Abstract

A rocking chair has a base comprising two crossed hoops (1) pivotally connected at diametrically opposite points (2). A seat structure (3) is mounted on the hoop portions above the pivot axis and has at each side a tube (5, 8) with slotted (7) studs (6, 9) which engage over the associated hoop and locate against abutments (10). The chair is held erected by a fabric seat (11) which has pockets (12) at the corners receiving the tube ends. <IMAGE>

Description

SPECIFICATION Improvements relating to chairs This invention relates to chairs. It is concerned with rocking chairs and it is intended to provide an easily assembled and dismantled chair primarily for outdoor use.

According to the present invention there is provided a rocking chair comprising two crossed hoops connected at generally diametrically opposite points to form a cradle and a seat structure supported thereby, the seat structure being rigid lateral elements spanned by a fabric szat which hangs between the ends of said elements and stays them together, and each element having slotted projections which engage over the adjacent hoop and which locate against abutments on the hoop.

Conveniently the hoops are of metal strip and the lateral elements are tubes, each element being composed of two tubes which join end to end and which are readily separated when the chair is dismantled.

For a better understanding of the invention one constructional form will now be described, by way of example, with reference to the accompanying drawings, in which: Figure 1 is a side elevation of a rocking chair, Figure 2 is a rear elevation of the chair, and Figures 3a and 3b show details of the chair.

The chair is supported on two crossed hoops 1 of metal strip. They are secured together at diametrically opposite points by bolts or rivets 2 and their upper portions form a cradle for a seat structure 3. Their lower portions provide smoothly curved rims by which the chair can rock on the ground.

The seat structure 3 is made up from steel tubes. At each side there are two tubes having a slot-together or mutually plug-in joint 4. The rear tube 5 which forms part of the back of the chair is of shallow V-form and has a stud 6 projecting laterally. This has a diametral slot 7 (Figure 3b) in its free end which engages over the associated hoop 1, the slot 7 being angled to hold the rear tube with one arm of the V inciined rearwardly about 200 from the vertical, and with the lower arm, from which the stud 6 projects, at a somewhat shallower angle. The other tube 8, which forms part of a foot support section of the chair, has a similar slotted stud 9 which engages over another part of the associated hoop. The tube 8 is of flattened Z-form.It briefly continues the lower arm of the tube 5, then turns upwardly at a shallow angle to just beyond the stud 9, and then inclines downwardly at a shallow angle. When there is downward pressure on the seat structure 3 the studs 6 and 9 tend to be forced around the hoops 1 towards the rivets or bolts 2. There is therefore provided on the inside of each hoop, just below each intended stud position, a welded-on plate 10 which provides a locking abutment.

The hoops 1 will not collapse to a much shallower X-forms (as seen in Figure 2) since the slotted studs 6 and 9 form an effective grip, and the tubes at each side are stayed together by fabric seating 11. This is a generally rectangular piece, and at each corner extending a short distance along each longer side there is a tubular portion or pocket 12, also made of fabric. These are closed at the outer ends, and open at the inner ends, and the free ends of the tubes 5 and 8 fit snugly in them. When the chair is assembled, the seating 11 hangs between the end portions which span the tubes. The seating can being single cloth, like the traditional deck chair, or be more sophisticated, for example with padded sections as shown.

It will be appreciated that this chair is readily assembled and dismantled. Generally, the hoops will be permanently connected and will only require spreading to the desired X, the bolts or rivets 2 gripping tightly enough for the hoops to maintain this set position while the seat structure is mounted. The tubes slot easily together and into the pockets 12, and the studs are readily positioned over the noops.

1. A rocking chair comprising two crossed hoops connected at generally diametrically opposite points and which can rock on the hoop portions below said points, and a seat structure mounted on the hoop portions above said points and comprising a pair of rigid lateral elements spanned by a flexible seat, each element having slotted projections which engage over the associated hoop and locate against abutments thereon.

2. A rocking chair as claimed in Claim 1, wherein the connections are pivotal with a common axis and the seat acts as a stay to hold the chair erected.

3. A rocking chair as claimed in Claim 2, wherein the lateral elements engage in pockets at the corners of said seat.

4. A rocking chair as claimed in Claim 1, 2 or 3, wherein the lateral elements are tubular.

5. A rocking chair as claimed in Claim 4, wherein each lateral element is composed of two tubes with a separable end-to-end join.

6. A rocking chair as claimed in any preceding claim, wherein the hoops are of metal strip.

7. A rocking chair substantially as hereinbefore described with reference to the accompanying drawings.
