Definitions
- the present invention generally relates to hinges and more specifically to a hinge assembly and platform suitable for use in a number of applications.
- the present invention is directed to a hinge assembly which may be incorporated into a load platform and a supporting structure.
- hinge assemblies include nondetachable members which provide articulated movement between a structure and a shelf, or load platform. However, in situations where the platform is to be easily removed from the structure, said hinge mechanisms are not appropriate.
- a further requirement for most shelves and work platforms is maintenance of a stable or rigid position of the work platform relative to the attached structure when the platform is pivoted about a hinge assembly when in a use position.
- hinge assemblies enabled the detachable yet rotatable, or pivotable, movement of a work platform with respect to a support structure
- these prior art hinges do not provide a locked position of the platform with respect to the structure to enable the platform to sustain heavy loads without other support .
- the present invention provides for an easily manufactured hinge assembly and platform which enables the detachable mounting of a platform to a structure, hinged rotation of the platform with respect to the structure, and support of the platform in an extended position, with respect to the structure, capable of bearing significant loads. Further, the present invention features a minimal number of parts, namely, two.
- the hinge assembly in accordance with the present invention generally includes a member having a lobed surface on one side thereof and a relatively flat surface on another side thereof.
- a socket provides means for receiving the member and enabling the member to turn on an axis within the socket.
- the socket generally includes means defining an opening in the socket for enabling insertion of the member into the socket at one angular relationship between the member and the socket, and preventing the separation of the member and the socket at other angular relationships therebetween.
- the socket further includes means defining opposing surfaces thereof for preventing turning of the member within the socket past a selected angle therebetween.
- an assembly When incorporated into a platform, an assembly is provided in which the platform includes an end with a lobed surface thereof and a relatively flat surface on another side thereof.
- the platform is capable of supporting a load when opposing surfaces of the socket engage opposite sides of the platform end.
- the member may include two lobed surfaces on different sides of the member, and the socket may include two cavities for receiving the two lobed surfaces.
- the two lobed surfaces are disposed on opposite sides of the member.
- Each of the cavities include spherical surfaces, and the opposing surfaces of the socket are disposed in an orientation causing the selected angle to be 90° from a one angular relationship enabling insertion of the member into the socket.
- the member may include a plurality of ears, with each ear having two lobes on different sides of each ear, and the socket includes a plurality of cavities, each sized and disposed for receiving one of the lobed surfaces.
- each of the lobed surfaces may be approximately quarterspherical and the cavities may be hemispherical .
- the present invention also encompasses a method of making the hinge assembly which includes the steps of continuously cutting lobed surfaces on one end of a first member using a cutter have a concave profile and continuously cutting sockets in another member, with a convex cutter, the sockets being sized for receiving the cut lobed surfaces.
- Figure 1 shows in perspective the hinged assembly and platform in accordance with the present invention as it may be attached to a structure, the drawing showing the platform in a folded configuration, solid lines, and in an extended, or down, position, phantom lines;
- FIG. 2 is a perspective view of a socket assembly in accordance with the present invention as it may be incorporated into the support structure;
- Figure 3 is a cross-sectional view of one of the sockets shown in Figure 2 taken along the line 3-3;
- Figure 4 is a perspective view of a platform including ears with lobed surfaces thereon, sized for insertion into the sockets shown in Figure 2;
- Figure 5 is a cross-sectional view of an ear taken along the line 5-5;
- Figure 6 is a cross-sectional view of the present invention shown in a folded configuration enabling removal of the platform from the socket;
- Figure 7 is another cross-sectional view of the present invention showing the socket with the platform in an extended position suitable for loading
- Figure 8 is a partial top view of the socket and platform taken along the line 8-8 of Figure 7;
- Figure 9 is a plan view of a member showing fabrication of a male portion of the present invention via continuous machining with a cutter;
- Figure 10 is a cross sectional view, taken along the line 10-10 of Figure 9 illustrating the fabrication of the male portion by the cutter;
- Figure 11 is a plan view of a member showing fabrication of a female portion of the present invention via continuous machining with a cutter;
- Figure 12 is a cross sectional view, taken along the line 12-12 of Figure 11 illustrating the fabrication of the female portion by the cutter.
- a hinge/platform assembly 10 generally includes a member, or platform, 12 and a socket arrangement 14 which enables pivotal coupling of the platform to a support structure 16, which may be any suitable stationary or mobile structure from which the platform, or shelf, 12 may be used in combination.
- the hinge/platform assembly 10 is removable from the support structure 16 and when extended therefrom, as hereinafter shown, can support sizeable load. Depending upon its use, this load may include that of personnel who may use the platform 12 as a step or work platform. Alternatively, the platform in the extended position may be configured by way of material construction for supporting minor loads.
- the platform 12 may be formed from any suitable material depending upon load requirements and may include ribs 20 for providing integral strength to the platform. If the hinge/platform is utilized on a portable or moveable work station, a swing-out down post 24 may be provided to prevent tipping of the work station, not shown.
- the socket assembly 14 and the platform may be constructed in any manner such as casting or machining, all of which may be suitable for specific applications.
- FIG. 2 there is shown in perspective, a socket assembly 14, in accordance with the present invention, which may be machined, as hereinabove noted, or cast from suitable plastic or metal stock which includes mounting tabs 32, 34 for securing the socket assembly 14 to the structure 16.
- a socket assembly 14 in accordance with the present invention, which may be machined, as hereinabove noted, or cast from suitable plastic or metal stock which includes mounting tabs 32, 34 for securing the socket assembly 14 to the structure 16.
- the socket assembly 14 may include a plurality of sockets 36, each having generally spherical cavities 40 for receiving opposing ends 44 of ears 46 extending from an end 50 of the platform 12 (see Figure 4) .
- the sockets 36 provide a means for receiving the end 50 of the platform 12 and enabling the platform 12 to turn about an axis within the sockets 36 (see Figure 3).
- the sockets 36 include openings 56 which enable insertion of the ears 46 thereinto, as shown in Figure 6.
- the flat surface 60 on end 50 of the platform 12 and ears 46 enable vertical insertion and removal of the panel 12 into the socket 36, as indicated by the arrow 64.
- the lobed ends 44 prevent re- separation of the platform from the socket assembly 14 and support structure 16 at any other angle other than as shown in Figure 6, in which the platform 12 and support structure 16 are generally parallel with one another.
- the socket assembly 14 further includes opposing surfaces 68, 70 which provide a means for preventing turning of the platform 12 within the socket assembly 14 past a selected angle therebetween. As shown in Figure 7, this angle may be approximately 90° from the position of the platform 12, as shown in Figure 6, i.e., the horizontal position. However, a wide range of angles can be easily accommodated.
- Opposing surfaces 68, 70 not only prevent movement of the platform past a 90° relationship with the structure 16 but also enable a significant load to be placed on the platform without additional support thereof.
- the position of the platform 12 in Figure 7 is shown in a cutaway top view in Figure 8 where it shows the ends 44 extending from ears 26 with a neck 72 interconnecting the ears 26 with the end 50 of the platform 12. As shown, a portion 76 of the ears 26 is disposed beneath the opposing surface 68 of the socket assembly 14.
- the two hinge components ie the socket assembly, or female portion, 14 and lobed ends, male portion, 44 may be economically produced by machining.
- Figures 9 and 10 illustrate fabrication of the male portion 44 in accordance with the present invention by continuous machining with a cutter 80. Cutting surfaces 82 on the cutter 80 are selected to provide the desired curvature of the male portion 44.
- the simple form cutter 80 enables the male hinge portion 44 to be generated in a single pass following the cutter path 84 as shown in Figure 9.
- An NC mill, a tracer mill, or even a hand router and template may be used.
- the socket assembly, ie female portion, 14 of the hinge is essentially the negative of the male portion 44, and is fabricated, using the same methods as hereinabove described, with a form cutter 88 as shown in Figures 11 and 12.
