Definitions

  • the table top is formed of two sections; each section has a joint flange extending perpendicularly away from the support surface of the table; a hingle interconnects the joint flanges so that the sections are foldable between an erected position in which they are in substantially the same plane and a folded position in which they are substantially parallel and form with the flanges a boxiike space; the table legs are stowable in the box-like space; a bar pivotally connected to the side of one section about two mutually perpendicular axes is swingable from a stowed position in one section over and beyond the ends of the joint flanges so that it contacts the side of the other section; and a locking device is operative to secure the free end of the bar to the side of the other section to hold the table top erected.
  • each section has a side flange which also extends perpendicularly away from the support surface of the table, and there is a gap between the ends of the joint flanges and the side flanges; the bar is then swingable into the gap from its stowed position.
  • the side flanges may be spaced slightly inwardly from the edge or" the table. Preferably however they are at the edge of the table, and so form peripheral flanges.
  • FIG. 1 is an inverted plan of a partially erected camping table according to the invention
  • FIG. 2 is a fragmentary perspective view in the direction of the arrows 2-42 in FIG. 1;
  • FIG. 3 is a fragmentary perspective view in the direction of the arrows 3-3 in FIG. 1;
  • FIG. 4 is a fragmentary perspective view of part of an erected table.
  • FIG. 5 is a fragmentary perspective View on an enlarged scale of another part of an erected table.
  • the rectangular camping table shown in FIGURE 1 has two rectangular sheet metal sections 1 and 2 respectively, whose upper sides form the support surface of the table.
  • a metal channel member 3 is fixed to the underside of and at periphery of the three outer sides I of each section, and the edge parts 4- of the three outer sides are bent over to overlie the webs 5 of the channel members.
  • the channel members thus form an L-shaped eripheral flange; one of the arms of the flange extends perpendicularly to and away from the support surface of the table, while the second arm of the flange extends inwardly and is parallel with but spaced from the table top.
  • each section is also bent over so as to form a joint flange 6, which also extends perpendicularly to and away from the table top and whose ends are spaced from the peripheral flanges by gaps 7.
  • a hinge 8 which comprises two plane metal strips s or side members pivotally connected "ice along one edge (FIG. 3), interconnects the joint flanges 6, the strips being fixed to the surfaces of the joint flanges 6.
  • the sections 1 and 2 are thus foldable between an erected position in which the sections 1 and 2 are in substantially the same plane and a folded position in which they are substantially parallel and form with the peripheral and joint flanges a box-like space.
  • each bar 10 is pivot-ally connected to a section about two mutually perpendicular axes; each pivotal connection comprises a short link 11 pivotally connected to the arms of the channel member 3 so that its axis is perpendicular to the table top, and the bar 1th is connected to the end of the link about an axis 18 parallel to the table top.
  • Each bar lit is thus swingable from the stowed position shown in FIG. 1 over and beyond the ends of the joint flanges 6 into the gap 7 between the joint flanges 6 and aligned side flanges.
  • the free end of each bar is secured to the side of the section 2 by a locking device 12, and in this way the tabie top is held erected.
  • the reference numeral 18a identifies the vertical pivot axis of link 11, at right angles to axis 18.
  • the locking device 12 is shown in more detail in FIG- URE 4. It comprises a channel member 13 slidable within the channel member 3 which constitutes the peripheral flange over the free end of the bar.
  • the channel member 13 is held within the peripheral flange by a pair of apertured lugs 14 upstanding from a plate 15, which as described later forms a mounting for a table leg.
  • the end of the channel member 13 remote from the joint flange is bent at 16 so that it is engageable with the lug 14 remote from the joint flange s to prevent its sliding clear of the lugs 14.
  • the opposite end of the channel member 13 is bent to form a handle 17, by means of which it maybe slid over and away from the free end of the bar It).
  • Each bar It is resilient, and in its unstressed condi tion is slightly curved (FIG. 1) so that it must be straightened against its resilient bias before the locking device 12 can be slid over its free end.
  • the locking device 12 is released by sliding the channel member 13 clear of the free end of the bar, the latter end springs inwardly out of the peripheral flange and clear of the device 12.
  • the table has four legs, each of which is pivotally connected to a corner of the table, so that when pivoting between the stowage position and erected position, it moves parallel to the joint flange 6.
  • each table leg in the form of a plate 15.
  • the plates 15 are each secured to an outer corner of the underside of each section, and have in addition to the lugs 14 a third apertured lug 19, which is situated nearer the other corner of the section than the lugs 14.
  • the lugs 14 and 1% are formed by bending edges of the plate into a position substantially perpendicular to the plane of the plate.
  • the apertures in the lugs 14 are aligned with each other and are perpendicular to the joint flange 6, while the plane of the lug 19 is substantially perpendicular to the flange 6 so that the axis of its aperture is parallel to the flange 6.
  • Each table leg comprises three resilient legs 21, 22, and 23 having bentover ends 24; the bent-over ends 24 of the rods 21 and 22 extend in opposite senses into and pivotally fit in the aligned apertures of the lugs 14; and the bent-over end 24 of the third rod 23 fits in the aperture of the third lug 1% so that it extends towards the other two lugs 14, the lug 19 thus in eflect constituting an abutment for the rod 23.
  • the ends of the three rods remote from the lugs are held together against the resilient bias by a common foot 25. Since the rods are stressed when the leg is erected, the resilient bias of the rods holds the bent-over ends 24 in their respective apertures in the lugs.
  • the rod 23 In order to fold a leg from the erected position of FIGURE to the stowed or folded position of FIG. 1, the rod 23 is moved against its bias so that its end 24- is moved out of the aperture in the lug 19, and is then moved towards the rods 21 and 22. The rods 21 and 22 are then pivoted about the axis of the aligned apertures in the lugs li idownwardly towards the underside of the section 1 or 2.
  • each plate 15 has an undercut part 25, in which the rod 22 of its associated table leg fits when the leg is in its stowage position. in order to fit the rod 22 in the part 26, it is forced against its bias towards the joint flange 6. Thus the undercut part 26 holds the leg in its stowage position.
  • each bar When the table is folded, each bar it) is held in its stowage position by means of a rod 21 of a table leg.
  • Each bar has a doubly bent part 27 which, in the stowed position (FIG. 1), projects towards the rods of a leg, and in which there is a notch 23.
  • the rod 21 of a table leg fits in the notch 28, and so latches the bar 19 in the stowed position.
  • One of the end peripheral flanges that is the flanges parallel to the joint flange 6is fitted with a spring clip 31 for holding the sections together in the folded position.
  • a handle 32 for carrying the table when folded is attached to a peripheral flange.
  • the joint flanges 6 need not be formed in the manner described, namely by bending over the edge part of the sections 1 and 2.
  • the metal strips 9 of the hinge 8 may have outwardly extending flanges which are secured to the underside of the sections it and 2; in this case the metal strips constitute the joint flanges.
  • the bars it) may be latched in their stowed position by means of knobs fitted to the bars instead of the notched doubly bent parts 27 of the bars.
  • a rod of a table leg fits between the knob and the bar to hold the bar in its stowed position.
  • the locking device which secures the free end of a bar to the other section may be a spring clip.
  • a rectangular foldable table comprising two sections forming a table support surface; an L-shaped peripheral flange around three of the sides of each section, one of the arms of said flange extending perpendicularly away from said support surface and the second of the arms of said flange extending inwardly and parallel with said support surface; a joint flange at the fourth edge of each of said sections extending perpendicularly away from said support surface; the ends of said joint flanges being spaced from said peripheral flanges by a gap; a hinge interconnecting said joint flanges so that said sections are foldable between an erected position in which said sections are in substantially the same plane and a folded position in which they are substantially parallel and form with said flanges a box-like space; table legs stowable in said box-like space; a short link pivotally connected to one of said sections about an axis perpendicular to said section; a bar pivotally connected to said link about an axis parallel to said one section, whereby said bar
  • a foldable table comprising (a) two equal rectangular table top forming plates, each having longitudinal and transverse edge flanges on the underside of said plates and a pair of foldable legs, adjacent longitudinal flanges being hingedly interconnected,
