Definitions

  • This invention relates to folding-legged furniture, and particularly, but not exclusively to items of furniture such as trestles, tables, work benches,saw horses and the like, in which the legs are foldable between an extended supporting position and a stowed position.
  • Sawhorses, trestles and the like are used by carpenters and other radesmen to support timber and other construction materials, and for supporting platforms and the like. It is conventional for sawhorses to have legs which splay out laterally, in order to provide stability; it is difficult to reconcile the requirement for the legs to splay out with the desirability for the sawhorse to be foldable so that it is easy to transport and store.
  • an item of folding-legged furniture including a top, to the underside of which a first pair of legs and a second pair of legs are each mounted on pivots in respective inverted channel-section brackets having substantially parallel opposed side walls which are inclined outwardly, the axes of the pivots being relatively inclined and movable along slots provided in said opposed side walls such that the legs may be pivotted between an extended, supporting position in which the legs are relatively laterally splayed, and a stowed position in which one leg of each pair overlies a corresponding one of the other pair.
  • the axes of the first pair of legs lie substantially in a first plane in the stowed position while the axes of the second pair of legs lie substantially in a second plane spaced from the first plane.
  • the axis of one of the first pair of legs and of the diagonally opposite leg of the second pair may lie substantially in a first plane in the stowed position, while the axis of the other of the first pair of legs and that of the remaining leg lie substantially in a second plane spaced from the first plane.
  • the axes of all the legs should be substantially parallel to one another in the stowed position, the axes being generally parallel to the long dimension of the top and to the upper surface of the top.
  • the top is typically long and narrow, such as a long and narrow rectangle.
  • the side walls of the inverted channel-section bracket are preferably inclined relative to a cross-member or web joining the side walls.
  • the brackets are generally mounted to the underside of the top in such a way that they are symmetrically disposed on the underside, relative to the longitudinal axis thereof (and preferably also relative to the transverse axis thereof).
  • the side walls are preferably such that in each bracket, opposed side walls are contiguous with the respective leg both when the legs are in the stowed position and when they are in the extended position.
  • the legs are preferably mounted in such brackets such that the pivot axis is normal to the planes of the side walls.
  • the pivot is preferably a pin extending through the respective leg, normal to the long axis thereof and through the slot provided in each side wall.
  • the top preferably includes an abutment against which each pair of legs bears when in the extended position.
  • abutments may be so located that when the legs are in the extended position they are splayed within the plane in which the legs lie, the latter plane being inclined outwardly away from the plane of the top.
  • Locking means may be provided to hold the legs against the abutments, and retained means may be provided to hold the legs in the stowed position.
  • an item of furniture in the form of a trestle has a flat elongate top 10, typically made of wood, sheet metal or plastics, to the underside of which is secured a folded sheet metal frame 11. Near each end of the top 10, two strong brackets 12 are fastened to the underside of the frame 11.
  • the brackets 12 are of inverted channel-section, having parallel side walls 13 and a connecting web 14 inclined relative to the side walls 13.
  • the top 10 and the frame 11 are supported on four identical square-section tubular metal legs 15.
  • the spacing between the side walls 13 of each bracket 12 allows one leg 15 to be received and to slide and pivot while remaining contiguous with the side walls 13 (without undue play).
  • the angle between each outwardly inclined side wall 13 and the connecting web 14 determines the angle of splay of the legs 15.
  • a pivot pin 16 fits in a transverse bore through the leg 15, near the square-cut upper end 15a thereof.
  • the pivot pin 16 also passes through parallel slots 17 in each side wall 13 of the bracket 12.
  • the slots 17 enable the leg 15 to move away from the top 10, as the leg 15 is pivotted, so that the upper end 15a of the respective leg 15 can clear the underside of the base member 14.
  • pair of legs 15 at one end are, in their supporting extended position, located by a T-shaped bar 19 against a transverse bar 18, fastened to the frame 11.
  • the centre member of the bar 19 is threaded, carries a collar 20 and extends through the bar 18.
  • the legs 15 are swung to the extended position, with the transverse member of the T-shaped bar 19 in the vertical position.
  • the bar 19 is rotated through 90° and the transverse member tightened against the back of the legs 15 by a wing nut 21 on the threaded central member of the bar 19.
  • the pivot pins 16 are transverse to the length of the frame 11, and at an acute angle to a line leading from a central line along the underside of the top 10, to the lateral edge thereof; the legs 15 can therefore be swung upwards to stowed positions which are wholly within the frame 11.
  • the axes of the legs 15 are then substantially parallel, with the legs from one end overlying the legs from the other end, as seen in Figure 6. They are located in a bracket 22, positioned centrally along the length of of the frame 11, and (in the embodiment illustrated in Figure 6) are retained by a bar 23, pulled upwards by a spring 24. The upper end of the spring 24 is received in a central member 25.
  • the legs 15 are released by pulling the bar 23 downwards and turning it clear of the legs 15 (see Figure 5).
  • the legs 15 need not be metal, but could be of wood and non-tubular and of any suitable cross-section provided the upper side faces within the bracket 12 are flat and parallel.
  • ground-engaging legs of the item of furniture according to the invention may be mitred in such a way that when the they are in the extended position, they are substantially flush with the ground.
  • the ends may have squared-off ends to which are secured ground-engaging feet which are shaped to lie substantially flush with the ground when the legs are in the extended position.
  • bracket 22 comprises a pair of channel members 26 each capable of receiving one from each end pair of legs 15, one overlying the other as shown.
  • the channel members 26 are each inclined relative to the underside 9 of the top 10 at an angle corresponding to that of the side walls 13 of bracket 12.
  • each channel member At the free end of the inner wall 27 of each channel member is an inwardly projecting lug 28; this lug has a tapered lower face 29 such that the legs 15 may be pressed past the lug, but when two legs are present in channel member 26 they are retained by the resilient action of inner wall 27 in combination with lug 28.
  • the lug further has a tapered upper face 30 such that the legs can be readily pushed past the lug and out of the channel member.
