Definitions

  • the present invention relates to a bed frame assembly and in particular to a hinge structure for a configurable bed frame.
  • Configurable bed frame assemblies have been known for many years. These are provided with a bed frame formed of various portions which can be pivoted relative to one another to configure the bed from a flat configuration to different raised configurations. Typically, the portions include a back rest, a thigh rest and a leg rest. Some beds are also provided with a seat rest between the back rest and the thigh rest. The various portions can be moved or pivoted to raise a patient into a sitting position, to raise a patient's legs only to assist in vascular flow and so on. Such configurable beds have also for many years been controlled electrically, being provided with a plurality of electrically operated actuators which allow for the bed configuration to be changed by pressing one or more buttons on a key pad. Electrical systems are increasingly being incorporated into such beds to provide other functions and facilities. An example of a prior art bed assembly is the applicant's well known Contoura range of hospital beds.
  • the various portions of the bed are typically connected by hinges, either directly to one another or through connecting elements such as supports integral with a bed sub-frame.
  • the hinges are typically provided by bolts and nuts passing through two or more circular apertures in adjacent frame elements or brackets to be coupled pivotally together.
  • These hinges can cause a number of problems in maintaining the bed, particularly in a hospital or care home environment.
  • the hinges tend to form protrusions beyond the pivoted frame elements, which must be covered in order to protect patients and users and also to prevent the accumulation of dirt at the site of the hinges.
  • tarpaulins or other covers is commonplace in the industry.
  • the present invention seeks to provide an improved bed assembly and hinge structure of a bed assembly.
  • a frame assembly for a configurable bed including a plurality of movable frame portions formed from one or more frame struts and a hinge assembly including first and second hinge parts each provided with an integral connecting member, each connecting member being able to fit to respective frame struts, the hinge having an outer perimeter which presents a substantially flat surface with one or more outer surfaces of the frame struts to which it connects.
  • substantially flat surface is intended to refer to a surface which does not present a substantial protrusion from the frame struts which could trap dirt or which requires physical separation from a user such as by a cover or tarpaulin.
  • the hinge has an outer perimeter which presents a substantially flat surface with all of outer surfaces of the frame struts to which it connects.
  • the hinge connecting members are able to fit within tubular frame struts.
  • the connecting members are able to fit over an outer surface of the frame struts.

  • the hinge assembly includes an electrically conductive hinge bush provided between the first and second hinge parts.
  • the bush is preferably an interference fit with one of the hinge parts and abuts the other hinge part.
  • the bush assists in providing a reliable electrical path between the first and second hinge parts and it has been found that this is more than sufficient and permanent.
  • the hinge assembly will be provided with an electrically conductive spring element therewithin.
  • the spring element in one embodiment is a coil spring located around the bush and abutting internal walls of the first and second hinge parts. In another embodiment, the spring element is located between the bush and one of the hinge parts, for example a Belleville spring or similar.
  • first and second connecting members are provided with a fastening element, in the preferred embodiment an aperture able to receive an electrically conductive rivet or other electrically conductive fastener which would fasten together the hinge connectors to their respective frame strut, thereby providing an even more secure mechanical and electrical coupling.
  • a hinge assembly including first and second hinge parts each provided with an integral connecting member, the assembly being electrically conductive such that a conductive path is provided through the assembly from one connecting member to the other.
  • the hinge assembly includes an electrically conductive hinge bush provided between the first and second hinge parts.
  • the bush is preferably an interference fit with one of the hinge parts and abuts the other hinge part.
  • the hinge assembly is provided with an electrically conductive spring element therewithin.
  • the spring element in one embodiment is a coil spring located around the bush and abutting internal walls of the first and second hinge parts.

Coupled to the base 12 is a bed platform 20 which can be raised and lowered relative to the base 12 and tilted by means of one or more electrical actuators (not shown), also of conventional type.
  • the platform 20 is provided with a frame 22 formed, in this embodiment, of four frame sections 24, 26, 28 and 30 which are coupled to one another by means of hinged joints 32, 34 and 36.
  • Each frame section 24-30 is provided with an upper frame member having substantially vertical inner side walls 38 and a plurality of depending transverse struts 40 to form a recessed support surface for supporting a plurality of mattress support panels, described in the applicant's co-pending British patent application numbers 0514926.5 and 0523184.0.
  • the hinges 32, 34 and 36 are provided in the upper frame members 24-30 and enable the frame members to pivot relative to one another about the hinges 32-36.
  • the frame 22 is typically made of metal or a metal alloy.
  • the frame struts are, in this embodiment, tubular but could be substantially solid if preferred.
  • the frame sections 24-30 are formed from struts which are of rounded rectangular form in transverse cross-section.
  • any other cross-section could be used but it is preferred that the outer form is smooth and has rounded corners.
  • a circular outer profile is a suitable alternative.
  • the hinges 32-36 have an outer form which complements the outer form of the frame struts and present substantially flat inner and outer surfaces to the frame 20. There are no features of the hinges which protrude laterally beyond the frame sections to require special provision such as covering to protect a patient or care staff.
  • Each hinge which is made substantially entirely of metal, is formed of first and second metal or metal alloy hinge halves 50, 52 which are externally substantially identical to each other although this is not strictly necessary.
  • Each hinge half 50, 52 includes a connector element 54, 56 of a rounded rectangular outer form which is of a size to fit tightly within the inner cavity of the tubular frame struts 24-30.
  • a connector element 54, 56 of a rounded rectangular outer form which is of a size to fit tightly within the inner cavity of the tubular frame struts 24-30.
  • Each connecting element 54, 56 is also provided with a circular aperture 60 which in use receives a metal rivet 55, 57 (shown in Figure 3) or other suitable fastener which passes through a corresponding aligned hole in the associated frame strut.
  • a metal rivet 55, 57 shown in Figure 3
  • Such rivet or other fastener can fix the two elements together and guarantee a good electrical coupling, although this feature is not always necessary.
  • a rivet is preferred because of improved assembly and because it can provide a smooth rounded outer surface, which is not possible with a bolt or the like.
  • the connecting elements 54, 56 are integral with their respective hinge body members 62, 64, which members provide a shoulder 66, 68 at the junction with their respective connecting element 54, 56 of a height substantially identical to the thickness of the tubular strut such that the outer surface of the body members 62, 64 provides a substantially smooth transition from the outer surfaces of the frame struts to the outer surface of the hinge 32-36, as can be seen in Figure 3.
  • the hinge half 50 includes an inner tubular section 70 which provides a shoulder 72 which itself is at the base of a tubular recess 74.
  • the hinge half 52 includes an inner annular wall 76 circumscribing an annular boss
  • a hinge bush 86 made of metal or metal alloy in this embodiment, includes an annular base 88 and an upstanding annular wall 90 which is provided with a plurality of radially spaced longitudinally extending ribs 92.
  • the annular base 88 of the hinge bush 86 fits into the recess formed by the wall 76 and boss 78 of the hinge half 52 and when assembled touches in rotatable manner the base wall 84, as best seen in Figure 3.
  • the upstanding annular wall 90 is an interference fit into the annular wall 70 of the hinge half 50 and in practice rotates with that hinge half.
  • the assembly includes a washer 94 which, when fitted, sits on the shoulder 72 and which provides an upper stop to the position o the upstanding wall 90 of the bush 86.
  • a screw fixing in this example a button head screw 96 fits through the aperture 98 of the washer 94 and, in the preferred embodiment, engages with threads of threaded aperture 80 in the boss 78 of the hinge half 52.
  • the screw 96 has an internally threaded bore (not shown) which is then fixed to a bolt fitted into the boss 78 from the underside of the hinge half 52 when viewed in the orientation of Figure 2.
  • the washer 94 acts to urge the bush 86 against the base wall 84 of the hinge half 52, for which the upstanding wall 90 is designed to be suitably high, thereby ensuring a consistent and reliable contact and thus in practice a reliable electrical connection between the two hinge halves 50, 52.
  • all the components of the hinges 32-36 are preferably of conductive material, a plurality of conductive paths is typically present, thereby ensuring a good electrical connection during all the positions of the hinge.
  • an electrically conductive sprung element within the hinge assembly.
  • a coil spring which would fit around the upstanding wall 90 of the bushing and within the annular wall 70, of such dimensions that it is compressed against the inner surface of annular wall 76 of the hinge half 52 and against the inner surface of a similar wall (not shown) in the hinge half 50, in a manner which would be immediately apparent to a person skilled in the art.
  • a Belleville spring or washer could be placed between the base wall 84 of the hinge half 52 and the annular base 88 of the bush 86.
  • First and second cover panels 100, 102 fit over the recesses provided by the walls
  • cover panels could be of any suitable material and their coupling to the hinge body will be apparent to the skilled person, there being a variety of fixing methods known in the art.
  • FIG 4 there is shown a front view of the hinge of Figure 2 in assembled form.
  • the hinge cover 100 is provided with a plurality of angle markings 104. These note the angle between the two hinge halves 50, 52 and in practice between two frame struts coupled together by the hinge 32-36, as shown in Figure 5. Such markings are useful during the assembly of the bed frame.
  • the hinge assemblies are shown as fitting into the bed frame sections, it is envisaged that this coupling could be reversed.
  • the connecting members of the hinge halves could fit over the ends of respective frame struts, which struts could be provided with ends of reduced outer dimensions to provide shoulders similar to the shoulders 66, 68 shown in Figure 2.
  • the hinge assembly and its various components could be made of a material other than metal or metal alloy as long it can conduct electricity from one frame strut to another.
