A high density pack out gondola display rack comprises a fixed base (11), an upright (12) extending vertically from the rear of the fixed base, which upright has at least one shelf (15) supported in cantilever fashion over the fixed base. Both the base and the shelf have downwardly and forwardly sloping top surfaces (33, 24) such that product supported on the top surfaces slide forwardly against abutments (20) at the front edge of the base and shelf. A fixed display rack having multiple columns and rows of forwardly and downwardly sloping shelves (70) is mounted on the base. There are also spring-up shelves (19) adjustably supported from the upright by novel shelf supporting bracket assemblies. The shelves are preferably made from a plurality of longitudinally extending rods and a plurality of transverse rods, which rods are welded at their intersections.

A single continuous length of spring wire (10) is formed into a continuous length spiral or helix which is subsequently folded into a wave configuration for establishing in row form, a plurality of individual spring coils (12) disposed generally parallel one to another. Each coil in the row is connected at its opposite ends to adjacent coils by head or connector end sections. The head or connector end sections. The head or connector end sections (14) are then formed, preferably into a planar Z-shaped configuration such that the formed connector sections (14) at the same ends of the coils are disposed in a common plane normal to the axes of the coils which they interconnect. During forming of the end sections or heads of the coils, each connector section is deformed from a looped three-dimensional attitude into the planar Z-shaped attitude by Interengagement with novel forming pins and forming dies.

A support for tilting or synchronized chair is provided. The device (10) includes a supporting frame (12), a mobile frame (14), an elastic member (24), a stiffness adjustment mechanism coupled with the elastic member, a locking mechanism for engaging the mobile frame with the supporting frame, and an actuation device for engaging and disengaging the locking mechanism. The actuation device includes a rocker arm (36) and a return arm (40). The return arm is connected to the end of the rocker arm that the locking mechanism is attached. The rocker arm has at least two positions of stable equilibrium that are determined by the engagement or disengagement of the locking mechanism. An alternative embodiment includes an outer shell having first and second pins that are coupled with the backrest frames. The second pin may be positioned within a slot formed in the shell so that the backrest frame may move between upright and reclined positions.

The sewing machine assembly comprises a base having a work surface (11) and a sewing machine including a sewing machine drive and a stitching needle assembly (380) for sewing materials disposed on the work surface. In order to facilitate the loading and unloading of thick materials, the stitching needle assembly (380) comprises a linkage (372) coupling the sewing needle (13) to the sewing machine drive for mowing the sewing needle to provide a desired stitching pattern and means (370) unconnected to the sewing machine drive for raising and lowering the sewing needle (13) in a vertical direction with respect to the work surface independently of the sewing machine drive.
摘要:
An air bed (10) comprising an air mattress (25) having a plurality of interconnected rows and columns of air cells (35) divided into longitudinally isolated zones (41-45), and an airflow control system (15) for supplying air at differing pressures to the zones such that a person reclining atop the mattress is supported and maintained in spinal alignment at subischemic applied pressures.
摘要:
A clinical bed system (5) for monitoring and recording movements of a person while reclining or sleeping on a bed of the system. The bed includes an air mattress (25) having multiple isolated air-filled zones (41-45). Attached to each of these zones is a pressure-responsive readout device (15) which is operative to read out and record pressure changes resulting from movement of a person reclining on the air mattress.

Un logement (90) contient une pompe à air (100) et un système d'alimentation en air pressurisé d'un support du corps, tel qu'un matelas pneumatique (25). Le logement (90) contient, outre la pompe à air (100), des régulateurs de pression (R1-R4) de type à diaphragme et des soupapes d'équilibrage (CV1-CV4) de type à diaphragme, de même que des passages (180, 187, 188-191) et des chambres de compression (160, 162, 163) qui relient la pompe aux régulateurs de pression et aux soupapes d'équilibrage.
摘要:
A spring interior (21) comprising a plurality of longitudinally extending bands (22) of springs disposed side by side and connected together by helical lacing wires (23) in the top (25) and bottom faces (26) of the bands. Each band of springs comprises a single length of wire formed into a plurality of substantially vertical coil springs (31) interconnected by interconnecting segments of wire (36, 35) located alternately in the top and bottom faces of the bands. The coil springs of each row are interlaced with the adjacent coils of the same row. The spring interior is characterized by sections (20a, 20b, 20c) of differing firmness throughout the length of the spring interior. The sections (20a) of greatest firmness have such increased firmness imparted by a plurality of posture rods (62) which extend through interlaced portions of a plurality of pairs of interlaced coils of the spring interior.

A housing (90) containing an air pump (100) and an air pressure supply system for supplying air to a body support, such as an air mattress (25). The housing (90) contains, in addition to the air pump (100) diaphragm-type pressure regulators (R1-R4) and diaphragm-type surge check valves (CV1-CV4), as well as passageways (180, 187, 188-191) and pressure chambers (160, 162, 163) for interconnecting the pump to the pressure regulators and surge check valves.
摘要:
A spring interior (21) comprising a plurality of longitudinally extending bands (22) of springs disposed side by side and connected together by helical lacing wires (23) in the top (25) and bottom (26) faces of the bands. Each band of springs (22) comprises a single length of wire formed into a plurality of substantially vertical coils (31) of springs interconnected by interconnecting segments (35, 36) of wire located alternately in the top and bottom faces of the bands. Each interconnecting segment (35, 36) comprises a longitudinally extending bridging portion (37), a pair of transversely extending end portions (38), and a transversely extending support structure (40). The corners (38a, 38b) defined by the intersections between the bridging portions (37) and the end portions (38) of the interconnecting segments are radiused by radii of differing dimension so as to colinearly align the bridging portions of each band of springs. Misalignment of the bridging portions of the bands of springs had heretofore reduced the durability of the spring interior (22).
