Abstract: A modular approach to mounting medical equipment on evacuation litters employs litter engagement members of various configuration and a plurality of rail members all having the same sectional profile. The rail members can be mounted to a variety of connectors and auxiliary pieces such that equipment supporting structures can be built on a patient bearing litter without sacrificing access to the patient.

Abstract: A portable, collapsible hammock for outdoor use has a body support surface being suspended on a position above and not touching the ground. The hammock also has a support frame comprising a pair of inclined upright arms, between which there is at least one X-scissor linkage connecting the arms. There are two connecting means disposed over the upright arms providing connections to the scissor linkage and a pair of legs. One means is a slidable connector disposed over the upright arms and the other means is fixed at the bottom end of the inclined upright arms. There is a leg/upright arm interface provides a three direction hinged joint for the connectors.

Abstract: A foldable frame assembly includes a plurality of parallel frame members, each of which has left and right columns. A plurality of coupling units are alternately disposed with the frame members, and each includes first left and right connecting rods and second left and right connecting rods. Each of the first left and right connecting rods has a first upper rod end that is pivoted to the upper column end of a respective one of the left and right columns of one of two adjacent ones of the frame members, and a first lower rod end that is opposite to the first upper rod end.

Abstract: A foldable bed frame device has a leg support frame, a flexible rectangular net disposed on the leg support frame, and a plurality of elastic fastening buttons. The flexible rectangular net has a plurality of through apertures. The leg support frame has a plurality of leg devices and a plurality of connection rods. Each connection rod is connected to two of the leg devices. Each leg device has a telescopic tube, and a connector disposed on the telescopic tube. Each connector has a round hole to match the corresponding through aperture of the flexible rectangular net. Each elastic fastening button has a click post inserted through the corresponding through aperture of the flexible rectangular net and inserted in the corresponding round hole of the connector.

Abstract: A piece of furniture includes an inflatable cushion body, a leg assembly and a coupling unit. The cushion body confines an air inflatable space therein, is provided with a valve member for inflating and deflating the cushion body, and has a bottom surface. The leg assembly is disposed below the cushion body, and has a lower portion adapted to stand on a ground surface, and an upper portion opposite to the lower portion. The coupling unit couples removably the upper portion of the leg assembly to the bottom surface of the cushion body, and includes first connecting members secured to the bottom surface of the cushion body, and second connecting members secured to the upper portion of the leg assembly to engage removably and respectively the first connecting members.

Abstract: A pantographic support control mechanism (10) for use with furniture includes one or more pantographic linkages (16). The or each linkage (16) is mounted between a forward end (104) and a rearward end (26, 106). Extension of the linkage(s) (16) causes relative movement of the forward and rearward ends (104) (26, 106) away from each other whereas contraction of the linkage(s) (16) causes relative movement of the forward and rearward ends (104) (26, 106) towards each other. One or more support means (14) are pivotally mounted with respect to and at or near respectively one or more of the pantographic linkages (16). One or more corresponding urging means (12) are arranged to act between a pantographic linkage (16) and a respective support means (14) in a manner such that extension of the or each linkage (16) causes the or each urging means (12) to respectively act on its respective support means (14) to cause it to pivot from an inoperative position to an operative position.

Abstract: An expansion bed which is easily expansible and contractible along its longitudinal direction. The bed comprises a frame having at least two support links on each side which connect front and rear upstanding frame plates. Each of the pairs of support links comprises a support leg which adjustably connects the front and rear frame plates. A plurality of arms are connected to the upper end of the support links and a plurality of mounting plates are positioned upon the support arms for receiving a mattress or other bed surface. The frame plates can be provided with rollers for facilitating movement of the bed and a stopper can be provided for preventing movement of the rollers. If desired, the mounting plates can be placed upon rather than connected to the arms and can be formed so that the widths of adjacent pairs of the plates increase in the longitudinal direction of the bed.
