Definitions

  • the invention is directed to a stroller, comprising a chassis with front struts, rear struts, a push bar and side hinges with connections for each leg of the push bar and / or a front strut and / or a rear strut, as well as an attachable thereto essay.
  • Strollers should be universally applicable, while comfortable, functional and stable during use; In times of non-use, prams, on the other hand, should disturb as little as possible, so take up as little space as possible. Especially the last condition is probably the hardest to fulfill, because this can only be achieved by an efficient folding mechanism. However, it is not enough to provide joints at suitable places; rather, these articulated joints should be as stiff as possible in the unfolded state, so that the stroller receives sufficient stability. On top of that, the adjustment of the joint should still be as simple and comfortable as possible.
  • the article has a frame for the backrest or for a seat recess and / or for a hood, which can be fixed to the chassis in the region of the articulated joints, and frame parts and / or flat body for supporting the seat of the Aufsatzes, wherein the frame parts and / or flat body of the seat of the essay are mechanically not connected to the frame for the backrest or for the seat recess and / or for a hood, but possibly on the (reference) fabric of the essay for the backrest or for a seat recess and / or for a hood.
  • the attachment extends at least partially between the articulated joints, it can make itself disturbing when folding the chassis by means of these joints. In particular, care should be taken to ensure that the chassis is easily folded up so that sufficient space is reserved for a largely rigid attachment, even when folded up. On the other hand, thereby increasing the footprint of the stroller in the folded state, which od, for example, when stowed in a trunk. Like. Unfavorable.
  • the attachment according to the invention is highly flexible because it not only knows one possible direction of movement, such as a joint, but allows different relative movements and, in particular, a superposition of different relative movements, depending on how the folding process requires this. So there are no other joints in addition to the two joints, in particular not in the area of the essay.
  • an adapter is integrated or fixed or fixable on a joint, with which various attachments can be attached to the chassis of the stroller, such as baby carts, sports or buggy seats, reclining seats similar bags, etc. So that's different Towers interchangeable, which can be customized depending on the advancing age of the child's body size.
  • the invention further provides that two lateral articulated joints are not directly connected to one another, in particular not by a straight bar or the like. Due to the absence of such a direct connection, on the one hand space is created in the area between the two joints for the construction of a possibly also somewhat larger Aifsatzes, and on the other hand, the child seat can thereby be folded apart and without any clamping apart.
  • the invention can be further developed such that a fixed to the chassis essay dips into the area between the two lateral joints. This can reduce the seat height for a child, whereby the center of gravity of the loaded essay is reduced and thus the risk of tipping over is considerably reduced.
  • struts can extend directly to the front and rear wheels, which include a right or even acute angle in the area of the hinge connection, resulting in a comparatively simple construction with simultaneously high stability.
  • the seating surface of the attachment should be below the line connecting the two lateral joints.
  • the backrest of the attachment should be located behind the connecting line between the two lateral joints. By doing so, the child's center of gravity lies almost exactly on the line connecting the two lateral ones
  • the top of the attachment can be located above and / or behind the connecting line between the two lateral joints. This design specification serves the purpose of optimally trimming the stroller.
  • the Austarians of the stroller is also another requirement, after which a safety bar of the essay above and / or in front of the line connecting the two lateral joints.
  • each one or more linear guides are provided for inserting a lateral connection part on an essay on the inner sides of the housing of the articulated joints, so that a releasable connection to various, assembled and removable and thus exchangeable essays is created.
  • the invention can be further developed in that at least one linear guide has a groove-shaped cross section, preferably with lateral undercuts similar to a dovetail joint.
  • a fixed thereto essay can only be solved in the sliding direction of the linear guide of the chassis.
  • the invention recommends that the tower-side pendants are connected to the linear guides on the two articulated joints by a bracket with a U-shaped course.
  • a bracket encompasses the body of a child in a spacious way and leaves this enough space and freedom of movement.
  • Such a U-shaped bracket connects the tower-side counterparts and at the same time can form a framework or a frame for the essay, wherein the backrest of the essay on this set, forwardly extending side parts of the cover fabric on the U-shaped bracket be fixed or fixable can.
  • the backrest of the essay can be connected or connectable in the region of its upper edge with the central web of the U-shaped bracket. As a result, the backrest is relieved and can be made relatively soft, for example made of textile.
  • the direction of the U-shaped bracket is given. Its level should extend from the connecting line between the two joints upwards, but at the same time away from the line connecting the two joints in the direction of travel of the stroller, ie forward or backward, depending on the direction of travel of the stroller.
  • An advantageous development provides that the seat hangs on the backrest and possibly on associated side parts. Such a loose connection prepares no problems when folding the stroller.
  • the two side legs of the U-shaped bracket can be transferred to other tasks.
  • the side parts of a top can be fixed to it, in particular joints that allow it to be folded together and unfolded.
  • the backrest is preferably fixed to the central web of a U-shaped bracket, the hood should indeed be pivotable forward over the backrest.

  • this lower leg support can be folded down. The then no longer disturbing plate allows a normal sitting position, the lower leg enclose an approximately right angle with the thighs. If the seat of the essay in its front region has an approximately tab-like extension which is formed as a pocket, the lower leg support can be inserted therein. This follows the relevant, lobe-like region of the seat of the respective position of the fold-away lower leg support.
  • a front or rear strut is integrated with the housing of the articulated joint or fixed thereto, while the other front or rear strut on the respective side of the chassis and a side leg of the push bar relative to the housing of the hinge connection are pivotally mounted, namely by two different pivot axes, which are preferably aligned parallel to each other, but not coaxial to each other, but eccentric to each other, so that z.
