Abstract: A configurable foam cushioning structure for providing variable support profiles in mattress components is disclosed, and related mattress assemblies and methods. In one embodiment, a plurality of extruded support members are provided each having a top surface and a bottom surface that extend in an extrusion direction and two end surfaces that extend in a direction transverse to the extrusion direction. The extruded support members are connected to each other in a linear array defining a substantially planar lower surface, with one end surface of each of the plurality of extruded support members is substantially coplanar with the lower surface. In this manner, the structure can be easily extruded as one long, continuous piece, and reconfigured into a structure having a relatively short dimension in the extrusion direction and a relatively long dimension in the transverse direction.

Abstract: By providing a plurality of preformed components which are quickly and easily affixed in engagement with each other, a final construction is realized which peripherally surrounds any desired mattress configuration in cooperating association therewith. In this way, a new foam plastic product is achieved which is capable of being quickly and easily mounted to mattress constructions peripherally surrounding the mattress and providing an enhanced side support system. In this way, any desired mattress size or configuration is capable of being peripherally surrounded with a foam support assembly for enhancing the mattress construction and configuration. Furthermore, by employing the present invention, a rapid, convenient, and virtually labor free assembly is realized.

Abstract: The invention relates to a chuck for flexible manufacturing, said chuck comprising a chuck body, a central draw head guided axially in a central hole of the chuck body and connected to inner jaws radially guided in the chuck body through a straight-wedge mechanism, and outer jaws also radially guided in the chuck body and adapted to be equipped with chuck jaws for chucking a work-piece and to be engaged with coupling heads through rack teeth. The coupling heads are built in the inner jaws and guided axially therein, wherein said coupling heads comprise a double locking coupling device. The first locking stage of said coupling device includes wedge-shaped control members fixed to a control ring, whereas the second locking stage includes an additional locking member directly connected to the control ring. The chuck body is in the form of a one-piece unit, wherein the control ring is encased by the chuck body and the rear centering disc so that the control ring can be rotated there-between.

Abstract: The invention relates to a chuck for flexible manufacturing, said chuck comprising a chuck body (1), a central drawhead (5) guided axially in a central hole of the chuck body (1) and connected to inner jaws (4) radially guided in the chuck body (1) through a straight-wedge mechanism, and outer jaws (7) also radially guided in the chuck body (1) and adapted to be equipped with chuck jaws for chucking a work-piece and to be engaged with coupling heads (5) through rack toothings (6). The coupling heads (5) are built in the inner jaws (4) and guided axially therein, wherein said coupling heads (5) comprise a double locking coupling device. The first locking stage of said coupling device includes wedge-shaped control members (10) fixed to a control ring (9), whereas the second locking stage includes an additional locking member directly connected to the control ring (9).

Abstract: The invention relates to a chuck with chuck jaws (2) which are guided in the chuck housing (1). Inner jaws (4) which can be coupled or uncoupled are assigned directly or indirectly to said chuck jaws via rack gears (3), whereby the inner jaws (4) are connected to a central pulling head (12) via a wedging mechanism. The pulling head is connected via a rod or hollow shaft (13), said rod or hollow shaft being guided in a central bore of the main spindle (25), to the piston of a hydraulic cylinder arranged on the rear part of the main spindle (25).
