Collapsible frame for children's furniture, stroller body and the like.

The invention relates to a frame made of collapsible tubular parts which, in their extended position, form a frame of a piece of children's furniture or a Accessory.

With the invention, a frame can be produced, which, when unfolded, can give the rigid framework of a usable object, but when folded, the rigid parts, In particular, bring metal pipes that form the frame into adjacent and parallel positions that only take up a small amount of space. The invention is particularly useful in the manufacture of children's furniture and accessories, e.g. baby carriers, bodies for strollers, foldable cradles, play stalls or child seats be applied.

The invention relates to a collapsible unit

Parking or transporting to an unused one Position can be folded, with the long parts at least at one end by a set foldable cross sections can be assembled. These cross members consist of rods, each of which is on the one hand is hinged to a support plate and on the other hand at the end of one of the longitudinal parts · The plate on the the rods are hinged, also contains fastening means with which the rods in a radial position and immobilized practically in the same plane, the rods then being brought into the use position and it is ensured that the longitudinal parts are kept at an appropriate distance from one another where the fasteners are not tightened and the bars can be folded and then be brought into positions in which they are parallel to each other and to the longitudinal parts and thus a bundle result.

The invention is explained with the aid of the drawings. In the drawings is

According to the invention, the four parallel longitudinal parts 3j4- * 5 and 6 can be folded against each other and so in the Form a bundle, reducing the space occupied by the frame. The body 6 consists of a cover made of flexible material (fabric, plastic, synthetic or similar).

According to an essential feature of the invention, by folding the rods 7 * 8,9 and 10 and 7'i 8 ¹ , 9 ^f and 10 ^f , the longitudinal parts can be brought into compact form of a bundle, and when they are not folded they serve as a spacer for the long pieces 3 »4-, 5 and 6. The folding of these cross pieces lets the long pieces together take the form of a bundle.

The cross pieces 7? 8> 9 and 10 are with a middle plate 16 connected, to which it is pivotably attached at its end opposite the pivotable end on the longitudinal part are. These cross members can be between an extended position according to Figure 4- and a folded position according to Figure 6 are brought. Figure 5 shows an intermediate folding position.

Figures 1 and 2 show a first embodiment in which the frame according to the invention results in a body or a cradle for a stroller. The upper longitudinal parts 3 and 4 belong to the supports 31 »32, 31 'and 32 ¹ , which are articulated at 33 and 34 and form a hood 30. FIG. 3 shows the use of the frame according to the invention for the construction of a children's playpen. The frame (the elements of which have the same reference numerals as those in FIGS. 1 and 2) belong to protective parts which form a cushion 11 which surrounds the upper longitudinal parts. On the short sides at the top it has a flexible one

Volume 12 and 12 ^l; . On the underside of the upper band 12 and 12 'is the pad 11, which thus follows the edge of the upper edge of the stable.

The folding of the frame is based on the figures 4,5 and 6, where the extended position of FIG. 4 merges into the folded position of FIG. In Figure 6, the transverse parts on the one hand and the longitudinal parts on the other hand are folded into parallel positions and thus result in a bundle (in the figure the Elements away from each other and the fully folded position is used to clarify the illustration Not shown).

According to an important feature of the invention is the connection between a longitudinal part and the associated transverse part attached by a structure that has a Intermediate carrier results and is formed by a spherical ball 15 with a groove 17 at its center is divided by separators and thus two receptacles 19 and 20 for the corresponding ends of the longitudinal part 5 and the transverse part 10 'results. The cross piece and the longitudinal part consist of metal tubes and are rotatably mounted on the spherical carrier, which is attached to a'edem Has a connecting link at the end of the longitudinal part.

The outer surface of the round ball is practically without edges and thus gives the object a pleasant appearance and ensures complete safety by avoiding sharp edges that can injure children's fingers could.

Figures 8, 9 and 10 show the embodiment

a middle plate, which forms the support for the articulation of the foldable cross-sections. The plate 16 belongs to a counter plate 21 in the form of a lid and forms a fastening part which is rotatably fastened to the plate 22 by means of a central hinge 22.

By rotating the counter plate 21, the receptacles 23 and 23 'aligned with the cross members 7 and 8, whereby these move into their extended position according to FIG. The receptacles 23 and 23 'are L-shaped, so that they Can accommodate transverse parts in their locked position, as shown in FIG. 10, by rotating the counter plate 21 in the direction of arrow F by means of the handle 24, which acts on the bearing 22, the cross members are locked in their Position by tongues 25 and 25 'in the manner of a Bayonet attachment held.

The counter plate 21 could also be limited to a four-armed cross, with each arm through the handle 24 can be rotated into the blocking position. i.e. behind each transverse part and thus opposite the angular displacement of the cross piece. The turning of the counter plate and each arm lets this get into a side position or in a hidden position with respect to the transverse part, what a turning and folding to the position according to Figure 8 allows.

FIG. 11 shows another application of the invention in which the frame is surrounded by a corresponding outer cover that has a cot or a baby carrier made. In this case the lower cross pieces extended by hinged, foldable foot parts 26, 27 and 28, which are provided with rollers for easier movement could be.
