Abstract

A sun bed comprising a pedestal (1), a bed assembly (16) comprising a boss that engages the pedestal and is rotatable about a vertical axis relative to the pedestal, an elongate foot portion (19) fixed to the boss and having at a distal end thereof a support means for engaging the ground, and a tiltable back portion (22), said support means being shaped and arranged to support the foot portion and allow it to rotate bodily about a vertical axis on the pedestal.

Description

Sun Bed This invention relates to sun beds and in particular to sun beds that are corrosion resistant and will withstand the rigours of being left in the open and exposed to extremes of weather.

Conventional sun bed loungers are lightweight structures generally in the form of an elongate horizontal bed on fixed legs with a back portion that can be raised or lowered from the horizontal plane to provide a back support. These are generally very unstable and tip up when sat on at the foot end of the bed. They have the merit of being relatively easy to move, but require considerable space because of their "foot print".

There is a need for a reclinable sun bed that is stable and capable of supporting a wide range of weights and sizes of users and which will not tip up when sat on the foot portion. Such a sun bed predicates a heavy robust structure that is not very easily portable. There is also a need to be able to position the sun bed so that it faces the sun as the relative position of the sun moves across the sky. These two desired aims are in conflict because of the difficulty of moving the sun bed without contacting other adjacent sun beds. It will be appreciated that the expression 'sun bed' is indicative of the type of article concerned rather than being restrictive of the use to which the bed or lounger is put. A lounger having the characteristics described in the present application is considered a 'sun bed' even if it is used away from the sun, for example indoors by a swimming pool.

An object of the present invention is to provide a sun bed that is stable, and can be rotated to face the sun without having to transport the sun bed bodily to different positions.

According to the present invention there is provided a sun bed comprising a pedestal, a bed assembly comprising a boss that engages the pedestal and is rotatable about a vertical axis relative to the pedestal, an elongate foot portion fixed to the boss and having at a distal end thereof a support means for engaging the ground, and a tiltable back portion, said support means being shaped and arranged to support the foot portion and allow it to rotate bodily about a vertical axis on the pedestal.

Preferably the support means comprises a part spherical socket into which a ball fits although the support means could be one or more castor wheels. There may be two or more ball and sockets.

Preferably a bearing assembly is provided between the boss and the pedestal. In this case the pedestal has two concentric recesses in each of which is located a ball race and the boss is provided with a rim that sits on the two ball races to constitute said bearing assembly.

Preferably the bed assembly is secured to the pedestal by means that permit the bed assembly to rotate bodily about a vertical axis of the pedestal. It is preferred that the centre of gravity of the bed assembly is located at or near to a vertical axis of the pedestal.

The pedestal may be provided with a recess into which one edge of the back portion locates, said recess being shaped and positioned to permit the back portion to be tilted relative to the foot portion.

Preferably the recess is provided with notches each of which are shaped and positioned to receive and hold the edge of the back portion in a tilted position relative to the foot portion.

Ideally the recess is positioned at or near to the centre line axis of the pedestal.

The foot portion and the back portion may be provided with slits for the drainage of rainwater. The present invention will now be described by way of an example and with reference to the accompanying drawings in which:

Figure 1 is a side elevation of a sun bed lounger constructed in accordance with the present invention.

Figure 2 is a plan view of the sun bed lounger of Figure 2.

Figure 3 shows in more detail the recess in the boss of the sun bed of Figures 1 and 2 for holding the back support; and

Figure 4 shows more detail of the bearing assembly of the sun bed of Figures 1 and 2.

Referring to Figure 1 there is shown a sun bed 10 made of a plastics material such as polyurethane, ABS, rigid polystyrene or nylon. The sun bed comprises basically of a pedestal 11 which is generally cylindrical with at least three and preferably four leg portions 12. The top of the pedestal 11 has a bearing assembly 13 concentric with a vertical central axis 14 (see Figure 4).

The bearing assembly comprises a double groove 14 which has two concentric grooves 14(a), 14(b) each of a near-semi-circular cross sectional shape. Two concentric ball races 15 made of plastic balls run in the grooves 14(a), 14(b). A bed portion 16 fits on to the top of the pedestal 11. The bed portion has a cylindrical boss 17 that is dimensioned to match the size of the top of the pedestal. The boss has a rim 18 that faces the grooves 14(a), 14(b) and sits on the balls 15. The rim 18 and grooves 14(a), 14(b) together with the ball races 15 define the bearing assembly 13. The boss 17 is preferably secured to the pedestal 11 by means of a screw threaded spigot (not shown) and a nut so that the boss 17 is secured to the pedestal to keep the bearing assembly 13 together but can be rotated about a vertical axis 14.

The bed assembly 18 of the sun bed comprises a foot portion 19 which is rigidly fixed to the boss 17. The foot portion 19 has support means in the part-spherical socket 20 at its distal end into which fits a spherical ball 21 that is just clear of the ground but contacts the ground in the same plane as the base of the pedestal when the foot portion 19 is sat on. The bed 18 also includes a back support portion 22 that pivots about a pivot 23 located in the bed 18. The bed 18 is provided with a slot and recess 24 to accommodate the pivotal end of the back portion 20 as it is tilted relative to the foot portion 19 (see Figure 3).

The recess 24 has a sloping bottom edge 25 and an end face 26 against which the bottom edge 27 of the back portion 22 rests. The end face 26 has three notches 28 into which the edge 26 of the backrest 22 locates, thereby to hold the back portion 22 in one of three positions (shown in Figure 1). More than three notches 28 may be provided.

Both the foot portion 19 and the back portion 22 have slots 25 for drainage of rainwater.

The support means at the distal end of the foot portion need not be a ball 21 located in a part spherical socket 20 but it could be a castor wheel (not shown). Two or more wheels or balls could be used if desired.

The function of the support means is to prevent the foot portion 19 of the bed 18 tilting or becoming unstable when the foot portion is sat on. Preferably the foot portion 17 and the back portion 22 have a centre of gravity located at or near the vertical axis 14 about which the boss 17 rotates relative to the pedestal 11 so that the whole lounger remains balanced and stable in use, irrespective of the angle of the back portion 22 relative to the foot position 19.

The support portion 19 may be readily detachable from the pedestal and the pedestal may be designed so that, when not in use, the pedestal may be stacked on similar pedestals.
