FIG. H

" INVENTOR SVEND ERIK BJERREGAARD SVENDSEN ATTORN EYS United States Patent 3,352,602 CONVERTIBLE CHAIR AND TABLE Svend Erik Bjerregaard Svendsen, Kastruplundgade 22, Copenhagen, Espergaerde, Denmark Filed Jan. 15, 1965, Ser. No. 479,358 12 Claims. (Cl. 297-130) The invention relates to furniture, especially a piece of child furniture, a so-called high-chair, of the type that can be used in two positions and has a frame that, in the form of a unit, is adapted to be placed in two different positions on a base, the two positions preferably being staggered 90 in relation to each other, and to support a seat at a corner of the frame in each of the two positions, and furthermore, of the type that has a table-top corresponding to one of the positions.

Furniture of the type indicated is known from the Danish patent specifications No. 30,965 and 68,901, where a table-top is provided for the first, lowest position, while in the second, highest position the high-chair is used while placed adjacent a dinner table, the child in the high-chair using the dinner table-top. This is impractical, as the child is seated uncomfortably in relation to the dinner table, and as the child easily can considerably damage the dinner table.

The object of the invention is to devise a piece of furniture of the type indicated in which the mentioned drawbacks are remedied. This is obtained according to the invention, by the fact that the piece of furniture furthermore has a table-top for the other position, both tabletops being placed substantially in a side plane of the frame with one of the edges offset in relation to the corner in question, Where the seat is placed or can be placed. This piece of furniture may be employed at meals by placing it beside a dinner table. By these means the child has its own table-top during meals, but still is in company with the adults. The table-top is placed in a manner comfortable to the child, and only the childs things are placed on the table-top, and the dinner table will not be dirtied,

According to the invention, the two table-tops may be offset in relation to one and the same corner of the frame, and a seat that in a manner per se known is adapted to be placed in two positions, may be adapted to be placed in two such positions in both of which the front edge of the seat is directed away from the corner in question. By these means a simple and practical construction is obtained. The seat plate of the seat may, according to the invention be placed pivotable around an axis at its front edge, whereas the rear edge is suspended in a back rest of pliable material, both sides of the seat plate being formed as a seating surface. Such a seat is easy and cheap to produce, and the change-over from one position to the other is easy, and the construction may easily be made in such a manner that there is no danger of an accidental opening of the fastening members of the seat as the seat may be fixedly mounted at the front edge of the seat plate and the top edge of the back rest so that it is held securely.

The back rest may, according to the invention, be placed outside the plane of the second table-top in both positions. Hereby a good back rest for the child is obtained as will be seen in the drawings.

Some embodiments of a piece of furniture according to the invention are shown in the accompanying drawings in which FIG. 1 shows a perspective view of a first embodiment of a piece of child furniture, seen obliquely from in front and with the piece of furniture in a first position,

The embodiment of the high-chair shown in FIGS. 1- 10 has a steel tube frame, two table-tops and a seat. The frame in the position shown in FIGS. 13 has two almost

vertical lengths

1 and 2, two

horizontal lengths

3 and 4, two

oblique lengths

5 and 6, and a horizontal length connecting the upper ends of the

lengths

5 and 6. To the upper ends of the

lengths

1 and 2 there are connected short oblique lengths 8 and 9, to these, two horizontal lengths 10 and 11, to these, two vertical lengths 12 and 13, and these are connected by means of a horizontal length 14. A table-top 15 is suspended from the two lengths 10 and 11 and a table-top 16 is suspended from the two lengths 12 and 13. A seat with a seat plate 17 and a back rest 18 is placed on the two

oblique lengths

5 and 6. The seat plate 17 may be substantially stiff, whereas the back rest 18 may be pliable, and the seat plate may be pivotable around an axis 19 and be swingably connected with the back rest 18 at an axis 20, and the back rest may be pivotable around an axis 21, By these means it is obtained that the seat may be turned over to the position shown in FIG. 4, the back rest being folded during this movement.

In the position shown in FIGS. 1-3 the seat plate 16 is placed relatively low, and the table-top 15 is placed at a suitable height for a child sitting on the seat. In the position shown in FIGS. 4 and 5 the seat plate is placed rather high, and the table-top 16 is preferably placed at such a height that it can project in over the table-top of an ordinary dinner table.

The table-

tops

15 and 16 arep referably detachably arranged, and when the table-tops are not in place it will be possible to pile the frames as the

lengths

1 and 2 are slightly inclined.

The seat plate 16 may be made as shown in FIG. 6. At its front edge there is placed a tube in which are placed a compression spring and two rods with outwardly projecting

ends

22 and 23 that can be pressed inwards against the spring effect and which are brought into engagement with holes in the

lengths

5 and 6. Towards the rear the seat plate has

projections

24 and 25 with bearing holes. The back rest 17 may correspondingly be made as shown in FIG. 7. It may consist of two layers of pliable material that surround filling material. At the lower edge there is placed a tube with a compression spring and two rods with outwardly projecting

ends

26 and 27 for engagement with the holes in the

projections

24 and 25. At the top edge there is also a tube with a compression spring and two rods with outwardly projecting

ends

28 and 29 for engagement with holes in the

lengths

5 and 6 just beneath the length 7. The back rest may have transverse stitchings 30 for easing the bending of the back rest during the changeover of the seat from the position shown in FIG. 2 to the position shown in FIG. 4. The

axes

19, 20 and 21 are thus formed by means of the

rod ends

22, 23, 26, 27, 28 and 29. The seat plate 16 should be made with a seating surface on both sides.

At one end the table-top has, as shown in FIG. 8,

projections

31 and 32, that form arm rests in the position shown in FIGS. 1-3. The table-top 16 has corresponding projections forming arm rests in the position shown in FIGS. 4 and 5. At its front edge the table-top 15 has

lateral fittings

33 and 34 that are made for engaging under the lengths 10 and 11 and at a small distance therefrom other

lateral fittings

35 and 36 that are adapted to engage over the lengths 10 and 11. At the rear the table-top has

lateral fittings

37 and 38 corresponding to the

fittings

35 and 36. When mounting the table-top the

fittings

33 and 34 are edged down between the lengths 10 and 11 whereafter the table-top is swung down so that it is caused to abut with the fittings 35-38 against the top side of the lengths 10 and 11. The table-top 16 may be arranged in the same manner.

The

extensions

31 and 32 and the corresponding extensions on the table-top 16 can be connected with each other by means of curved fittings 39 as shown in FIG. 10. These fittings may be fastened on one of the tabletops and may have suitable engagement members for engagement with corresponding engagement members on the other table-top so that assemblage and disassamblage is easy to carry out. The fittings may instead be fastened between the oblique lengths and 6 and the horizontal lengths and 11, so that hereby the frame is stiffened On the oblique lengths there may be placed adjustable clamping fittings40 and 41 that hold the ends of a rod 42'that can serve as a foot rest for the child in both the positions of the high-chair. Instead of a rod, a plate 43 may perhaps be used, which then should be swingable between two positions.

In FIG. 12 another embodiment of a seat is employed, namely a stiff seat construction with a seat plate 44 and a back rest 45. The seat plate and the back rest each have hooks 46 and 47 respectively with which the seat may be hooked fast on transverse rods between the

oblique lengths

5 and 6. The seat can be lifted off and be placed in the reverse position corresponidng to the other position of the high-chair as shown in FIGS. 4 and 5.

In the embodiment shown in FIG. 13 there is used a seat with a stiff seat construction consisting of a seat plate 48 and a back rest 49. The seat construction is swingably arranged on the

lengths

5 and 6 with an axis 50 so that it may be swung into the position shown with dotted lines.

In the embodiment shown in FIG. 14 a seat plate 51 is used which is swingably arranged on the

lengths

5 and 6 with an axis 52 and at the rear edge of which there are two

hinge axes

53 and 54 for two back rests 55 and 56. By these means a change-over of the seat to the two positions of the high-chair may easily be carried out.

In the embodiment shown in FIG. a seat construetion consisting of three

plates

57, 58 and 59 is employed. In the shown position 57 forms the seat plate while 58 forms the back rest. By swinging the high-chair to the other position corresponding to FIGS. 4 and 5 58 serves as seat plate while 59 serves as back rest. The steel tube frame will in this connection preferably have another shape than in the embodiment shown in FIGS. 1-5.

In the embodiment shown in FIG. 16 a seat is arranged at one end of the frame which consists of a seat plate 60 and a back rest 61. At the other end there is placed a seat plate 62 that is used when the high-chair is disposed in the position shown in FIGS. 4 and 5, a portion of the tabletop 15 serving as a back rest.

In the embodiments of FIGS. 15 and 16 no alteration of the seat or the seats is to be C d 0 i 1 .6 6 h g chair is changed over.

The shown and described embodiments are only to be considered by way of examples as diiferent variations are conceivable within the scope of the invention. The shown furniture can thus relatively easily be made in such a manthan for use by children, for example for use in classrooms or as garden furniture.

As seat for the embodiment in FIGS. 1-5 a long fiat bag may be employed which bag is foam laminated on the inside, and in the bottom half of which there is placed a stiff plate. This seat can be used instead of the one shown in FIGS. 6 and 7 and it may be suspended and employed in a similar manner. On the

oblique lengths

5 and 6 the ends of a security belt may be fastened. If the belt slides upward or downward it will only. tense more and there will therefore notbe any danger for the child to fall out.
