A hinge assembly (32-36) for a frame assembly (20) of, for example, a hospital bed, has a smooth outer form which substantially conforms to the outer size of frame assembly struts to which it couples The hinge assembly (32-36) has its components located internally and provides at least one reliable electrically conductive path therethrough so as to provide an electrical connection between frame struts (24-30) coupled together by the hinge (32-36), avoiding the need for electrical wires There are provided angle markers on the hinge to indicate the degree of rotation of the hinge halves (50 52)

A hinge for bed frame assembly

Enclosure for holding an electrical device with dual access panels for safely limiting access to the device while allowing maintenance thereof. The housing defines an access opening with a limited accessing construction thereover. Interior and exterior panels are included each movable to be closed and opened. The interior panel is preferably transparent to facilitate viewing therethrough. The exterior panel is preferably metal and is hinged to the housing for movement between closed and opened positions. Individual accessing apertures can be defined in the interior and exterior panels to allow localized access by servicing personnel. Specific positioning of the access opening in the interior and/or exterior panels provides access to limited areas of the electrical device within the housing and prevents access to other areas for safety. The interior panel can have indicia imprinted thereon to facilitate servicing.

A pedal (10) is formed from a single moulding and includes first and second arms (12, 14), each provided with an over moulded marker (16, 18). The pedal (10) has two fittings (20, 22) for coupling with a brake actuator rod (24) and a coupling member (26) respectively. A castor (40) includes a wheel (42) which can rotate about a bushing (44) and a coupling shaft (46). Within the shaft (46) there is provided a brake mechanism for locking the wheel (42). A base frame (80) for a bed includes longitudinal and transverse struts (52, 54) arranged in a rectangular form, with four castors (40) and four associated pedal assemblies (10). Two actuator rods (24) are provided, one for each pair of opposing pedal assemblies (10), while two connecting elements (26) are provided, one for each pair of side-by-side pedal assemblies (10). All the pedals and thus all the brake mechanisms are coupled to one another through the two actuator rods (24) and two coupling elements (26). When one pedal (10) is actuated all the castors will either be locked or will all be released by a single operation.

A multi-layered printed circuit board (PCB) for use in items of portable electronic equipment which use a housing having a convex-concave part and/or a bent part, includes a PCB section having a uniformly thick PCB, and a resin board formed over the PCB in a part matching the internal space of the housing. By installing the multi-layered PCB having such a configuration within the housing, the internal space of the housing can be efficiently utilized.

Multi-layered printed circuit board and its manufacturing method

A housing for receiving printed circuit boards whose components form at least parts of a communication system, comprising a housing cover (3) and a connection area (11) which is accessible from the outside. A main printed circuit board (8) is arranged between the base housing part (2) and a cover part (4). Plug-in devices (23) for at least one extension printed circuit board (18) are provided in an extension area (12) of the main printed circuit board (8). A first hood (5) is provided in order to cover the extension area (12). Said hood has push- through openings (14) arranged towards the connection area (11), corresponding to plug-in devices (24) on the at least one extension printed circuit board (18) in an assembled state. The first hood (5) can engage with the cover part (4) by means of a lock connection (39) whereby said lock connection (39) can only be released using a tool.

A housing is provided with a base part to receive a plurality of equipment units, such as primed circuit boards. To facilitate access to terminal regions of the circuit boards, a two-part cover is securable to the base part, wherein a first cover part has an access opening to the terminal regions, and a ventilated second cover part covers the terminal region in a snap-fit manner. The terminal regions are thus easily accessible for measuring or testing. Preferably, the second cover part is manually releasable, without use of a tool.

A hinge which provides for a simple and fast assembly or dismantling and for an automated assembly and for use with assumed planarly fashioned hinge pin receptacles which proceed parallel to one another. A region of the hinge is fashioned as an ondular washer or Belleville spring washer in a hinge spring which is inserted between the hinge pin receptacles. The hinge spring is bent arcuately back onto itself over the edge of one of the hinge pin receptacle and is fashioned with catch elements such that these engage into an annular groove of a hinge pin introduced into the aligning bores of the hinge pin receptacles and of the ondular washer or, respectively, Belleville spring washer region.

Dieses fur eine einfache und schnelle Montage bzw. Demontage und fur eine Automatenmontage vorgesehene Scharnier setzt flachig ausgestaltete und parallel zueinander verlaufende Scharnierbolzenaufnehmer (1) voraus. This provided for a quick and easy assembly and disassembly and for automatic assembly hinge area is estimated configured and running parallel to each Scharnierbolzenaufnehmer (1). Zwischen diesen Schar nierbolzenaufnehmern (1) wird ein als Wellfeder oder Teller feder ausgebildeter Bereich (3,12) einer Scharnierfeder (4, 13) eingefugt. Nierbolzenaufnehmern between these share (1) is inserted as a wave spring or plate spring-trained field (3.12) of a hinge spring (4, 13). Diese Scharnierfeder (4, 13) ist bogenformig uber den Rand eines Scharnierbolzenaufnehmers (1) in sich zuruckgebogen und derart mit Rastelementen (7,16) ausgebil det, das diese in eine ringformige Nut (8,17) eines in die fluchtenden Bohrungen der Scharnierbolzenaufnehmer (1) und des Wellfeder- bzw. Tellerfederbereichs (3,12) eingefuhrten Scharnierbolzens (2,11) einrasten. This hinge spring (4, 13) is an arc over the edge of Scharnierbolzenaufnehmers (1) bent back and so with locking elements (7.16) ausgebil det that this in an annular groove (8.17) of the aligned holes of Scharnierbolzenaufnehmer (1) and the Wellfeder- or disc spring range (3,12) introduced the hinge pin (2.11) into place.

Hinge for fastening of pivoting electrical divices

A housing comprising a basic housing part (1) for receiving circuit boards, at least partly forming a communications system, and a housing cover which is removable to provide a fully open accessible region of the basic housing part fitted out according to requirement. Accessible connection terminals are provided on at least one side of the housing. The housing cover or closure member is made fully user-friendly by being formed of a first cover part (2) which allows full open access to the connection (terminals) area, and a second cover part (3) mechanically releasable and connected to the first part (2).
