A disadvantage of this prior art is that the push rod always remains as a bulky element on the car frame, which defines the size of the collapsible state. Furthermore, it is problematic that the car frames are constructed heavyweight, to ensure adequate stability in the unfolded state. Finally Cart racks require according to the prior art even when folded a relatively large storage space.

The object of the present invention is therefore to avoid the known from the prior art disadvantages and in particular to keep the space provided by the carriage frame required in the unused state, as small as possible. In addition, should be adapted in order to arrange universal use on the car frame can the carriage frame. The inserts and attachable elements are in particular to baby seats or child seats. Furthermore, it should be given an extended benefits.

This object is achieved by the invention by designing the carriage frame according to the features specified in claim. 1 Advantageous embodiments of the invention are evident from the dependent claims, the description and particularly the description with reference to a specific embodiment.

A generic carriage frame is characterized in that the sliding rod at the rear of the base member is pivotally supported and at least in the erected position by means of locking means on the base element obliquely upwards and backwards, the rear wheels on standing, is held and the back after releasing the locking means and after a folding in a horizontal extension to the base element position on, in or below the base member in a stowed position from rear to front is displaceable.

Due to the invention are given two significant advantages. The center of gravity of the stroller is always located in front of the rear wheels, almost in the central region of the base member. On the other hand, the push rod with the top side handle of the person pushing is freely operated, since the push rod the rear wheels on stands at the top. This also has the advantage that when riding on curbs a large torque is possible by pressing the handle on the push bar to lift the front wheels on the sidewalk can. Furthermore, the carrier that receives the application, be driven down before the push rod is folded back and completely stowed in the base member. Even the handle at the top end is not or only imperceptibly stands the rear wheels, depending on the design. Even with heruntergestelltem support the stroller can still be used as such. This is especially advantageous when heavy toddlers in the child seat sitting. The carrier with the child seat can therefore be used both in the lowest position and in a mounting position on the slide bar. In the down position, the carrier or a board attached thereto serve as porters.

To fix the carrier at an altitude is provided in a further embodiment, the at least one push rod is a profile tube with lateral longitudinal guides for fastening means to the support and is combined as a single push rod or with such other parallel, both running parallel to the central axis of the base element are arranged. On the inner side of the guide or the recess in the carrier may project as the fastening means of bolts or it may also be formed, a rib, so that the carrier can be guided in from above in the profile. The push bar itself has a profiled base and a retractable top, which can be pulled or pushed telescopically upwards in order to make such a height adjustment of the grip level on the size of the person pushing can. The locking means for locking the upper part in the bottom are well known. For example, in the profile of the lower part of the push rod back holes may be provided in the inside of a provided latching pin can be pivoted at the upper part. For this purpose, the actuating elements are provided at the upper part. Conversely, however, may also be mounted a spring-loaded locking pin on the rear side of the lower part of the push rod which engages through a bore in the mantle wall through a hole in a row of holes on the congruent wall of the upper part of the push rod.

The fixing of the support at different levels can be done by similar locking means or else. By adjustable clamping or locking elements on the support or to the push-rod, which cooperate with counter-elements on the carrier, or of the push rod The carrier is adjustable in height so attached to the invention at least one push rod and verbringbar from an upper position of use in a lower, decoupled from the pusher bar use position, in which the carrier is seated on a head portion of the base member. In or on the base element or the head part and in the support at least one rear recess and a fixing means for fixing in position the at least one push rod are provided at least in the erected position. After loosening of the fastening means the push rod is pivoted to the rear and can, if before the carrier is moved to the lower position, are pushed below or into the base element. Also there may be provided, which hold the push rod in the retracted position, so that the folded carriage frame can be hung for example on the handle to a wall hook latches.

For mounting an insert on the support is provided in a further embodiment, the holding device consists of a U-shaped support whose side legs in a position of use are up and the bridge part is pivoted to, or mounted in the front of the carrier and at the leg ends connecting parts mounts for the adapters are rotatably mounted, which are forming with the other ends to the leg ends of a further U-shaped beam, a force parallelogram articulated, and in that the bridge part of the further U-shaped beam in at least one oblong hole in the carrier in the direction push rod is displaceably guided or is also pivotably mounted in a through bearing bore to the rear. When the second U-shaped support is also pivotally mounted, so the lowering exclusively on the moving back of forces is effected with simultaneous lowering of the lateral connecting parts. Here, other recordings may be used. In regard to the required stability of the connection between the insert and the carrier but an embodiment has proved using a parallelogram of forces to be advantageous. This embodiment has the advantage that the attached to the connecting parts adapters can be spent together with the use of backward toward the push rod. The use is formally on the carrier. If the bet is a seat insert, this may consist of two bars, the upper bracket on the bottom can be swung so that the drilling depth can be reduced by about half, and after the removal of the support in the lowest position of use the front wheels does not protrude.

An advantageous embodiment of the base member states that this consists of a tunnel profile, is fully up and covered for the push rod having an insertion channel. The base member may also consist of two symmetrically designed and arranged profiled longitudinal beams which, on face on a bridge element on which the at least one front wheel is installed, and are back, joined together over the headboard on which the stock holders are attached to the rear wheels wherein the at least one push rod is pushed into the tunnel profile or between the two longitudinal members. With the base member, the storekeeper for the rear wheels over the headboard are connected and this formed as a rocker which can be pivoted upwards against the force of a spring, whereby a damping is given when driving a road. are the rear wheels at the ends of the wings.

These arrangements are known. the bearings for the front wheels are located at the fork ends 2. This arrangement is an increased tipping safety given. In principle, however, a single bearing holder 6 may be provided on a front wheel 2 also on the bridge element 29; in this case would be given a three-wheel design of the carriage frame.

As shown in the illustration can be seen, the push rod 3 on both sides longitudinal guides 18. These longitudinal guides 18 can rows, as the dark dots show exhibit. The longitudinal guides 18 are provided both on the one and on the other side. When the upper portion 37 of the push rod 3, which in the lower part is telescopically inserted, pulled upward, the carrier 9, the longitudinal and rear side has an opening and on the inside protruding guide lugs which engage in the longitudinal guides 18, the shift rod to be postponed. It is appropriate, also form the longitudinal guide 18 in the carrier 9 as a recess and the back must be open, so that even when not completely pulled out, the upper portion of the push rod 3 the carrier 9 to the lower portion of the push rod 3 is placed. Not locking lever shown can be swung into the bores for taking different height positions, so that the carrier 9 can be arrested in different height positions.

From the isometric view in <figref idrefs="f0005">FIG 9</figref> is further evident that the profile with the longitudinal guides 18 terminates above the head portion 20 in a free cut 38th The cutout 38 is adapted in height so that when the carrier 9 moves downwards and, as seen from the<figref idrefs="f0006">FIG 13, 14 and 15</figref> it can be seen, the head part 20 on inside out, the guide elements, there are bolts or sliding ribs which slide 18 along the longitudinal guides, slide out of them and into the cut-38th It is from<figref idrefs="f0006">FIG 14</figref> seen that then the push rod 3 is pivotable after releasing a locking device on the head part 20, not shown, downwardly and rearwardly, to be pushed into the base member 5 can.

Taking the lower position of the carrier 9 is shown in <figref idrefs="f0006">FIG 13, 14 and 15</figref> shown. <figref idrefs="f0006">FIG 13</figref> also shows that in this position, the carriage frame is still fully usable. Therefore, if the there drawn insert 4 is replaced by another, the carriage frame can be used for example as a pushchair frame with a special shell seat or it can also be mounted cargo area. The carrier 9, the z. B. may be made of plastic or metal injection molding, has for weight reduction side portions with long holes 39. The U-shaped support 24 is pivotally mounted on the carrier 9 and has upwardly projecting legs, at which connection members 23 are hinged. The connecting parts 23 are also made of plastic molded parts, which are connected to the free legs 22 of the front-side U-shaped beam 21st This U-shaped support 21 is rotatably mounted in the front part of the carrier 9, so that, as from the<figref idrefs="f0006">FIG 11</figref> is ff. seen the unexampled than force parallelogram structure can be moved backward.

The holding apparatus 10 further has, at the U-shaped support 21 on a support portion 35 which supports the legs 22 of the U-shaped carrier 24 in the erected state. Again over can take place a lock in the erect position. At the connecting parts which are provided on both sides of the holding device 10, receptacles 25 are provided for adapter 19th These adapters 19 are secured to the pivots 36 of a removable insert. 4 By dissolving a compound, not shown, so the insert 4 can be removed with the adapter 19th

The insert 4 is a seat insert and consists of a lower bracket 31 and an upper bracket 30. On the upper transverse bar of the strap 30 is a cloth insert 32 attached, the seat is shaped below deflected and fixed to a front transverse rod 33rd Characterized a seat is created. When the upper bracket is pivoted 30 about the hinges 36 forward over the lower bracket 31, the fabric is shortened, so that the carrier 21 and 24 to the back can be pivoted about the pivotable U-shaped and can be lowered at the same time, as seen from the<figref idrefs="f0006">Figures 11 and 12</figref> is visible. The carrier 9 can be moved over the headboard 20 down, as previously described, to the push rod 3 from the<figref idrefs="f0006">FIG 14</figref> to pivot position shown and then according to <figref idrefs="f0006">FIG 15</figref> be inserted into the channel of the base member 5 can.

To push the carriage frame is, the push rod 3 provided a bearing head 27 at the upper end of the upper section 37, in which a push bar 26 is either rigid or movably supported by an open angle. This handlebar 26 can also actuate a braking device with flexible storage at the same time. Furthermore, he has in the exemplary embodiment of the mutually protruding ends on handles 34, the example, the hand of a person pushing can be placed.

From the collapsed position in accordance with <figref idrefs="f0006">FIG 15</figref> , the frame in the reverse manner from the <figref idrefs="f0006">FIG 10 to 14</figref> is seen to be set up again until it reaches the in <figref idrefs="f0006">FIG 10</figref> Side view shown assumes that in the isometric view <figref idrefs="f0005">FIG 9</figref> matches.
