Abstract: A detachable portable spring bed has a bed frame, a spring group, a cushion; the bed frame is detachable, wherein when used, the bed frame is held up, the spring is detachably assembled to the bed frame, the cushion is lay on the springs, when in packing state, the springs are detached and overlapped, the bed frame is detached to components; the spring group, the components of the bed frame, the cushion are collectively packed or independently packed. The bed frame, the spring group, the cushion are detachable.

Abstract: A spring bed with quick assembly and disassembly includes two cross bars, a plurality of vertical bars, a plurality of springs, and a plurality of fixing bases. The two cross bars and the vertical bars are parallel arranged with spacing. The two ends of the vertical bars are detachably assembled to the two cross bars. Each vertical bar is disposed with a plurality of fixing bases. The springs are detachably assembled to the fixing bases. Two ends of the vertical bar are detachably connected to the two cross bars.

Abstract: Covers for drains, manholes or similar constructions are known which comprise a first grate (10) made of sheet metal and comprising slots (11) and struts (12), said struts having top faces (13) and each strut having side faces (14, 14?) made of sheet metal bent with respect to the top face. In order to increase the rigidity it is proposed that at least a second grate (20) is provided, the struts (22) of which are inserted in the slots (11) of the first grate (10).

Abstract: A spring restraining clip mounts the axial terminus of a coil spring on the chassis via a spring seat. At least two of three spring restraining members that are circumferentially spaced on the spring restraining clip are the open type of spring restraining member so configured as to clasp and hold coil springs inserted in the axial direction, and one of the spring restraining members is a closed spring restraining member that receives the tip of a coil spring when the coil spring is rotated in the circumferential direction after having been inserted in the open type spring restraining members.

Abstract: A mattress comprising asymmetrical coil springs with nonlinear spring rates provides comfort to users with different weights. The lower portion of the spring is cylindrical and the upper portion is conical or frustoconical. This arrangement causes the spring to undergo linear compression before undergoing nonlinear compression. The result is a mattress that is sufficiently soft for lighter users and sufficiently firm for heavier users.

Abstract: A stackable wire core assembly for a bedding foundation which may be nestably stacked with numerous other such assemblies for transportation, thereby avoiding the need to compress and tie the assembly for shipping. The wire core assembly includes corrugated formed support wires having inverted U-shaped channels formed at the bottom of the corrugated formed support wires adapted to be wrapped over and secured to slats of a wooden base frame.

Abstract: A spring-support lath for supporting upholstery of furniture includes a lath body defining a longitudinal direction and having a pair of longitudinally extending U-profiles. Each U-profile is of U-shaped cross-section open in a downward direction and spaced apart in a lateral direction. The U-profiles are interconnected at their longitudinally spaced ends by end pieces and by fixed links situated intermediate the end pieces. The fixed links are spaced apart longitudinally, and at least some of the fixed links include a fastener structure such as a T-shaped member or an oblong hole for connecting to spring elements.

Abstract: Supporting spring systems for mattresses or the like usually have slats which are mounted at their opposite ends on a frame by means of elastic bearing means. It is known to individually adapt the bearing means with regard to their spring properties to the individual lying thereon. However, this alone is not adequate for sick people. The supporting spring system according to the invention is designed in such a manner that at least individual slats can be individually raised and lowered in the regions of their bearing means. This enables the supporting spring system to execute any desired movements which are transferred via the mattress to the individual lying on it. These movements of the mattress enable, in particular, prevention or treatment of bed sores. In addition, these movements are also suitable for stimulating patients with certain clinical characteristics, in particular patients whose mobility is limited and thus suffer from lack of stimulus.

Abstract: A body support apparatus, for example, a bed, includes a support surface defined by support members. Each support member is mounted for movement in a direction substantially normal to the support surface. Support members are so arranged that movement of any one of the support members in a direction substantially normal to the support surface and beyond a threshold distance relative to an adjacent support member causes movement in substantially the same direction of said adjacent support member. No movement of a support member is caused by the movement of an adjacent support member when the distance of relative movement is below the threshold distance. The support members are resiliently urged towards an unloaded position, by tension springs.

Abstract: A coupled waveband (14, 21) suspension for bed underframes, seating, upholstery, and mattresses consists of several sinusoidal wavebands (14, 21) which run parallel and/or transversely to the longitudinal axis. Support elements (12, 35) are rigidly or moveably fixed to or ride on the crests or maxima of the wavebands (14, 21). The troughs or minima are supported by slide or roll bearing elements (17) affixed to the frame. A strong interactive coupling is achieved between the support elements (12, 35) causing a positive stroke of the less pressure-loaded segments and the appropriate support elements by the simultaneous lowering of the pressure-loaded waveband segments. The wavebands (14, 21) are manufactured out of higher quality, elastically flexible sold plastic or foam material, or of spring steel band or wire, duralumin, or out of formed laminated wood.

Abstract: A bedding product comprising a conventional box spring and a pair of support members secured to the inside of the frame of the box spring. Each of the support members comprises an angle element and a pair of brackets from which supporting, adjustable feet depend. The adjustable feet are fixed in position using wing nuts. By loosening the wing nuts and rotating the adjustable feet, the height of the box spring may be adjusted.
