Embodiment Construction

[0023] see figure 1 , showing a stretcher with a body support surface formed from a single sheet of flexible material divided into five sections 1a to 1e (ie, surface sections / support sections) so as to be able to be folded in a fan-fold way along fold line 2 into a compact folded state as described below. Each section 1a-1e has a rigid tube 3 of rigid material, such as a lightweight metal, usually an aluminum alloy, secured to its opposite side edges, the tube 3 on each side of the stretcher Axially aligned with the spaces 4 formed between the tubes 3 in the region of the folding lines 2 along which the sections of the stretcher are folded. In order to provide a product that is sufficiently strong and durable and at the same time as light as possible, the tubes may be made of alternative materials such as steel, titanium, carbon fibres, reinforced plastics, alloys or composite materials.

Abstract

A foldable elongate body supporting device, such as a stretcher, is described. It comprises an elongate body supporting surface 1 formed of a flexible material and a plurality of linearly aligned support sections 1a-1e. Each support section has a rigid tube 3 on each side which extends longitudinally along the device. The tubes 3 on each side of the sections are axially aligned, a space 4 being formed between each aligned tube and the aligned tube of the adjacent section. A locking member 5 is slidably located in and extending through the aligned tubes on each side of the device. The locking member 5 comprises a plurality of rigid locking tubes 6. The locking tubes 6 are movable longitudinally relative to the aligned tubes 3 between a locking position, in which the rigid tubes 6 overlap the spaces 4 between the adjacent rigid tubes to form a rigid side member on each side of the device, and a folding position in which the hinges are aligned with the spaces 4 between the aligned tubes to enable the support sections to be pivoted to a folded position.

Description

technical field [0001] The present invention relates to an elongated body support device, eg in the form of a sunbed / deck, camp bed or stretcher adapted to be folded into a compact size for easy storage and transport. Background technique [0002] Various forms of collapsible sunbeds, camp beds, chairs or stretchers are known, but none of the known devices provides a complete solution to the conflicting problem of providing a device that is both durable and strong in use and A product that is at the same time easy to fold and extend between the closed and unfolded operating positions. [0003] Known devices use a variety of hinges to allow the parts of the device to twofold relative to each other, but these hinges are very heavy and complex or relatively fragile, and are easily damaged by foreign objects, such as sand on the beach. - Damaged by intrusion. Furthermore, known products utilize clips, locks, detent pins, etc. to secure the product in the deployed operative pos...
