which can be passed transversely through the associated component and the side fitting 44 in the position of the support bearing 50 shown in Fig. 2.

As already mentioned, a force-fitting, in particular form-fitting and force-fitting fixation of the support bearing 50 on the main beam 26 and its side fitting 44 is also conceivable.

Specifically, the support bearing 50 is connected to the main beam 26 by means of a clamping or locking device in addition to the positive locking described above, in order to prevent the support bearing 50 from unintentionally becoming detached from the retaining pins 42 and 43 and thus from the main beam 26, for example when transporting the stroller or doll's pram. The insertion openings or slots 54 and 55 each have locking means, namely in the form of two opposing projections 56 which protrude into the insertion openings or slots 54, 55 and reduce the clear width thereof. A single projection protruding into the insertion openings or slots can also serve as the locking means if necessary. It is important that the clear width of the insertion openings or slots, reduced by the locking means, is slightly smaller than the diameter of the retaining pins 42 and 43. When assembling the support bearing 50, it is "locked" onto the retaining pins 42 and 43 by overcoming the narrow point mentioned above. To make "locking" easier, the projections 56 are rounded.

The carrying shell 10 is placed on the support bearing between the frame beams 26, 27 defining the two vertical planes or lateral boundaries of the stroller by placing the swivel bearings 60 of the carrying shell on the support plates 51 mentioned. For this purpose, the swivel bearings 60 assigned to the carrying bracket 15 or their housings 60a are designed to be open at the bottom so that the support plates 51 can be inserted into the housings of the swivel bearings from below. In order to connect the swivel bearing housings 60a of the carrying shell 10 to the support plates 51 in a rotationally fixed manner, two slot-shaped recesses 52 are provided on the support plates 51, which are open at the top and engage with two corresponding web elements 63 arranged in each swivel bearing housing 60a and pointing downwards.

For a rotationally or tilt-proof connection between the support plates 51 and the associated pivot bearing housings 60a, it is also sufficient if the support plates 51 each have only a single slot-shaped recess 52 that is open at the top and corresponds to a downward-facing web element 63 of the pivot bearing housing 60a.

Conversely, the support plate 51 can also have upwardly directed retaining pins or web elements, which are each received in complementary, downwardly open receiving openings of the pivot bearing housing 60a assigned to the support bracket 15.

To further support the pivot bearing housing 60a on the support plate 51, the latter has a radially protruding projection 53 on its peripheral edge, which is held in contact with the pivot bearing housing 60a or its peripheral edge 62 as soon as the support plate 51 has fully engaged with the pivot bearing housing 60a.

By additionally supporting the carrying shell 10 attached to the support plate 51 on the seat surface 24 of the stroller, an unintentional pivoting of the carrying shell against the support plate 51 to the front or back is completely prevented. To additionally secure the carrying shell 10, retaining straps 44 (not shown) are connected to the support bearings 50, which can be guided and locked over the carrying shell 10 while securing it to the stroller 22 if necessary, with locking taking place in the conventional manner. As mentioned at the beginning, each pivot bearing 60 has a locking mechanism by which the desired angular position of the carrying bracket 15 of the carrying shell 10 can be set and locked. The locking mechanism comprises two locking disks 61 and 67 that can be rotated relative to one another, of which one disk 61 is part of the pivot bearing housing 60a and the other disk 67 is part of the support bracket 15 or the cap-like end 60b of each support bracket leg. The two surfaces of the locking disks 61 and 67 facing one another have

&Iacgr; &id;.· ! &iacgr; * i &idgr;♦ j»» _t

other corresponding locking projections 66 on the one hand and locking recesses 64 on the other. The locking recesses are located on the locking disk 61 assigned to the pivot bearing housing 60a and are evenly distributed along the circumference of the locking disk 61 or arranged equidistantly both from the center of the disk and from one another. The locking projections 66 are also arranged in a corresponding manner along the circumference of the locking disk 67 assigned to the end 60b of each support bracket leg. The angular distance between adjacent locking projections 66 or locking recesses 64 determines the smallest angular adjustment of the support bracket. The two locking disks 61 and 67 are fixed by an axially effective clamping mechanism. For this purpose, the locking disk 61 on the swivel bearing housing side comprises a centrally outwardly projecting threaded pin 65 which extends through a central opening 68 of the cap-shaped end 60a of the support bracket 15. The centrally projecting threaded pin 65 defines the axis of rotation about which the locking disks 61 and 67 of the swivel bearing housing 60a and the end 60b of each support bracket leg can be rotated relative to one another. An actuating button 60c or the like designed as a nut can be screwed onto the end of the threaded pin 65 protruding through the central opening 68, by means of which the two locking disks 61 and 67 can be fixed relative to one another. In the assembled state, the actuating button 60c is placed within the outwardly open recess of the cap-shaped end 60b of each support bracket leg.

When the support bracket 15 is fixed in a certain angular position, the distance between the locking disks 61 and 67 is reduced until the locking projections 66 of the locking disk 67 on the support bracket side are pressed into the corresponding locking recesses of the locking disk 61 on the pivot bearing housing side, so that rotation of the locking disks relative to one another is prevented. By using rounded or spherical cap-shaped locking projections 66 and correspondingly rounded locking recesses 64, it is not necessary to move the locking disks against one another when fixing them.

other so that the locking projections 66 are located directly above the locking recesses 64. This design measure causes the locking projections 66 to slide into the corresponding locking recesses even if the locking projections and locking recesses are partially offset from one another.

The two upper ends of the main spars 26 are connected to one another by a connecting strut, which together with the main spar 26 defines a U-shaped handle bar 54. Alternatively, the upper ends of the main spars 26 can also be designed as separate handle bars.

It should also be noted that Fig. 2 shows the placement of the carrying shell on the support bearings or on the support plates 51 associated with them. The support bearings 50 are already fixed on the respective associated main beams 26, so that the stroller is ready to receive the carrying shell 10.
20

The support bearings 50 are each made of plastic.

They can be removed as soon as the child has outgrown the carrycot 10; then the support bearings 50 are also no longer required. The stroller can then be used in the usual way. The same applies to doll strollers.

All features disclosed in the application documents are claimed as essential to the invention insofar as they are new, individually or in combination, compared to the prior art.
