Definitions
- the invention proposes that the wires or bars of each cross-girder be convexly bent in the longitudinal direction of said cross-girder.
- the wires or bars are loosely inserted in the associated cross-girder.
- said wires or bars of each cross-girder are rigidly joined in the cross-direction of said girder at least in one place.
- the convexly bent wires in the crossgirder may very well deflect and adapt a concave shape under a considerable load on such a cross-girder. This is particularly the case when the free bar or wire ends are not tightly connected to the longitudinal girders.
- crossgirders can easily be manufactured by means of known extrusion machines, provided that the cross-girders are made of plastics.
- the wires or bars are substantially rigidly joined in the middle by means of a substantially flat connecting member whose width substantially corresponds to the cross-girders width, and each cross-girder consists of two substantially identical parts which slide over the wires at both sides of the connecting member.
- FIG. l is a perspective view of the body supporting frame structure according to the invention
- FIG. 2 is a view of a detail of a special embodiment of a cross-girder
- a FIG. 3 is a cross-sectional view taken on the line III- III of FIG. 2.
- the framework of the two-part lying furniture frame according to FIG. I consists of longitudinal girders l and cross-girders 2.
- the lying furniture frame may also consist of more than two, say three parts, for example a foot-end rotatable about a horizontal axis, a horizontal central part and a head rotatable about a horizontal axis.
- Regularly spaced parallel cross-girders 3 are provided between the longitudinal girders I.
- Said crossgirders 3 are preferably made of plastics and at least the edges of said cross-girders are provided with a through lengthwise aperture.
- the diameter of said aperture is for example 8 to 9 mm.
- FIG. 2 clearly illustrates that the central part of each cross-girder 3 contains three through lengthwise apertures their diameters being smaller than the diameters of the apertures at the edges.
- similar cross-girders 3 can easily be manufaccontain a continous wire or bar 4..
- the wires or bars 4 are convexly bent in the longitudinal direction and give the cross-girder 3 a convex shape, thereby considerably increasing the frames resilience.
- wires 4 will preferably be spring wire, i.e., wire with favorable elastic properties, and they will preferably have a 6 to 7 mm diameter.
- the free ends 5 of the convexly bent wires 4 form a tenon for a tenon and mortise joint, for example by means of resilient supports 6, which are mounted on the longitudinal girders I.
- each cross-girder 3 In order to prevent deflexion of the convexly bent wires 4 in each cross-girder 3 under the load of the body supporting frame structure the wires 4 of each cross-girder 3 are tightly joined substantially in the middle by means of a substantially flat connecting member 7 (see FIG. 2).
- the width of the connecting member 7 equals the width of each cross-girder, and each cross-girder 3 consists of two substantially identical parts or halves which are slid over the wires 4 up to the central part 7.
- FIG. 3 clearly illustrates an embodiment of such a connecting member 7.
- This connecting member 7 contains through lengthwise apertures 8 and 9 for seizing the wires 4, for example by means of bolts and nuts which are mounted in the apertures 10.
- a body supporting furniture frame structure comprising two opposite longitudinal girders, a plurality of parallel cross-girders secured between said longitudinal girders, the longitudinal edges of each of said crossgirders being provided with a lengthwise aperture, and a wire or bar disposed through each of said lengthwise apertures, said wire or bar being convexly bent in the longitudinal direction of said cross-girders, said cross girders being constructed of flexible plastic material.
- each of said wires or bars is adapted to be loosely inserted into a lengthwise aperture of its associated cross-girder.
- a structure according to claim 1 including a plurality of connecting members each. of which is adapted to tightly connect together one of said cross-girders and its associated wires or bars in the cross direction at least in one place.
- each of said connecting members is substantially flat and has a width which is substantially equal to the width of its as sociated cross-girder.
- cross-girders are constructed of extruded plastic.
- cross-girders include at least one lengthwise aperture in addition to and intermediate the two apertures dis- UNITED STATES PATENT AND TRADEMARK OFFICE CERTIFICATE OF CORRECTION PATENT NO. 1 3,842,452
