Description

P123010NL00 Title: A backrest structure and a buggy, stroller or pushchair The invention relates to a backrest structure for a buggy.
Backrest structures for buggies are generally known for comfortably carrying young children in a buggy. A buggy commonly has a carriage frame with wheels supporting the frame. Further, a buggy is provided with a backrest structure that is permanently or releasebly mounted to the carriage frame. Buggies are mostly foldable to a collapsed state for compact transport and storage.
Backrest structures for buggies can also be foldable. Typically, foldable backrest structures include a movable frame including tubes that provide a poor comfort for the child. Also, the backrest structures may still occupy a relatively large space volume. Further, backrest structures are generally relatively heavy due to requirements in terms of foldability on the one hand and stability and comfortability during use on the other hand.
It is an object of the present invention to provide a backrest structure for a buggy that is foldable but is also relatively light and stable. Thereto, according to an aspect of the invention, a backrest structure is provided, comprising a bottom backrest portion and a top backrest portion, both backrest portions having a mainly rectangular contour formed by a bottom edge, two side edges and a top edge, the backrest portions being hingeably mounted to each via a main hinge structure connected to the top edge of the bottom backrest portion and the bottom edge of the top backrest portion, the backrest structure further comprising a side backrest portion extending along at least a substantial portion of the bottom and top backrest portions and being hingeably attached to the side edges thereof via a side hinge structure, wherein the side backrest portion includes a bottom side backrest portion and a top side backrest portion that are mutually hingeable via an auxiliary hinge structure that is mainly aligned with the main hinge structure.
By providing a backrest structure having a bottom and top backrest portion that can be folded relative to each other, its length can be reduced considerably, in the folded state.
Further, by applying a side backrest portion that can swivel along a longitudinal axis, along the side edge of the bottom and top backrest portions, a relatively stiff, stable support construction is obtained, as the combined backrest unit has a large bending stiffness along said longitudinal axis, due to the folded backrest configuration.
Then, the backrest structure can be implemented as a relatively light weight, cheap and simple unit.
Further, the side backrest portion contributes in providing a comfortable side support to a child lying or sitting on the backrest structure.
On the other hand, by providing a auxiliary hinge structure that is mainly aligned with the main hinge structure, bottom and top side backrest portions may swivel together with the bottom and top backrest portions, thereby enabling the backrest structure to fold as well to result in a compact collapsed structure, ready for transport and storage.
Advantageously, the side backrest portion may swivel upwardly, e.g. induced by an upwardly oriented biasing force, when the top backrest portion swivels downwardly i.e. towards a complete open folded state wherein the bottom backrest portion and the top backrest portion are mainly mutually aligned.
Then, the side backrest portion may provide additional stiffness to the overall backrest structure.
Similarly, when the top backrest portion swivels upwardly i.e. from a complete open folded state to the folded state, the side backrest portion may swivel downwardly to a position wherein the side backrest portion and the bottom backrest portion are mainly mutually aligned so as to facilitate that the top backrest portion and the top side backrest portion may swivel via the main hinge structure and the auxiliary hinge structure, respectively, towards the bottom backrest portion and the bottom side backrest portion, respectively.
Preferably, the backrest structure has side backrest portions to the left and to the right of the bottom and top backrest portions, thereby providing a balanced design.
Advantageously, the main hinge structure may include two folding lines that are mainly parallel to each other, thus simplifying an folding action and making it easier to obtain a collapsed backrest structure wherein the bottom and top portions are completely folded, extending on top of each other in a mainly parallel orientation.
Preferably, the auxiliary hinge structure includes two folding lines that adjoin a corresponding folding line of the main hinge structure and run therefrom in a tapered manner so as to enable the backrest structure to fold even if the side backrest portions are somewhat tilted upwardly from the top and bottom backrest portions.
The backrest structure may further comprise a seat base portion that is hingeably connected to the bottom edge of the bottom backrest portion, so as to provide an integrated backrest structure supporting both seat and back of the child.
The invention also relates to a buggy, comprising a carriage frame and wheels supporting the carriage frame, further comprising a backrest structure connected to the carriage frame.
Further advantageous embodiments according to the invention are described in the following claims.
It should be noted that the technical features described above or below may each on its own be embodied in a foldable cot, i.e. isolated from the context in which it is described, separate from other features, or in combination with only a number of the other features described in the context in which it is disclosed.
Each of these features may further be combined with any other feature disclosed, in any combination.
The invention will now be further elucidated on the basis of a number of exemplary embodiments and an accompanying drawing. In the drawing: Fig. 1 shows a schematic perspective view of a buggy having a backrest structure according to the invention, in a lying state; Fig. 2 shows a schematic perspective front view of a backrest structure according to the invention, in the lying state; Fig. 3 shows a schematic perspective rear view of the backrest structure shown in Fig. 2, in the lying state; Fig. 4 shows a schematic perspective view of the buggy shown in Fig. 1, in a sitting state; Fig. 5 shows a schematic perspective front view of the backrest structure shown in Fig. 2, in the sitting state; Fig. 6 shows a schematic perspective rear view of the backrest structure shown in Fig. 2, in the sitting state; Fig. 7 shows a schematic perspective view of the buggy shown in Fig. 1, in a folded state; Fig. 8 shows a schematic perspective front view of the backrest structure shown in Fig. 2, in the folded state, and Fig. 9 shows a schematic perspective rear view of the backrest structure shown in Fig. 2, in the folded state It is noted that the figures show merely a preferred embodiment according to the invention. In the figures, the same reference numbers refer to equal or corresponding parts.
Figure 1 shows a schematic perspective view of a buggy 10 having a backrest structure 1 according to the invention. The backrest structure 1 is in a lying state for supporting a child that is sleeping or resting.
The buggy 10 includes a backrest structure that is enclosed by a seat cover 2. The buggy 10 further includes a carriage frame 3 and wheels 3- 1 supporting the carriage frame 3. The backrest structure is connected to the carriage frame 3 via a flexible bearing structure 2-1 mounted to the carriage frame 3 at two opposite frame elements 3-2, 3-3, the backrest structure being located between these frame elements 3-2, 3-3. The flexible bearing structure 2-1 may selectively bear the backrest structure in a lying 5 state as shown in Fig. 1, in a sitting state as shown in Fig. 4 and in a folded state as shown in Fig. 7. By stretching or loosening the flexible bearing structure 2-1 the backrest structure can be brought from one state into another.
In the shown exemplary embodiment, the flexible bearing structure 2-1 includes a strap 2-1-1 interconnecting both frame elements 3-2, 3-3 and supportingly surrounding the backrest structure.
By tensioning the strap 2- 1-1, the backrest structure can be brought from the lying state, via the sitting state to the folded state.
Similarly, by loosening the strap 2-1-1, the seta base can be brought from the folded state, via the sitting state to the lying state.
In another embodiment, the flexible bearing structure 2-1 may include another element, as an alternative to the strap 2-1-1, for selectively bringing the backrest structure in the lying state, sitting state and folded state, e.g. using movable tube mechanism.
Figures 2 and 3 show a schematic perspective view of the backrest structure 1 according to the invention, in the lying state, from front and rear side respectively.
The backrest structure 1 includes a bottom backrest portion 1-2-1 and a top backrest portion 1-2-2. The bottom backrest portion 1-2-1 has a mainly rectangular contour formed by a bottom edge 11, a right side edge 12, a left side edge 13 and a top edge 14. Also the top backrest portion 1-2-2 has a mainly rectangular contour formed by a bottom edge 15, a right side edge 16, a left side edge 17 and a top edge 18. The bottom backrest portion 1-2-1 and the top back rest portion 1-2-2 are hingeably mounted to each via a main hinge structure 19 extending in a transverse direction, while being connected to the top edge 14 of the bottom backrest portion 1-2-1 and the bottom edge 15 of the top backrest portion 1-2-2.
The backrest structure 1 further includes a left side backrest portion 1-2-3, 1-2-4 extending along at least a substantial portion of the left side edges 13, 17 of the bottom and top backrest portions 1-2-1, 1-2-2 and being hingeably attached to the left side edges 13, 17 thereof via a left side hinge structure 1-2-6 extending in a left longitudinal direction, mainly transverse to the transverse direction. The left side backrest portion includes a bottom left side backrest portion 1-2-3 and a top left side backrest portion 1-2-4 that are mutually hingeable via a left auxiliary hinge structure 1-2-6 extending in transverse direction that is mainly aligned with the main hinge structure 1-2-5.
Similarly, the backrest structure 1 includes a right side backrest portion 1-2-3’ extending along at least a substantial portion of the right side edges 12, 16 of the bottom and top backrest portions 1-2-1, 1-2-2 and being hingeably attached to the right side edges 12, 16 thereof via a right side hinge structure 1-2-6 extending in a right longitudinal direction, mainly transverse to the transverse direction and mainly parallel to the left longitudinal direction. The right side backrest portion includes a bottom right side backrest portion 1-2-3" and a top right side backrest portion 1-2-4’ that are mutually hingeable via a right auxiliary hinge structure 1-2-6’ that 1s mainly aligned with the main hinge structure 1-2-5.
The side backrest portions 1-2-3, 1-2-3’ may be subjected to an upwardly oriented biasing force so that the side backrest portions 1-2-3, 1-2- 3’ automatically swivel upwardly when the top backrest portion 1-2-2 swivels downwardly 1.e. towards a complete open folded state wherein the bottom backrest portion 1-2-1 and the top backrest portion 1-2-2 are mainly mutually aligned. Then, the side backrest portions 1-2-3, 1-2-3’ contribute in providing an additional stiffness to the overall backrest structure 1, while also providing a side support to the child on the backrest structure 1. When a child is placed on the backrest structure 1, its weight generates a tension force on the strap 2-1-1, the strap then exerting an upwardly oriented force on the side backrest portions 1-2-3, 1-2-3" so as bring said side backrest portions 1-2-3, 1-2-3’ m a slightly upwardly oriented position.
Similarly, when the top backrest portion 1-2-2 swivels upwardly e.g. from the complete open folded state to the folded state, the side backrest portions 1-2-3, 1-2-3’ may swivel downwardly to a position wherein the side backrest portions 1-2-3, 1-2-3’ and the bottom backrest portion 1-2-1 are mainly mutually aligned so as to facilitate that the top backrest portion 1-2- 2 and the top side backrest portions 1-2-4, 1-2-4’ may swivel via the main hinge structure 1-2-5 and the auxiliary hinge structures 1-2-6, 1-2-5’, respectively, towards the bottom backrest portion 1-2-1 and the bottom side backrest portions 1-2-3, 1-2-3’, respectively.
In the shown embodiment, the main hinge structure 1-2-5 includes two folding lines 19, 20 that are mainly parallel to each other, thereby simplifying a step of swiveling the top backrest portion 1-2-2 relative to the bottom backrest portion 1-2-1, e.g. from the lying state to the sitting state, or from the sitting state to the folded state. Apparently, the main hinge structure may include further, preferably mainly parallel, folding lines so as to further facilitate a swiveling or folding movement of the top relative to the bottom back portions 1-2-2, 1-2-1. Also, in principle, the main hinge structure 1-2-5 may include a single folding line.
Also, in the shown embodiment, each of the auxiliary hinge structures 1-2-6; 1-2-6" includes two folding lines 21, 22; 21°, 22’ that adjoin a corresponding folding line 19, 20, respectively, of the main hinge structure 1-2-5 and run therefrom in a tapered manner to an exterior edge 23, 23’ of the left and right side backrest portions 1-2-3, 1-2-4; 1-2-3", 1-2-4’, respectively. By applying tapering folding lines the backrest structure 1 can be brought into the folded state, even if the side backrest portions 1-2-3, 1-2- 3, 1-2-4, 1-2-3’, 1-2-4’ are slightly folded upwardly, relative to the bottom and top backrest portions 1-2-1, 1-2-2. Preferably, when applying multiple folding lines in the main hinge structure 1-2-5, also multiple folding lines are applied in the auxiliary hinge structures 1-2-6; 1-2-6’, highly preferably such that the folding lines of the main hinge structure 1-2-5 are aligned with the folding lines of the auxiliary hinge structures 1-2-6; 1-2-6’. Further, the folding lines in the auxiliary hinge structures 1-2-6; 1-2-6’ can be mainly parallel to each other, instead of being tapered towards each other.
In the shown embodiment, the backrest structure also includes a seat base portion 1-1 that is hingeably connected to the bottom edge 11 of the bottom backrest portion 1-2-1, via a pivoting mechanism 24. Alternatively, a seat- rest unit can be provided that is separate from the set base 1.
Preferably, the backrest structure 1 includes an elastic cover layer covering an upper surface of the backrest portions i.e. the bottom backrest portion 1-2-1, the top backrest portion 1-2-2 and the side backrest portions 1-2-6; 1-2-6’, thereby rendering the backrest structure more comfortable for use, especially at the locations of the hinge structures. Further, the overall strength of the backrest structure and a robust connection between the main bottom and top backrest portions on the one hand and the side backrest portion on the other hand can be increased. However, the backrest structure 1 can also be used without an elastic cover layer, e.g. if the seat envelope cover 2 shown in Fig. 1, enclosing the backrest portions, includes user comfortable material. In yet a further embodiment, the backrest structure 1 is used without a seat envelope cover 2 shown in Fig. 1.
Generally, the backrest portions can be formed as flat or slightly curved plate-shaped elements. The backrest structure 1 or at least portions thereof, e.g. the backrest portions, can be made from a plastic material, preferably a propylene material such HDPE having the advantages of being light weight, having a uniform thickness, smooth surface, good heat resistance, high mechanical strength, excellent chemical stability, electrical insulation and non-toxicity. Further, the backrest portions can be massive or hollow.
In the lying state, as shown in Fig. 1-3, the bottom backrest portion 1-2-1, the top backrest portion 1-2-2 and the seat base portion 1-1 extend in a mainly flat plane, substantially aligned with each other.
The left and right side backrest portions 1-2-6, 1-2-6’ are slightly tilted upwardly for providing a side support to a child lying on the backrest structure 1. In the sitting state, as shown in Fig. 4-6, the bottom backrest portion 1-2-1 and the top backrest portion 1-2-2 are still extending in a mainly flat plane, substantially mutually aligned.
However, the seat base portion 1-1 now extends substantially transversely to the bottom and top backrest portions 1-2-1, 1-2-2, hinged via the pivoting mechanism 24. Again, the left and right side backrest portions 1-2-6, 1-2-6" are slightly tilted upwardly from the plane wherein the bottom and top backrest portions 1-2- 1, 1-2-2 extend, for providing the side support.
In the folded state, as shown in Fig. 7-9, the top backrest portion 1-2-2 has pivoted relative to the bottom backrest portion 1-2-1, via the main hinge structure 1-2-5 and both auxiliary hinge structures 1-2-6, 1-2-6’. The invention is not restricted to the embodiments described above.
It will be understood that many variants are possible.
It 1s noted that, in principle, the backrest structure can be implemented with a single side backrest portion as described above, at the left or the right of the bottom and top backrest portions.
Then, another side backrest portion can be provided having a top side backrest portion and a bottom side backrest portion that are separate from each other.
It is further noted that the backrest structure 1 discussed above can not only be used on a buggy but also on another movable child carrying structure such as a stroller or pushchair.
It is also noted that the main hinge structure, the auxiliary hinge structure and/or the side hinge structures can be formed from separate hinges connected to the backrest portions and/or can be integrated with a material extending across adjacent backrest portions, e.g. a material forming the elastic cover layer.
These and other embodiments will be apparent for the person skilled in the art and are considered to fall within the scope of the invention as defined in the following claims.
For the purpose of clarity and a concise description features are described herein as part of the same or separate embodiments.
However, it will be appreciated that the scope of the invention may include embodiments having combinations of all or some of the features described.
