Description

Patent description child seat

Introduction

Toddlers, ie children aged 0-3 years, need specially adapted chairs. The chair must be safe, the child must have a good sitting position and the child must come up to the right height. None of these terms are met by an ordinary dining chair for adults.

Especially in situations where the child should be seated by at a dining table, the chair should be higher than an adult chair, so that the child gets a good sitting position, with his head and arms at the right height relative to the table surface.

At home, most families with toddlers have a specially designed chair for the child. But when a family wants to sit at a table outside the home, such as visiting a restaurant, cafe or similar, a high chair is not always provided by the venue. Therefore, there is a need for a chair that is easy to bring along. This chair should be as light as possible, compact in size and it should be easy and fast to assemble.

Different types of chair adapters, that can be mounted on adult chairs, exist today. These make it possible to take advantage of the adult chair's height and stability.

One example of such a device is Chernivsky that in US3017220A describes a folding child seat that includes a frame that is placed in a car seat or on a flat surface. In this frame, a flexible seat of fabric is placed /loosely attached, wherein the child is placed.

Bluteau , Cletus and Welsh have described, in F 1191984A and US3288502A and US2854060A, respectively, foldable child seats, whose rigid foldable structure can be hung from a dining chair back when in use.

In BRMU8401900U, Pinto has described a foldable child seat, whose rigid frame is meant to be placed on the seat of an adult chair.

There also exist other solutions, but none of these accommodates all of the above wishes and needs of functionality, safety and user friendliness. Therefore, a new type of chair is presented, one that can be fastened in any dining chair, foldable, lightweight, easy and fast to mount, the child is seated at a comfortable seat at the right height and the child is seated safely.

Brief Description of the Invention

The present invention provides a cild seat which can be mounted in a standard dining chair. It includes a collapsible rigid framework and a system of straps, buckles and adjusters to keep the chair in place and mounted. A flexible seat can be hung in the rigid framework, from the system of straps, or partly in the rigid framework and partly in the straps.

The rigid structure comprises, in a preferred embodiment, of three rectangular open bails that can, by its one open side or end, be attached together rotationally around the same axis. The bails can then be turned so they are lying in the same plane and inside each other when the framework is folded. Two of the bails are configured so they are placed down in the dining chair at it's other end. The third bail can be turned in the direction of the dining chair's backrest and form a part of the child seat's backrest and sides .

The bails are arranged so that they are prevented from swinging further out from the assembled position, than to the predetermined position they should have when the chair is turned up and is in use. It will not be necessary, although it provides a more stable chair, using all of the three bails.

Any of the three bails can be removed without the chair losing its function. Therefore there are shown only two bails in other embodiments . In the other embodiments, either only one bail is configured to stand down in the seat and one to be swung up against the dining chair back, or there are two bails which stands down in the seat while the child seat back is held in place by flexible elements that are fastened in dining chair.

In yet another embodiment, one or more of the closed bails are replaced with rods that, in the same way as the bails, are mounted rotatably together by their first end and configured to stand in the seat or up against the dining chair back at their other end. These will not have a common rotation axis, but attached in pairs by each end of a rigid element that crosses the front edge of the child seat and could be folded up to this one.

The system of straps includes straps that are attached either in the rigid framework or in the flexible seat. They may also be integral or part of the flexible seat. The system includes straps that are configured to stretch the child seat against the back of the dining chair and straps that pull the child seat down into the seat of the dining chair, thus tightening the flexible seat in all directions.

The straps can run from the back of the child seat and over the back of the chair , from the back of the child seat and back further between the rear leg of the dining chair and up the back of the dining chair. In addition, the straps can run from the front leg of the highchair and fasten around the dining chair's front leg or dining chair.

Detailed description

Figure 1 gives an overview of the child seat's most important components. The child seat (1) is mounted in, and is dependent on, a adult size dining chair or similar (10). The height and structure of the adult chair is utilized. The chair (1) comprises a foldable rigid framework (2), a flexible seat (3) that can be stretched up in the rigid framework (2) and a system of straps (4) and tightening mechanisms. These three the main parts work together, so that when combined, the framework is held up, the flexible seat (3) is tightened, and the chair (1) is held firmly in the adult seat (11) without the risk of falling.

The rigid framework

In Figure 2, one can see that one embodiment of the rigid structure (2) is comprised of stiffening elements in form of three bails (5, 6, 7) that are rotatably joined together around the same axis (8). Two of the bails (5, 6) acts as a leg for the child seat (1) and stands in the adult set (11) and is tied down with straps (21, 22). The third bail, hereinafter referred to as the backbail (7), is among other things helping to stiffen up the sides and the back (9) on the child seat (1). The dimensions of the bails (5,6,7) may be such that they fit into each other and can be laid flat together when the chair is packed down. Although the shape of these bails (5, 6, 7) are rectangular and one bail (5) constitutes a full rectangle in this example, they may differ from this without losing its function.

The shape of the bails may instead of rectangles, for example, constitute three sides of a trapezoidal or they can be curved (especially for the backbail) (7)). The closed bail (5) may also be open on one side, like the others. The last side in this bail (5) can then be replaced with a rigid element (9) the other bails then are rotatably attached to, or just left as it is. As is apparent from one of the embodiments below, instead of bails, you can also employ only straight stiffening elements without any angles.

In Figure 2, one can seen that the rigid framework also employs at least one strap (25, 26) or other form of connection between the outer side of the bail (5, 6), ie the child chair's legs, and similarily between it's rear leg (6) and backrest (7). These connections mean that the three bails (5, 6, 7) will end up in the correct angle between them when rotated from each other while assembling to an unfolded chair. These connections (25, 26), as the description further shows, are also important for the framework in general.

The connections (25, 26) may also be made out of a rigid material, preferably in the form of one or more stiff and foldable rods that can be folded together when the chair is collapsed. These types of connections do not have to be attached in the outer edge of the bails, but may also be fastened to the side of the bails (5, 6, 7), be part of the flexible seat (3) or a locking device located at the rotatable attachement.

Straps

As explained above, two of the bails (5, 6) act as legs and form the bottom of the child seat (1), which is placed in the seat of the chair for adults (11). From Figures 3a and 3b, it is seen that at each of the four corners of this bottom of the structure there is attached at least one strap (21,22) which is intended to hold the chair (1) in place horizontally and downwardly (11) . These straps (21, 22) are stretched to the edge of the seat of the adult chair (11) and further either under and around the entire seat (11), around the chair back (13), or around one or several of the chairs legs (12). When the four straps (21, 22) are stretched in their respective direction, the straps (25, 26) between the outer edges of the bails (5, 6) will be held tight and will hold the bails in the correct position.

Instead of fastening the straps directly to the bottom of the bails (5, 6), they (21, 22) may be attached to the rigid structure or in the flexible seat or in other straps on the chair (1). As long as the chair is pushed down into the dining chair (11), the leg beams (5, 6) will be pressed apart and held in place by the straps (25).

At the upper edge of the bail that forms the backrest there is attached at least one strap (24) which is pulled mainly vertically and tightened over the chair back (13) on the adult chair (10). Again, the seat straps (26) are tightened to the rear of the child seat (1) while holding the backrest (7) in the correct position. Thus, when the bottom of the child seat (1) is attached to the adult chair (11) and the back (7) is tightened and fastened over the adult chair back (13), all three beams (5, 6, 7) are held in the predetermined angle relative to each other.

It is not necessary, even though it provides a more stable chair, to use all three bails. Any of the three bails can be removed without the chair losing its function. That is why in other embodiments only two bails are schematically illustrated in Figures 7a-c. In these embodiments, there is either only one bail placed in the seat and one facing the dining chair backrest, or there are two bails in the seat while the child seat back is held by flexible elements fastened in the dining chair, or there is a bail placed down in the seat and one that is swung up against the dining chair back. Common to these is that a strap (29) or the like connects the two bails thus preventing them from moving beyond the predetermined position.

Suspension of seat

In the framework (2) there is placed in a hanging position a chair (3) with a seat (30), back rest (31) and side walls (32) for the child. The chair seat (3) is of flexible material, such as textile, and it may be fastened on to the rigid framework (2) before this is folded up, as the seat will yield to the the frame (2).

The belts mentioned in this description can be replaced by anything that is suitable for keeping the parts in the correct position, such as strings, ropes, pieces of textile or rigid material without changing the function of the chair. Some of the straps and the seat itself can also be integrated parts. For example, the straps (26) from the back leg up to the back bail can be part of the backrest of the child seat (31).

When the seat is erected, the seat (3) mainly rests on the seat back (31) and the sides (32) of the backrest (7) on the structure. It may also hang completely or partially directly from the straps (23) tightened over the dining chair back (13). It is also held tightly stretched out in the following way: under the knee of the toddler seated in the chair the leg bar (6) in the front will be strached. The corners at the rear of the seat (30) can be attached directly and drawn backwards and out to the straps (26) held tight between the rear beams (5,7) or out and / or down to the rear leg (5). The back of the seat (31) will then be tensioned between the back (7) and the rear leg (5). The sides of the seat and thus the seat itself (30) are tightened in all directions; horizontally mainly between the front legs (6) and directly to the rear legs (5) and the other end of the backbone (7) or via the strap (26) at the rear edge and vertically mainly between the sides of the back bail (7) and downwards towards the front and rear legs (6, 5). This also allows the seat (30) to be stretched to all sides and kept flat.

Belts

The belts (21-29) can be configured in many different ways. In order for the child seat to be fitted in a wide range of adult chairs with different designs, they must be adaptble. Variations on chairs that should be accommodated are, for example, the height and width of the chair back, the chair seat back, how the back is attached, whether there is a gap between the back and the seat or not, the width and depth of the chair seat, the number of chair legs, where the legs are attached, etc. For example, a seat backrest that tapered against the top makes it difficult to attach anything around it, a low and a high chair back can require widely different lengths of straps to cross over them.

Figures 3-5 show different solutions. They are presented either as a whole set of straps or as elements of a layout. Several of the layouts and elements can be combined in different ways beyond what is described here, without departing from the present invention.

Preferred strap

For the vast majority of adult chairs, the following simple setup will be sufficient. As shown in Figs. 3a) and b), in this preferred embodiment, the belts (23) holding the seat backrest (7) can consist only of one or two straps (23) stretched and above the rim (15) on the back of the chair (13). These are fastened in the child seat backrest (7) or mainly in the straps (26) or in the flexible seat. Then the backrest (7) will be lifted and held in the raised position, either directly or through the attachments to the other straps or seat. These belt (s) (23) can then be stretched to the back side of the chair's back (13) and fastened in different ways depending on which other solutions are chosen for the other straps. This will be explained below in more detail. In the preferred embodiment shown in Figure 3, the straps (21) holding the rear leg (5) of the child seat (5) are stretched over the edge of the seat of the adult seat (11), further between the rear leg (12) of the adult seat and on the back of the backrest of the adult seat (13). Here they can then be attached to the straps (23) stretched from the edge of the adult chair (15) by a fastening device (43). In this way, a plurality of straps (21, 23) are tightened simultaneously, avoiding unnecessary steps during assembly.

The straps (21) attached to the back of the child seat (1) will either be attached directly to the rear leg (5) or in the flexible chair seat, with the function of tightening the chair

The solution for the straps should ensure that the child seat (1) is sufficiently pulled down, thus tight and standing down in the adult shair seat (11), and will not get pulled upwards and end up hanging from the adult backrest (13). This can be solved by configuring the fastener (43) in such a manner that the belt (23) from the backrest of the child seat (9) is threaded through a locking device (43), and then retracts upwards when tightening. In this manner, the same effect is obtained as the use of pulleys, and the force of the lower belt (21) is twice as lange as in the upper. As long as the fastening device (43) is locked Thus, the lower strap pulls more in the leg (5) than the upper strap (23) pulls in the back (7)

Straps around the back

A challenge when the child seat is placed in certain designs of adult dining chairs, is that the straps (23) that extend over the chair back can potentially slide sideways and slip over the edge (15), thus losing their function. For most chairs (10) this will not be a problem, as the framework (2) is rigid and is retained bottom. In other words, the child seat (1) can not be rolled. This allows the top of the child seat back (31) to be kept calm from sideways motion. But if the adult chair back (13) is very tall and narrow at the top, you may want to see the need to secure extra. One solution is that the straps (23) are held together by straps (27) or a whole piece of fabric, crosswise so that they can not slide apart. Also, as shown in Figures 4a and 4b, there may be added a strap (24) extending from the upper edge of the child seat and around the adult chair backing and fastened either only by itself and tightened by a fastening device (44) or attached to the other straps (23, 21) running vertically behind the adult chair back (13). Figure 4a also shows a solution to increase lateral stability. This comprises a strap fastened to the rigid structure (2) and running down to, around the side edge under and under the adult seat (11).

You can reduce the number of steps during assembly and tighten more straps at the same time as shown in Figure 5. The length of the straps (23) can be adjusted so that the straps (24) attached to the upper part of the child seat and run around the back can be pulled through slats, rings or the like (44) at the end of the backrests (23), then to move further downwards and fasten somewhere on the adult chair or, as shown in the figure, tighten against the straps (21) running from the child's legs (5, 6).

Separate fastening point

One, or more, separate fastening points (41) for the belts (23, 24) can be mounted at the upper part of the backrest of the adult chair (13). By «separately», here is meant a device that is mounted on the chair before the rest of the child seat, to establish good attachment points for this. These anchoring points (41) can be established by straps (24) which only extend around the back, or also one or more straps (28) that extend over the rim of the back and hold the strap (24). Another solution is to draw a solid hood over the backrest that tightens around this as needed. Different anchoring points can be attached to this hood. There are a variety of different strap, adjusting, locking and fastening mechanisms for straps, which are known to be known. A common locking mechanism (43) that may be used for the preferred layout of Figure 3 is, for example, a cam lock. Another illustrated in Figure 4 is pressure lock (44). In the embodiment of Figure 5, Velcro and a double D-ring (45) are used, so that straps (21, 24) can be tightened and fastened in their own right.

Alternative embodiment

Another embodiment is shown in Figure 6. Here are the bails (5, 6) that form the legs of the chair replaced by rigid rods (65, 66) and one rod (67) across the pai of legs. The backrest (7) of the above embodiments is replaced by straps (61) extending from the front of the adult chair through the rigid transverse rod (67), where it is attached, and further over the adult chair back (13) and fastened behind the back (13) in the same way as above. The child seat (3) (not shown in Figure 6) is then hung from this belt (61), similar to that of the backrest (7) in the first embodiment. This belt (61) can be combined with the straps (22) that secure the front leg of the child seat (66). This belt (61) may have a fixed length so that all lengths and dimensions of the rigid structure are predetermined, or it may include tight / regulating options to accommodate several varieties of chairs.

As in the embodiments above, there are straps (25, 26) that hold the rods (65, 66) in the correct position. In this embodiment, it is also necessary with transverse straps (67) which also hold the lower part of the rods (65, 66) in the correct position, and are tightly held by the fastening straps (21, 22). The lower ends of the rods are securely fastened in these straps (25, 26, 61)

The rods (65, 66) and (67) are held together in a fastening device (63). This can be, for example, as shown in Figure 6, rigid T-pieces or angles to which the transverse rod (67) is attached. The rods (65, 66) that act like legs are put in place from the side and held by a spring lock button (62) or other known locking mechanism so that they can loosen when the chair is packed. The lock button in the figure is attached to the rods (65, 66) and protrudes through a hole in the T-piece. The bracket (63) between the rods (65, 66) and (67) may optionally be rotatable and arranged so that the rods (65, 66) can be pivoted to the transverse rod (67), (not shown in the figures). This rotatable attachment (63) should be configured in such a way that the rods (65, 66) are stopped from rotating beyond the predetermined position they should have when the chair is mounted and ready for use. Possibly, this rotatable attachment (63) could have a locking mechanism so that the rods (65, 66) can not be reversed unintentionally. This causes the framework to be stiffened against lateral movement.

This alternative embodiment has the advantage that it can be packed into a cylindrical shape because it does not have bails which dictate the shape. When the chair is to be packed down, loosen the bars (65, 66) from the T-pieces (63) or fold in the joints.
